to dawn, nor to assign the boundary where instinct assumes the
characteristics of reason. For it is no where more difficult to
discriminate between the regular operation of implanted motives, and the
result of acquired knowledge and habits, than in studying the phænomena
presented by the bee. For the present therefore I must be allowed to
regard the provinces of reason and instinct as undefinable; indeed it
seems highly probable that our limited faculties may never enable us to
acquire a knowledge of them. Still the facts which I have related, and
those which I shall proceed to detail, afford such apparently strong
evidences of a reasoning faculty, that without introducing that faculty
as their source, I shall be at a loss to explain the phænomena. +Dr.
Darwin+ in his _Zoonomia_, relates an anecdote of apparent ratiocination
in a _wasp_, which had caught a fly nearly as large as itself. Kneeling
down, the Doctor saw the wasp dissever the head and tail from the trunk
of the fly, and attempt to soar with the latter: but finding when about
two feet from the ground that the wings of the fly carried too much
sail, and caused its prize and itself to be whirled about, by a little
breeze that had arisen, it dropped upon the ground with its prey, and
deliberately sawed off with its mandibles, first one wing and then the
other: having thus removed these impediments to its progress, the wasp
flew away with its booty, and experienced no further molestation from the
wind.
Some of the proceedings of bees in glass hives cannot be referred to
their instinctive faculties,--glass being a substance which would
never be presented to them in their natural state. "Having frequently
observed," says +Dr. Evans+, "on the inside of my glass hives, prior
to the formation of cells, a number of gluey spots ranged at regular
distances, I supposed them at first to be intended as a kind of
land-marks, pointing out the divisions of the future streets, &c.
On re-examination, however, I found them evidently used as so many
footstools on the slippery glass, each bee resting on one of these with
its middle pair of legs, while the fore-claws were hooked with the hind
ones of the next above; thus forming a _living_ ladder, by which the
workers were enabled to reach the top, and pursue their favourite plan of
commencing their combs there."
A very striking illustration of the reasoning power of bees occurred
to my friend +Mr. Walond+. Inspecting his bee-boxes at the end of
October 1817, he perceived that a centre comb, burthened with honey, had
separated from its attachments, and was leaning against another comb, so
as to prevent the passage of the bees between them. This accident excited
great activity in the colony, but its nature could not be ascertained
at the time. At the end of a week, the weather being cold and the bees
clustered together, Mr. W. observed, through the window of the box, that
they had constructed two horizontal pillars betwixt the combs alluded
to, and had removed so much of the honey and wax from the top of each,
as to allow the passage of a bee: in about ten days more there was an
uninterrupted thoroughfare; the detached comb at its upper part had been
secured by a strong barrier and fastened to the window with the spare
wax. This being accomplished, the bees removed the horizontal pillars
first constructed, as being of no further use. "During this laborious
process," says Mr. W. "the glass window in the box was as warm as I had
felt it during any part of the summer, and the bees were as active within
the box."
+M. P. Huber+ of Lausanne, in his _Observations on Humble-bees_,
published in the sixth volume of the Linnæan Transactions, has given a
curious detail of some experiments in which the bees conducted themselves
somewhat similarly to those of Mr. Walond. Having inclosed twelve
humble-bees in a bell-glass, upon a table, he gave them a part of their
cones or chrysalids, containing about ten silken cocoons, and freeing
the latter as much as possible from wax, he fed the bees for some days
with pollen only. The cells containing the cones being very unequal, the
mass was so unsteady as extremely to disquiet the bees. Their affection
for their young led them to mount upon the cocoons, to impart warmth to
the inclosed larvæ: they could not do this without causing the comb to
totter or lean on one side, and having no wax for fastening the work to
the table, they had recourse to the following ingenious expedient. Two
or three bees got upon the comb, and descending to the lower edge of it,
with their heads downwards, hung from it by the hooks of their hind feet,
and clung to the table by those of the second pair, which are very long;
thus did they keep this piece of cell-work steady by their own muscular
strength. When fatigued by this constrained and irksome position, they
were relieved by their comrades; even the queen assisted. Having kept the
bees in this state till nearly the end of the third day, and shown them
to several persons, Huber introduced some honey, to enable them to form
wax: they soon constructed pillars, extending from the most projecting
parts of the cell-work to the table, and kept the cell-work in a firm
position. The wax, however, getting gradually dry, the pillars gave
way; when the poor insects adopted their former straining expedient for
steadying the comb, and continued, perseveringly, to sustain it in this
manner, till Huber took pity on them and glued the cake of comb firmly
to the table. Could the most intelligent architect have more judiciously
propped a tottering edifice, till adequate supports could be applied?
The resources of bees, when attacked by the _Sphinx Atropos_ or
_Death's-head Hawk-moth_ are much in point. In this case, according
to +Huber+, they construct small archways and various other ingenious
barricadoes, with a mixture of wax and propolis, so as just to allow the
egress and ingress of one or two workers, and effectually to exclude
their marauding enemy. The bees do not, as if guided by mere instinct,
commence their fortifications on the first attack of the Sphinx, nor
until they have been robbed of nearly their whole stock of honey. This
therefore seems to be a case in which reason is taught by experience,
and which admits in all its particulars of a direct comparison with
human reason and human contrivance. Moreover, on the cessation of
danger, and when honey-flowers were abundant, the colony prosperous
and swarms prepared to issue, these sagacious engineers demolished the
fortifications, in order to give room for the exit and entrance of the
bees. A colony that had been thus attacked in 1804, and was tardy in
its defensive preparations, having derived instruction from the past,
constructed fresh ramparts speedily, on the reappearance of the Sphinx in
1807, and thus guarded itself from impending danger.
From what has been said in page 296, it seems probable that the lives
of the working bees do not extend beyond a year, at the utmost: if
therefore my inference be legitimate, the information of the colony of
1807 must have been traditional, or else derived from a queen which had
reigned over them from 1804. On the subject of traditional information,
see Memory of Bees. It is further remarkable, as a confirmation of this
process of ratiocination and reflection, that if the apiarian apply
proper guards before the entrances to the hives, when the Sphinx makes
its appearance, the bees, finding that they are anticipated, devise no
measures of security.
I shall adduce another instance in support of my position that insects
are endowed with reason, and that they mutually communicate and receive
information. "_A German artist_ of strict veracity, states, that in his
journey through Italy, he was an eye-witness to the following occurrence.
He observed a species of _Scarabæus_ busily engaged, in making for the
reception of its egg a pellet of dung, which when finished, the insect
rolled to the summit of a hillock, and repeatedly suffered it to tumble
down the slope, apparently for the purpose of consolidating the pellet by
the adhesion of earth to it in its rotating motion. During this process,
the pellet unluckily fell into a hole, out of which the beetle was unable
to extricate it. After several ineffectual attempts, the insect went to
an adjoining heap of dung, and soon returned with three companions. All
four applied their united strength to the pellet, and at length succeeded
in pushing it out, when the three assistant beetles left the spot, and
returned to their own quarters[X]."
[Footnote X: Kirby and Spence, vol. ii. p. 522.]
+Mr. Hunter+ speaks rather sarcastically, upon the subject of reason
being one of the attributes of insects. "Reason," says he, "has been
ascribed to bees; they have been supposed to be legislators, and even
mathematicians; and though there is some show of reason for these
suppositions, there is much more of imagination." To show how far the
excursive fancy of apiarians had sometimes carried them, Mr. H. selected
a very unfortunate instance, namely, the assertion, as he calls it, that
workers' eggs may be converted into queens,--a fact which has since
been established by a series of the most satisfactory experiments. +Dr.
Virey+, in his _Nouvelle Dictionnaire d'Histoire Naturelle_, denies
that insects possess any portion of intellect, and attributes all their
operations to mere instinct, which he considers as the result of pure
mechanism, depending upon the construction of their nervous systems, in
the same manner as the tune played upon a barrel organ, is dependent on
the notes which the cylinder successively presents to its keys. +Des
Cartes+, and others before him, held a similar opinion, considering
insects as being simply susceptible of external impressions, and through
the medium of that susceptibility stimulated to act. If this doctrine be
correct, instinct is possessed alike by animals and vegetables; in short
by every thing that has life, the difference being not in quality, but in
quantity.
+Buffon+ attempted to explain the phænomena of insect life by the simple
laws of mechanism, conceding to the insects at the same time a power
of distinguishing and choosing between pleasure and pain. Some have
even ventured to assert that the invariable exactness of the cell-work
of bees is a proof of their stupidity, and "that the wonders of the
honey'd reign," no more bespeak the agency of mind or intellect, than the
configuration of salts into their respective crystals.
"Shall then proud sophists arrogant and vain.
Spurn all the wonders of the honey'd reign.
And bid alike one mindless influence own
The social bee, and crystallizing stone?
Each link they trace in animation's round,
Dashes their poison'd chalice to the ground."
+Evans.+
If this theory respecting insects were just, it should elucidate all the
phenomena which it undertakes to explain, otherwise it is injurious to
science. Examination will prove it to be a mere hypothetical opinion,
ingenious, and at first sight plausible, but completely unsatisfactory.
This theory is the natural consequence of denying to insects any portion
of intellect, and its erroneousness is shown by their capability of
instruction. Instinct itself cannot be a purely mechanical process, or it
would be incapable of modification, and would, under like circumstances,
always act in the same manner. +Sir Joseph Banks's+ _spider_ that, on
being crippled, changed from a sedentary web-weaver to a hunter, is
an instance of modified instinct[Y]. The well known fact that birds
build their nests differently, where climate and other circumstances
require a variation, is another instance. A _dog_ may be restrained from
obeying its instincts, by the intimidating recollection of a beating
which it had formerly received; a bee, if alarmed, will quit the nectary
of a flower:--here the intellect of the creatures _counteracts their
instincts_. There are other instances in which the intellect appears
to _direct the instincts_. When the bee makes excursive flights in
quest of pasture, its senses serve to guide it, and enable it, by the
aid of memory, to retrace its passage home again. At the conclusion of
its outward and homeward journeys, its instincts immediately begin to
operate; in the one case, teaching it to imbibe nectar, collect pollen,
&c.; in the other, to store and apply those materials to their respective
uses.
[Footnote Y: The account of this spider was sent to _Dr. Leach_ by _Sir
Joseph Banks_. An interesting history of it is given in the Linnæan
Transactions, vol. ii. page 393. It had lost five of its legs, which were
afterwards reproduced, but the new legs were shorter than those for which
they were substituted.]
+M. Reimar+ has denied that the lower animals possess _memory_, properly
so called; and has given it as his opinion, that they are only influenced
by past events, in consequence of having present objects before
them,--never by reflection or knowledge of the past, as being past.
But that, with them, a former impression may be renewed, without being
recollected; that it is thus rendered present to the imagination, but has
no place in the memory. For arguments and instances in support of their
being endowed with memory, see page 260. (Organs of Sensation.)
The possession of the organs of sense implies the possession of some
portion of intellect, for without intellect those organs would seem
incapable of being employed to the greatest advantage. "There is this
difference," says +Mr. Spence+, "between intellect in man, and the rest
of the animal creation. Their intellect teaches them to follow the lead
of their senses, and to make such use of the external world as their
appetites or instincts incline them to,--and _this is their wisdom:_
while the intellect of man, being associated with an immortal principle,
and connected with a world above that which his senses reveal to him,
can, by aid derived from heaven, control those senses, and render them
obedient to the governing power of his nature; and _this is his wisdom_."
A distinction has been made, and very properly, between wisdom and
knowledge. The former alone can be possessed by the lower animals, man
can possess both. The distinction between them has been very accurately
marked by +Cowper+, though in making it he has confined himself to man
only.
"Knowledge and wisdom, far from being one,
Have oft times no connection. Knowledge dwells
In heads replete with thoughts of other men,
Wisdom in minds attentive to their own."
It will, I think, be evident to my readers, from the general tenour of
this chapter, that though I make a distinction between the instinct
and the reason of bees, I do not confound their reason with the reason
of man. But to obviate all possibility of misconception, I will at once
define my meaning, when I use the terms insect reason and instinct.
By _reason_, I mean the power of making deductions from previous
experience or observation, and, thereby of adapting means to ends.
_Instinct_ I regard as a disposition and power to perform certain
actions in the same uniform manner, without reference either to
observation or experience. Those who have attended to this subject,
will be aware that _insect reason_ as above defined, is more restricted
in its functions than _the reason of man_; to which is superadded the
power of distinguishing between the true and the false, and, according
to some metaphysicians, between right and wrong. Reason, in man, has
a regular growth, and a slow progression; all the arts he practises
evince skill and dexterity, proportioned to the pains which have been
taken in acquiring them. In the lower links of creation, but little of
this gradual improvement is observable; their powers carry them almost
directly to their object. They are perfect, as +Bacon+ says, in all their
members and organs from the very beginning.
"Far different Man, to higher fates assign'd.
Unfolds with tardier step his Proteus mind,
With numerous Instincts fraught, that lose their force
Like shallow streams, divided in their course;
Long weak, and helpless, on the fostering breast,
In fond dependence leans the infant guest.
Till Reason ripens what young impulse taught.
And builds, on sense, the lofty pile of thought;
From earth, sea, air, the quick perceptions rise,
And swell the mental fabric to the skies."
+Evans.+
"Every manufacturing art," says +Dr. Reid+, "was invented by some one
man, successively improved and perfected by others; and when thus
perfected, known only by those to whom it has been taught: while in the
arts of animals no individual can claim the invention. Every animal of
the species has equal skill from the beginning, without teaching, without
experience, or habit."
"Both Instinct and Reason," says +Dr. Evans+, "appear to lose their
intensity, in proportion as their rays diverge from their proper focus;
and as they are less frequently aroused to action. A domesticated fowl
is furnished with the same apparatus as her wild sisters on the waste,
for rendering her feathers impenetrable to water: yet, living principally
under cover, she secretes much less of the oily fluid, destined for that
purpose, and makes, when accidentally wet, a most ridiculous appearance.
The force of instinctive propensities, when directed to one object, and
uninfluenced by reason, is strongly exemplified in _the idiot bee-eater
of Selborne_, mentioned by +Mr. White+, in his _History of Selborne_.
The collected powers of reason, when concentred in a single focus, is no
less finely instanced in the immortal +Newton+."
To those readers who have not seen Mr. White's account of the bee-eater,
the following abstract of it may prove acceptable.
The boy was a resident in Selborne, about the year 1750. He took great
notice of bees from his childhood, and at length used to eat them. In
summer, his few faculties were devoted to the pursuit of them, through
fields and gardens. During winter, his father's chimney corner was his
favourite haunt, where he dozed away his time, in an almost torpid state.
Practice made him so expert, that he could seize honey-bees, humble-bees
or wasps, with his naked hands, disarm them of their stings, and suck
their honey-bags, with perfect impunity. Sometimes he would store the
bees in bottles, and even in his shirt bosom. He was the terror of the
surrounding bee-keepers, whose gardens he would enter by stealth, and
rapping on the outsides of their hives, catch the bees as they came
out to see what was the matter. If in this way he could not obtain a
sufficient number to supply his wants, so passionately fond was he of
honey, that he would sometimes overturn the hives to get at it. He was
accustomed to hover about the tubs of the mead-makers, to beg a draught
of bee-wine, as he called it. As he ran about the fields he made a
humming noise with his lips, resembling that of bees. The lad was lean
in his person, and of a cadaverous unhealthy aspect: he died before he
reached the age of maturity.
CHAPTER XXXIV.
ON THE ARCHITECTURE OF BEES.
"Quel abime aux yeux du sage qu'une ruche d'abeilles? Quel sagesse
profonde se cache dans cet abime! Quel philosophe osera le
fonder!"--+Bonnet.+
The combs of a bee-hive comprise a congeries of hexagonal cells, formed
by the bees, as receptacles for honey or for embryo bees. A honey-comb is
allowed to be one of the most striking achievements of insect industry,
and an admirable specimen of insect architecture. It has attracted the
admiration of the contemplative philosopher in all ages, and awakened
speculation not only in the naturalist, but also in the mathematician:
so regular, so perfect, is the structure of the cells, that it satisfies
every condition of a refined problem in geometry. Still a review of their
proceedings will lead to the conclusion, as +Huber+ has observed, that
"the geometrical relations, which apparently embellish the productions
of bees, are rather the necessary result of their mode of proceeding,
than the principle by which their labour is guided." "We must therefore
conclude, that the bees, although they act geometrically, understand
neither the rules nor the principles of the arts which they practise so
skilfully, and that the geometry is not in the bee, but in the great
Geometrician who made the bee, and made all things in number, weight and
measure[Z]."
[Footnote Z: Reid.]
Before the time of +Huber+, no naturalist had seen the commencement
of the comb, nor traced the several steps of its progress. After many
attempts, he at length succeeded in attaining the desired object, by
preventing the bees from forming their usual impenetrable curtain, by
suspending themselves from the top of the hive; in short, he obliged them
to build upwards, and was thereby enabled, by means of a glass window, to
watch every variation and progressive step in the construction of comb.
_Each comb in a hive is composed of two ranges of cells backed against
each other: these cells_, looking at them as a whole, may be said to
_have one common base_, though no one cell is opposed directly to
another. This base or partition between the double row of cells is
so disposed as to form a pyramidal cavity at the bottom of each, as
will be explained presently. _The mouths of the cells_, thus ranged on
each side of a comb, _open into two parallel streets_ (there being a
continued series of combs in every well filled hive). These streets are
sufficiently contracted to avoid waste of room and to preserve a proper
warmth, yet _wide enough to allow the passage of two bees abreast_.
Apertures through different parts of the combs are reserved to form near
roads, for crossing from street to street, whereby much time is saved to
the bees.
"These in firm phalanx ply their twinkling feet,
Stretch out the ductile mass, and form the street,
with many a cross-way path and postern gate.
That shorten to their range the spreading state."
+Evans.+
_The bees_, as has been already observed, _build their cells of an
hexangular form, having six equal sides_, with the exception of the first
or uppermost row, the shape of which is an irregular pentagon, the roof
of the hive forming one of the members of the pentagon, thus:
[Illustration]
"There are only three possible figures of the cells," says +Dr. Reid+,
"which can make them all equal and similar, without any useless
interstices. These are the equilateral triangle, the square and the
regular hexagon. It is well known to mathematicians that there is not a
fourth way possible, in which a plane maybe cut into little spaces that
shall be equal, similar, and regular, without leaving any interstices."
Of these three geometrical figures, the hexagon most completely unites
the prime requisites for insect architecture. The truth of this
proposition was perceived by +Pappus+, an eminent Greek philosopher and
mathematician, who lived at Alexandria in the reign of Theodosius the
Great, and its adoption by bees in the construction of honey-comb was
noticed by that ancient geometrician. These requisites are;
First, Œconomy of materials. There are no useless partitions in a
honey-comb, each of the six lateral pannels of one cell forms also one
of the pannels of an adjoining cell; and of the three rhombs which form
the pyramidal base of a cell, each contributes one-third towards the
formation of the bases of three opposing cells, the bottom or centre of
every cell resting against the point of union of three pannels that are
at the back of it.
Secondly, Œconomy of room; no interstices being left between adjoining
cells.
Thirdly, The greatest possible capacity or internal space, consistent
with the two former desiderata.
Fourthly, Œconomy of materials and œconomy of room produce œconomy of
labour. And in addition to these advantages, the cells are constructed
in the strongest manner possible, considering the quantity of materials
employed. Both the sides and bases are so exquisitely thin, that three
or four placed on each other are not thicker than a leaf of common
writing-paper; each cell, separately weak, is strengthened by its
coincidence with other cells, and _the entrance is fortified with an
additional ledge or border of wax_, to prevent its bursting from the
struggles of the bee-nymph, or from the ingress and egress of the
labourers. This entrance border is _at least three times as thick as
the sides of the cell_, and thicker at the angles than elsewhere, which
prevents the mouth of the cell from being regularly hexagonal, though the
interior is perfectly so.
"On books deep poring, ye pale sons of toil.
Who waste in studious trance the midnight oil,
Say, can ye emulate with all your rules.
Drawn or from Grecian or from Gothic schools.
This artless frame? Instinct her simple guide,
A heaven-taught Insect baffles all your pride.
Not all yon marshal'd orbs, that ride so high.
Proclaim more loud a present Deity,
Than the nice symmetry of these small cells,
Where on each angle genuine science dwells.
And joys to mark, through wide creation's reign,
How close the lessening links of her continued chain."
+Evans.+
I have just adverted to the ingenuity of the bees in thickening, and
thereby strengthening the mouths of the cells. _Additional strength is
also derived from the bees covering the whole surface of the combs,
but more particularly the edges of the cells, with a peculiar kind of
varnish_, which they collect for the purpose. At first the combs are
delicately white, semitransparent, and exceedingly fragile, smooth but
unpolished: in a short time their surfaces become stronger, and assume
more or less of a yellow tint. The deepening of the colour of honey-combs
has been supposed, by some, to be the effect of age; and in part it may
be: but it is principally owing to the coat of varnish with which the
bees cover them. This varnish strongly resembles propolis, appearing to
differ from it only in containing the colouring material which imparts
to wax its yellow hue. The source of this colouring matter has not
been discovered: it is insoluble in alcohol; but the manufacture of
white wax shows that it is destructible by light.--But to return to the
construction of the cell-work.
_The pyramidal basis of a cell is formed by the junction of three
rhomboidal or lozenge-shaped portions of wax;_ thus,
[Illustration]
the apex of the pyramid being situated where the three obtuse angles of
the lozenges meet. To the exterior edges and angles are attached the
six pannels or sides of each cell. The apex of each pyramidal bottom,
on one side of a comb, forms the angles of the bases of three cells on
the opposite side, the three lozenges respectively concurring in the
formation of the bases of the same cells. This will I hope explain what
is meant by "each cell separately weak, being strengthened by coincidence
with others." The bottom of each cell rests upon three partitions of
opposite cells, from which it receives a great accession of strength.
As it is desirable that the reader should thoroughly comprehend this
subject, I will restate it in other words.--The partition which separates
the two opposing rows of cells, and which occupies, of course, the middle
distance between their two surfaces, is not a plane but a collection of
rhombs, there being three at the bottom of each cell: the three together
form in shape a flattened pyramid, the basis of which is turned towards
the mouth of the cell; each cell is in form therefore an hexagonal prism,
terminated by a flattened trihedral pyramid, the three sides of which
pyramid are rhombs, that meet at the apex by their obtuse angles. The
plates underneath, represent the opposite surfaces of the pyramidal bases
of adjoining cells, and will, I trust, enable the reader to understand
the foregoing description.
[Illustration]
The union of the lozenges in one point, in addition to the support which
it is the means of affording to the three partitions between opposing
cells, is also admirably adapted to receive the little egg and to
concentrate the heat necessary for its incubation.
Each obtuse angle of the lozenges or rhombs forms an angle of about
110°, and each acute one, an angle of about 70°. +M. Maraldi+ found by
mensuration that the angles of these rhombs which compose the base of
a cell, amounted to 109° 28′ and 70° 32′; and the famous mathematician
+Kœnig+, pupil of the celebrated Bernouilli, having been employed for
that purpose by +M. Reaumur+, has clearly shown, by the method of
infinitesimals, that the quantity of these angles, using the least
possible wax, in a cell of the same capacity, should contain 109° 26′
and 70° 34′. This was confirmed by the celebrated +Mr. McLaurin+, who
very justly observes, that the bees do truly construct their cells of the
best figure, and with the utmost mathematical exactness.
The construction of several combs is generally going on at the same
time. No sooner is the foundation of one laid, with a few rows of cells
attached to it, than a second and a third are founded on each side,
parallel to the first, and so on, (if the season give encouragement to
the operations of the bees,) till the hive is filled with their works;
the first constructed comb or combs being always in the most advanced
state, and therefore the first to be completed.
_The design of every comb is sketched out, and the first rudiments are
laid, by one single bee._ This founder-bee forms a block, out of a rough
mass of wax, drawn partly from its own resources, but principally from
those of other bees, which furnish materials, in quick succession, from
the receptacles under their bellies, taking out the plates of wax with
their hind feet, and carrying them to their mouths with their fore-feet,
where the wax is moistened and masticated, till it becomes soft and
ductile.
Thus, "filter'd through yon flutterer's folded mail,
Clings the cool'd wax, and hardens to a scale.
Swift, at the well-known call, the ready train
(For not a buz boon Nature breathes in vain,)
Spring to each falling flake, and bear along
Their glossy burdens to the builder throng."
+Evans.+
The architect-in-chief, who lays, as it were, the first stone of this and
each successive edifice, determines the relative position of the combs,
and their distances from each other: these foundations serve as guides
for the ulterior labours of the wax-working bees, and of those which
sculpture the cells, giving them the advantage of the margin and angles
already formed.
The expedients resorted to by that ingenious naturalist, +Huber+,
unfolded the whole process. He saw each bee extract with its hind feet
one of the plates of wax from under the scales where they were lodged,
and carrying it to the mouth, in a vertical position, turn it round; so
that every part of its border was made to pass, in succession, under
the cutting edge of the jaws: it was thus soon divided into very small
fragments; and a frothy liquor was poured upon it from the tongue, so as
to form a perfectly plastic mass. This liquor gave the wax a whiteness
and opacity which it did not possess originally, and at the same time
rendered it tenacious and ductile. The issuing of this masticated mass
from the mouth was, no doubt, what misled Reaumur, and caused him to
regard wax as nothing more than digested pollen.
The mass of wax, prepared by the assistants, is applied by the
architect-bee to the roof or bottom of the hive, as the case may be;
and thus a block is raised of a semi-lenticular shape, thick at top
and tapering towards the edges. When of sufficient size, a cell is
sculptured on one side of it, by the wax-working bees, who relieve one
another in succession, sometimes to the number of twenty, before the
cell is completely fashioned. At the back and on each side of this first
cell, two others are sketched out and excavated. By this proceeding the
foundations of two cells are laid, the line betwixt them corresponding
with the centre of the opposite cell. As the comb extends, the first
excavations are rendered deeper and broader; and when a pyramidal base
is finished, the bees build up walls from its edges, so as to complete,
what may be called, the prismatic part of the cell. Every succeeding row
of cells is formed by precisely similar steps, until there is sufficient
scope for the simultaneous employment of many workers.
"These, with sharp sickle, or with sharper tooth,
Pare each excrescence, and each angle smooth,
Till now, in finish'd pride, two radiant rows,
Of snow-white cells, one mutual base disclose.
Six shining pannels gird each polish'd round.
The door's fine rim, with waxen fillet bound,
While walls so thin, with sister walls combin'd.
Weak in themselves, a sure dependence find."
+Evans.+
The pyramidal bases and lateral plates are successively formed, with
surprising rapidity: the latter are lengthened as the comb proceeds, for
the original semi-lenticular form is preserved till towards the last,
when if the hive or box be filled, the sides of all the cells receive
such additions as give them equal depth.
_The cells intended for the drones_ are considerably larger, and more
substantial, than those for the working bees, and, being later formed,
usually appear near the bottom of the combs. Last of all are built the
_royal cells_, the cradles of the infant queens: of these there are
usually three or four, and sometimes ten or twelve, in a hive, attached
commonly to the central part, but not unfrequently to the edge or side of
the comb. +Mr. Hunter+ says that he has seen as many as thirteen royal
cells in a hive, and that they have very little wax in their composition,
not one-third, the rest he conceives to be farina. Such is the genuine
loyalty of bees, that the wax which they employ with so much geometric
œconomy, in the construction of hexagonal cells, is profusely expended on
the mansions of the royal bee-nymph, one of these exceeding in weight a
hundred of the former. They are not interwoven with them, but suspended
perpendicularly, their sides being nearly parallel to the mouths of the
common cells, several of which are sacrificed to support them.
"No more with wary thriftiness imprest,
They grace with lavish pomp their royal guest,
Nor heed the wasted wax, nor rifted cell.
To bid, with fretted round, th' imperial palace swell."
+Evans.+
The form of these royal cells is an oblong spheroid, tapering gradually
downwards, and having the exterior full of holes, somewhat resembling the
_rustic_ work of stone buildings. The mouth of the cell, which is always
at its bottom, remains open till the maggot is ready for transformation,
and is then closed as the others are.
Immediately on the emergence of a ripened queen, the lodge which she
inhabited is destroyed, and its place is supplied by a range of common
cells. The site of this range may always be traced, by that part of the
comb being thicker than the rest, and forming a kind of knot; sometimes
the upper portion of the cell itself remains, like an inverted acorn-cup,
suspended by its short peduncle.
"Yet no fond dupes to slavish zeal resign'd,
They link with industry the loyal mind.
Flown is each vagrant chief? They raze the dome,
That bent oppressive o'er the fetter'd comb,
And on its knotted base fresh gamers raise.
Where toil secure her well-earn'd treasure lays."
+Evans.+
In this mutilated state only, and not in the breeding season, could Mr.
Hunter have seen this cradle of royalty; for he describes it as the half
of an oval, too wide and shallow to receive its supposed tenant. The
following sketch affords; a representation of the hexagonal cells of a
comb, and also the attachment of the royal cradles.
[Illustration]
I have spoken of the perfect regularity in the cell-work of a
honey-comb;--particular circumstances, however, induce a departure from
this exactness: for instance, where bees have commenced a comb with
small cell-work, and afterwards wish to attach to it a set of large
cells, as in the case of drone-cells being required to be appended to
workers-cells. These deviations from the usual regularity renew our
admiration of bee-ingenuity, though Reaumur and Bonnet have regarded them
as examples of imperfection. They effect their object by interposing
three or four series of, what may be called, _cells of transition_, the
bottoms or bases of which are composed of two rhombs and two hexagons,
instead of three rhombs; the rhombs and hexagons gradually varying in
form and relative proportion, till the requisite size, namely that of
the cells which they are approaching, has been attained. The following
outlines will serve to convey to the reader the regular steps in this
progressive increase.
[Illustration]
The same gradation is observed when returning to smaller cells. Every
apparent irregularity is therefore determined by a sufficient motive, and
forms no impeachment of the sagacity of the bee.
The common breeding-cells of drones or workers are, occasionally, (after
being cleaned,) made the depositories of honey; but the cells are never
made so clean, as to preserve the honey undeteriorated. The finest honey
is stored in new cells, constructed for the purpose of receiving it,
their configuration resembling precisely the common breeding-cells: these
_honey-cells vary in size_, being made more or less capacious, _according
to the productiveness of the sources from which the bees are collecting_,
and _according to the season of the year_: the cells formed in July and
August vary in their dimensions from those that are formed earlier; being
intended for honey only, they are larger and deeper, the texture of
their walls is thinner, and they have more dip or inclination: this dip
diminishes the risk of the honey's running out, which from the heat of
the weather, and the consequent thinness of the honey, at this season of
the year, it might otherwise be liable to do. _When the cells_, intended
for holding the winter's provision, are filled, _they are always closed
with waxen lids_, and never re-opened till the whole of the honey in the
unfilled cells has been expended. The waxen lids are thus formed;--The
bees first construct a ring of wax within the verge of the cell, to which
other rings are successively added, till the aperture of the cell is
finally closed with a lid composed of concentric circles.
The brood-cells, when their tenants have attained a certain age, are also
covered with waxen lids, like the honey-cells; the lids differ a little,
the latter being somewhat concave, the former convex. _The depth of the
brood-cells_ of drones and working bees is about half an inch; _their
diameter_ is more exact, that of the drone-cells being 3⅓ lines[AA],
that of the workers 2⅗ lines. These, says Reaumur, are the invariable
dimensions of all the cells, that ever were, or ever will be made.
[Footnote AA: A line is the twelfth part of an inch.]
From this uniform, unvarying diameter of the brood-cells, when completed,
their use has been suggested, as an universal standard of measure, which
would be understood, in all countries, to the end of time.
"While heav'n-born Instinct bounds their measur'd view,
From age to age, from Zembla to Peru,
Their snow-white cells, the order'd artists frame,
In size, in form, in symmetry the same."
+Evans.+
CHAPTER XXXV.
AN INQUIRY INTO THE SOURCE AND NATURE OF BEES-WAX.
It has long been very generally and implicitly believed, that the yellow
matter (in other words, the pollen or farina of flowers,) which bees
visibly collect upon their thighs, is the prime constituent of wax, the
material of the honey-comb. Even +Bonnet+ and +Reaumur+ were of this
opinion. +Burler+, +Purchas+, +Rusden+ and +Thorley+ have argued against
its identity with wax; and I trust that the observations and experiments
which I am about to detail, will convince the dispassionate inquirer of
the fallacy of this old opinion.
In the first place, It is to be observed, that where no more comb can be
built, as in old hives, the bees carry in the greatest quantity of this
yellow matter.
Secondly, That it differs materially from wax, the latter when examined
between the fingers being adhesive, the former crumbly; the latter also
liquefying on the application of heat, whilst the former burns to ashes.
Thirdly, That the wax of new combs, from whatever source collected,
is uniformly white; whereas the farina, as gathered by the bees, is
always black, yellow, or red, agreeing in colour with the anther-dust
of the flowers in blossom at the time of its collection. Moreover, the
farina, after it has been stored in the cells, retains its original
colour, whilst wax invariably changes, first to a yellow, and lastly to
a blackish tint. Layers of different-coloured farina are generally found
in the cells, if slit down; and every hive, at the season of deprivation,
possesses a store of it.
Fourthly, That fresh colonies carry in very little, if any, of this
matter, for some days after swarming, though combs are formed within that
period. I noticed this fact in my first colony: the swarm issued from the
parent hive on the 18th of May;--five days of rainy weather succeeded:
during this period the bees were prevented from flying abroad; I fed
them nightly with sugared ale, and before the return of fine weather a
considerable quantity of comb was formed. Now excepting such materials
as the bees might have brought with them from the parent hive, in this
case, the sugared ale alone must have been the source of the wax. +Huish+
has remarked that unless bees have access to water, and also to sugar
or honey, no comb can be formed. Again, it may be observed, that upon
the storifying plan, when fresh works are commenced in the duplets or
triplets, if the farina were the basis of the combs, an increased
quantity should be carried in. On the contrary, though I have watched
the bees very minutely on these occasions, I scarcely ever witnessed
the introduction of farina; and in such rare instances as I did observe
it, it might fairly be regarded as food for the young larvæ of the bees
contained in the full box or boxes.
"No pearly loads they bear; but o'er the field
Round flower and fruit the lithe proboscis wield.
From meal-tipp'd anthers steal the lacquer'd crown,
And brush from rind or leaf the silvery down.
Nay oft, when threaten'd storms or drizzling rain.
Close in their walls, th' impatient hosts detain,
E'en from the yellow hoard's nectareous rill,
Their tubes secerning can a stream distil,
Clear and untinctur'd as the fountain wave,
That glides, slow trickling, thro' the crevic'd cave.
But, as that welling wave, around the stone,
In rings concentric, wreathes its sparry zone.
So filter'd thro' yon flutterer's folded mail.
Clings the cool'd +wax+, and hardens to a scale."
+Evans.+
The observations of +Mr. John Hunter+ tended to confirm this view of
the matter; still more so, those of +M. Huber+ and +Son+. In order
to determine the point with greater precision, Huber instituted many
experiments. He lodged a recent swarm in a straw-hive, leaving at its
disposal only a sufficiency of honey and water for its consumption, and
preventing it from going beyond the precincts of a room, so closed as to
admit only a renewal of the air. At the end of five days as many cakes
of beautifully white, though very fragile wax, were suspended from the
roof; the honey had totally disappeared. Still however, as there was a
possibility that the thighs and stomachs of the bees might have conveyed
pollen from the parent hive, he withdrew these five combs, and replaced
the bees in the hive with a fresh supply of honey and water; they renewed
their toil with unabated industry, and soon fabricated new combs: these
last were taken from them; when the patient and indefatigable insects
commenced a third structure of comb. Five times in succession were their
works thus completed and removed, although during the whole of this
period they were fed merely with honey and water, and could not possibly
have had access to farina.
These experiments, so uniform in their results, give indubitable validity
to the fact,--that honey, through the organic intervention of bees, may
be converted into wax. A contrary experiment was made, by abundantly
supplying a hive with fruit and pollen only: but during eight days
confinement the bees produced no wax whatever, nor exhibited any plates
under their abdominal rings; no combs were formed, nor was an atom of
farina touched,--a clear proof that farina supplies neither wax nor
sustenance to adult bees. The improbability of this indeed is evinced by
its abundance in hives whose tenants have died of famine. And as to its
being the constituent of wax, +Reaumur+ calculated that a well stocked
hive might collect at least 100 pounds of pollen in a season, whereas the
weight of wax fabricated in the same time would not exceed two pounds.
Experiments have proved the excellence of sugar as a substitute for
honey, and in some instances its superiority for the formation of wax.
It might otherwise have been supposed that bees might form comb from
some particles of wax accidentally present in the honey, and that these
afforded the pabulum for this secretion. To prove therefore that the
saccharine principle alone enabled the bees to produce wax, being still
confined, they were supplied with a syrup made with Canary-sugar and
water, and at the same time comparative experiments were made in another
hive, where the bees were fed on honey and water. The syrup-fed bees
produced wax sooner and more abundantly than the honey-fed bees. Another
fact was also incontrovertibly elicited; namely, that in the old hives
the honey is warehoused, and that in the new ones it is consumed and
transmuted into wax.
The experiments of +Huber+ have been confirmed by those of +M. Blondelu+,
of Noyau, who addressed a memoir upon this subject to the Society of
Agriculture at Paris, in May 1812. +Huish+ has critically examined these
experiments of Huber, but without being convinced by them: for having
observed pollen on the thighs of bees when swarming, and upon dissection,
in their stomachs also, he considers that pollen, elaborated in the
second stomach of the bee, "contains in itself the principle of wax."
Were this the case, what a store of pollen must the bees have reserved,
in Huber's experiments, wherein they formed five successive sets of comb,
without access to fresh pollen! The pollen or bee-bread, which Huish
discovered on the thighs and in the stomachs of some of his bees, was
most likely intended for larva-food; they were probably bees that had
been abroad, and joined the swarm on their passage home, before they
had deposited their freight in the parent hive. With this pollen (or
ambrosia, as it has been called), after conversion into a sort of whitish
jelly by the action of the bee's stomach, where it is probably mixed with
honey, and then regurgitated, the young brood, immediately upon their
exclusion and until their change into nymphs, are fed by the nursing-bees
several times a day. The opinion that pollen is the prime constituent of
wax was held by +Buffon+, and remains uncontradicted in an edition of
his Works so late as 1821. +Arthur Dobbs+, Esq., in the Philosophical
Transactions for 1752, instead of considering wax as digested pollen
discharged from the stomach of the bee, regards it as being emitted _per
annum_; and as he speaks of its discharge in husks or shells, doubtless
he saw it in that form, which it is now known to assume when moulded upon
the body of the bee. Indeed he says that he has had swarming bees alight
upon his hand, and drop warm wax upon it. Its being secreted only by the
under side of the belly might easily deceive, and lead him to regard it
as alvine excrement.
I will here subjoin some more proofs of the non-identity of wax and
pollen. So long ago as 1768, the +Lusatian Society+ (called _Société des
Abeilles_, founded at little Bautzen, a village in Upper Lusatia, under
the auspices of the Elector of Saxony,) knew that wax was not discharged
from the mouths of bees, but was secreted in thin scales among their
abdominal rings or segments. About 1774, +Mr. Thorley+ caught a bee just
entering its hive, and found, among the plaits of its belly, no less
than six pieces or scales of solid wax, perfectly white and transparent,
and he oftentimes saw wax in the same situation. +M. Duchet+, in his
_Culture des Abeilles_, quoted by +Wildman+ in 1778, declares that wax
is formed of honey; and relates in proof of it, that he has seen a
broken comb of an overset hive, which was repaired during bad weather,
when the bees could not acquire any other material. This statement of
Duchet corresponds with my own observation, as stated in page 357, but
is not so conclusive. In Duchet's instance there might have been other
materials in the hive besides honey; whereas in my case the bees had
access to no materials whatever, excepting the sugared ale and the honey
which they had conveyed from the parent hive, the swarm having been just
hived. +Wildman+, in his Treatise on the Management of Bees, states his
having seen pieces of wax, like fish scales, on the hive floor of a
fresh swarmed colony, part of which he thinks must at least have been
formed upon the body of the bee; some flakes might have fallen from the
combs then constructing, but there were many pieces among them which
were concave on one side and convex on the other, as if moulded on the
insect's belly. Flakes were likewise seen, hanging loose, between the
abdominal scales of the bees. In 1792, +Mr. John Hunter+, apparently
unacquainted with antecedent conjectures, detected the genuine reservoir
of wax under the bee's belly. He considered wax as an external secretion
of oil, formed and moulded between the abdominal scales of the insect.
+Dr. Evans+ confirms the testimony of Wildman and Hunter, having been an
eye-witness to the formation of wax into flakes. "One or more bees,"
he remarks, "may be often seen before the door of the hive, supporting
themselves by their two fore-feet, fluttering their wings, and agitating
the hind parts of their bodies. They are then evidently moulding the
wax between their abdominal scales, the motion of the wings serving to
preserve their balance, and as a signal for their companions within to
come and carry off the falling flakes." In the Philosophical Transactions
for 1807, +Mr. Knight+ states that there is no such secretory process;
that the wax is laid on the scales of the abdomen for the convenience of
carriage, and to receive warmth preparatory to cell-building.
To complete the evidence however, to me so irresistible, in favour of
the wax-secreting faculty of the bee's body, I observe finally, that
in 1793, M. Huber's observations led him to the same conclusion as Mr.
Hunter's, relative to the nature of the laminæ under the abdominal
scales: but Huber slumbered not there, he prosecuted the inquiry more
successfully than any preceding naturalist, and at length demonstrated
the secreting organs which had eluded the scrutiny of Swammerdam, Hunter,
and other acute anatomists. He found that these laminæ were contained in
distinct receptacles, on each side of the middle process of the scales;
he examined with great care the form and structure of these secreting
cavities, which are peculiar to working bees. Each working bee has
eight of these organs, sacklets or small compartments. Their general
shape is an irregular pentagon, and the plates of wax, being moulded in
them, exhibit accordingly the same form. A perforation of their lining
membrane on the side next to the abdomen, started a jet of transparent
fluid, which congealed on cooling; in this state it resembled wax, and
became again fluid on the application of heat. Comparative experiments
were made with the substance contained in the pouches and with the wax
of fresh combs: a great similarity between these two substances was
discerned; the latter appeared somewhat more compound, having probably
received some additional ingredient, while employed as the material for
building. The secreting function of the membrane on the inner surface
of these cavities, was further evinced, by a more minute examination of
its structure, which exhibited a number of folds, forming an hexagonal
net-work, analogous to the inner coat of the second stomach of ruminating
quadrupeds. Huber does not appear to have known the observations either
of Duchet or of Wildman on this subject, although they were made long
prior to Mr. Hunter's; for he quotes only from the latter.
When combs are wanted, bees fill their crops with honey, and retaining
it in them, hang together in a cluster from the top of the hive, and
remain inactive about twenty-four hours. During this time the wax is
secreted, and may be seen in laminæ, under the abdominal scales, whence
it is removed by the hind legs of the bee, and transferred to the fore
legs; from them it is taken by the jaws, and after being masticated as
described in Chap, XXXIV, page 347, the fabrication of comb commences.
"To see the wax-pockets in the hive-bee, you must press the abdomen,
so as to cause its distention; you will then find, on each of the four
intermediate ventral segments, separated by the carina or elevated
central part, two trapeziform whitish pockets, of a soft membranaceous
texture: on these the laminæ of wax are formed, in different states, more
or less perceptible[AB]."
[Footnote AB: Kirby and Spence.]
+Messrs. Huber+ and +Son+ ascertained that the office of collecting
honey, for the elaboration of wax, is filled by a particular description
of bees or labourers, to which they have given the name of _wax-workers_.
These bees are susceptible of an increase in size, as is evident from
the state of their stomachs, when quite full of honey. Dissection has
shown that their stomachs are more capacious than those of the bees that
are differently occupied. Bees not possessed of this expanding stomach,
gather no more honey than is necessary to supply the immediate wants of
themselves and their companions, with whom they readily share it: these
are called _nursing-bees_, their principal duty being to attend the
eggs and larvæ. The task of storing the hive with provisions devolves
upon the wax-workers, who, when not occupied in the construction of
comb, disgorge their honey into those cells which are intended for its
reception. By marking the bees, it was found that they never encroached
upon each other's employment: this strict adjustment of duty is the
more remarkable, since the power of producing wax is common both to the
nursing- and wax-working bees, a small quantity of wax being really found
in the receptacles of the nursing-bees.
In the foregoing experiments for ascertaining the sources of wax, the
bees had borne their confinement without evincing the least impatience;
but on another occasion, when shut up with a brood of eggs and larvæ,
and without pollen, though honey was copiously supplied, they manifested
uneasiness and rage at their imprisonment. Fearing the consequence of
this state of tumult being prolonged, Huber allowed them to escape in the
evening, when too late to collect provisions; the bees soon returned
home. At the end of five days, during which this experiment was tried,
the hive was examined:--the larvæ had perished, and the jelly that
surrounded them on their introduction into the hive had disappeared.
The same bees were then supplied with a fresh brood, together with some
comb containing pollen: very different indeed was their behaviour with
this outfit; they eagerly seized the pollen and conveyed it to the
young; order and prosperity were re-established in the colony; the larvæ
underwent the usual transformations; royal cells were completed and
closed with wax, and the bees showed no desire to quit their habitation.
These experiments afford indisputable evidence of the origin of wax and
the destination of pollen.
Though the wax of honey and brood-comb be an original secretion from the
body of the bee, wax is also considered by some as a vegetable substance
existing abundantly in nature. According to +Proust+, it forms the
silvery down on the leaves, flowers and fruit of many plants, and resides
likewise in the feculæ of others. +Dr. Darwin+, in his _Phytologia_,
supposes that wax is secreted to glaze over the fecundating dust of the
anthers, and prevent its premature explosion from excessive moisture: to
an unseasonable dispersion of anther-dust he ascribes the failure of
orchard and corn crops in summers of extreme humidity. The wax-tree of
Louisiana[AC] (_Myrica cerifera_) contains immense quantities of wax.
In this respect there appears an identity betwixt animal and vegetable
secretion, which may be viewed as indicative of simplicity in the
structure of the bee: a still simpler organization exists in the aphis,
which extracts the saccharine juices from the leaves and bark of trees,
and expels them again nearly unchanged[AD].

[Footnote AD: _Vide_ Part I. Chap. 5.]
CHAPTER XXXVI.
POLLEN.
+_Pollen_+ and _Farina_, in the language of Botanists, are terms applied
to the powdery particles discharged by the anthers of flowers in warm dry
weather, and which hang about the stamina. The colour, as well as the
structure of pollen, varies in different plants. Its use, in fecundating
the germens of flowers, is well known: the services of bees, towards
that end, will be noticed in a separate chapter. The sixth volume of the
Linnæan Transactions contains an interesting paper upon this substance,
from the pen of +Mr. Luke Howard+.
_Pollen has a capsular structure_, varying its shape in different
flowers, insomuch as to be a popular object for the microscope. Each
grain consists commonly of a membranous bag, which, when it has come
to maturity, bursts on the application of moisture: this bursting is
naturally effected by the honey-like exudation of the stigma; but if
extraneous moisture accomplish it prematurely, the pollen is rendered
useless for the purpose of fructification. Whenever moistened, the bag
explodes with great force, and discharges a subtle vapour or essence,
which, when released by the peculiar moisture of the stigma, performs
effectually its final purpose.
This substance was once erroneously supposed to be the prime constituent
of wax; but the experiments of +Hunter+ and +Huber+ have proved that wax
is a secretion from the bodies of wax-working bees[AE], and that the
principal purpose of pollen is to nourish the embryo-bees; (it has been
called the ambrosia of the hive). Huber was the first who suggested this
idea, and it well accords with what we observe among other parts of the
animal kingdom;--birds, for instance, feed their young with different
food from what they take themselves. Mr. Hunter examined the stomachs of
the maggot-bees, and found farina in all, but not a particle of honey
in any of them. Huber considers the pollen as undergoing a peculiar
elaboration in the stomachs of the nursing-bees, to be fitted for the
nutriment of the larvæ.
[Footnote AE: _Vide_ Chap. XXXV.]
"In spring," says +Dr. Evans+, "which may be called the bee's first
_carrying_ season, scarcely one of the labourers is seen returning to the
hive, without a little ball or pellet of farina, on each of its hinder
legs. These balls are invariably of the same colour as the anther-dust
of the flowers then in bloom, the different tints of yellow, as pale,
greenish or deep orange, being most prevalent." The bees may frequently
be observed to roll their bodies on the flower, and then, brushing off
the pollen which adheres to them, with their feet, form it into two
masses, which they dispose of in the usual way. In very dry weather,
when probably the particles of pollen cannot be made to cohere, I have
often seen them return home so completely enveloped by it, as to give
them the appearance of a different species of bee. The anther-dust, thus
collected, is conveyed to the interior of the hive, and there brushed off
by the collector or her companions. +Reaumur+ and others have observed,
that _bees prefer the morning for collecting this substance_, most
probably that the dew may assist them in the moulding of their little
balls. "I have seen them abroad," says Reaumur, "gathering farina before
it was light;" they continue thus occupied till about ten o'clock.
"Brush'd from each anther's crown, the mealy gold.
With morning dew, the light fang'd artists mould.
Fill with the foodful load their hollow'd thigh,
And to their nurslings bear the rich supply."
+Evans.+
This is their practice during the warmer months; but in April and May,
and at the settlement of a recent swarm, they carry pollen throughout
the day; but even in these instances, the collection is made in places
most likely to furnish the requisite moisture for moulding the pellets,
namely, in shady and sometimes in very distant places.
When a bee has completed her loading, she returns to the hive, _part_ of
her cargo _is instantly devoured_ by the nursing-bees, to be regurgitated
for the use of the larvæ, and _another part is stored_ in cells for
future exigencies, _in the following manner_. The bee, while seeking a
fit cell for her freight, makes a noise with her wings, as if to summon
her fellow-citizens round her; she then fixes her two middle and her two
hind legs upon the edge of the cell which she has selected, and curving
her body, seizes the farina with her fore legs, and makes it drop into
the cell: thus freed from her burthen, she hurries off to collect again.
Another bee immediately packs the pollen, and kneads and works it down
into the bottom of the cell, probably mixing a little honey with it,
judging from the moist state in which she leaves it; an air-tight coating
of varnish finishes this storing of pollen.
From the uniform colour of each collection, it is reasonable to suppose
that _the bee never visits more than one species of flower on the same
journey;_ this was the opinion of +Aristotle+, and the generality
of modern observers have confirmed it. +Reaumur+, however, supposed
that the bee ranged from flowers of one species to those of another
indiscriminately. +Mr. Arthur Dobbs+, in the Philosophical Transactions
for 1752, states that he has repeatedly followed bees when collecting
pollen; and that whatever flowers they first alighted upon decided
their choice for that excursion, all other species being passed over
unregarded: +Butler+ had previously asserted the same thing. Here we see
the operation of a discriminating instinct, which in the first place
leads the insect to make an aggregation of homogeneous particles, which
of course form the closest cohesion; and in the next place prevents the
multiplication of hybrid plants. This remark was made by +Sprengel+, who
has confirmed the observations of Dobbs, Butler, and others. The bees,
which Reaumur observed to visit flowers of different species, might have
been in quest of honey as well as of pollen.
CHAPTER XXXVII.
PROPOLIS.
Besides the honey and pollen which are gathered by bees, they collect
a resinous substance, that is very tenacious, semitransparent, and
which gives out a balsamic odour, somewhat resembling that of storax.
In the mass, it is of a reddish brown colour; when broken, its colour
approaches that of wax. Dissolved in spirit of wine or oil of turpentine,
it imparts, as varnish, a golden colour to silver, tin, and other white
polished metals. Being supposed to possess medicinal virtue, it was
formerly kept in the shop of the apothecary. According to Vauquelin,
propolis consists of one part of wax and four of pure resin; in which
respect, and in its yielding the same acid, (the _benzoic_,) it resembles
balsam Peru. It also contains some aromatic principles.
With propolis, bees attach the combs to the roof and sides of their
dwelling, stop crevices, fasten the hives or boxes to the floors and
roofs, strengthen the weak places of their domicile, and varnish the
cell-work of their combs. The chapter on Instincts details the modes in
which bees employ it for their protection against intruders into their
hives. From its being used for the firm attachment of combs to the roofs
of hives, it must be the first matter collected by a recent swarm. The
term Propolis is derived from the Greek, and signifies 'before the
city,' bees having been observed to make use of it, in strengthening the
outworks of their city.
Reaumur was unable to discover its vegetable source. It is generally
supposed to be gathered from the resinous exudations of the poplar,
alder, birch, and willow; according to Riem, from pines and other trees
of the fir tribe; though some authors have alleged that bees can produce
it where no such trees are near them, and that turpentine and other
resins have been disregarded when laid before them. A recent experiment
of Huber has solved this question: he planted in spring some branches of
the wild poplar, before the leaves were developed, and placed them in
pots near his apiary: the bees alighting on them separated the folds of
the largest buds with their forceps, extracted the varnish in threads,
and loaded with it, first one thigh and then the other; for they convey
it like pollen, transferring it by the first pair of legs to the second,
by which it is lodged in the hollow of the third. Huber examined the
chemical properties of this varnish, and identified it with the propolis
which fastens the combs to the hives.
With respect to the absence of fir-trees, &c. in the neighbourhood of
the hives, it is to be recollected, in the first place, that _bees will
fly about three miles_ (some say five,) for what they may want: +Huber+
_thinks that the radius of the circle they traverse does not exceed half
a league_, yet says that the question is undecided. In the second place,
that a balsamic and tenacious secretion is found upon the buds of several
plants and trees, which are often crowded with these insects; such for
instance as the tacamahac, horse-chesnut, and hollyhock. Dr. Evans says
that he has been an eye-witness of their collecting the balsamic varnish
which coats the young blossom buds of the hollyhock, and has seen them
rest at least ten minutes on the same bud, moulding the balsam with their
fore-feet and transferring it to the hinder legs, as above stated. When
finally moulded, the pellets of propolis are of a lenticular form.
"With merry hum the Willow's copse they scale,
The fir's dark pyramid, or Poplar pale,
Scoop from the Alder's leaf its oozy flood,
Or strip the Chesnut's resin-coated bud,
Skim the light tear that tips Narcissus' ray.
Or round the Hollyhock's hoar fragrance play.
Soon temper'd to their will through eve's low beam,
And link'd in airy bands the viscous stream.
They waft their nut-brown loads exulting home,
That form a fret-work for the future comb,
Caulk every chink where rushing winds may roar,
And seal their circling ramparts to the floor."
+Evans.+
As to the bees refusing resinous substances, when presented to them,
as substitutes for propolis, +Mr. Knight+ has assured us, in the
Philosophical Transactions, that this is not the fact; as he had seen
them carry off a composition of wax and turpentine, which had been laid
over the decorticated parts of his trees.
The bees blend this substance with wax in different proportions, as
occasion may require. Among the ancients, it bore different names,
according to the quantity of wax it contained. Virgil made this
distinction, though +Mr. Martin+ conceives that his _narcissi lachrymæ_,
_cera_ [cum quâ]--"spiramenta tenuia linunt,"--and _gluten_, all mean
the same thing: this is probably a mistake. It seems much more likely
that +Virgil+ should mean _metys_, _pissoceron_ and _propolis_, the
three names by which +Pliny+ says that the varieties of propolis were
distinguished in his time.
I have before alluded to the fortification of the weak places of hives
with propolis. M. Reaumur, whose hives consisted of wooden frames and
panes of glass, wishing to put this talent of the bees to the test,
carelessly fastened the glass of a hive with paper and paste, before
putting in a swarm; the bees soon discovered the weakness of his
paste-work, and indignantly gnawing to pieces this feeble fence, secured
the glass with their own cement.
I have already observed, that _the sage bee_ chooses the morning for
collecting pollen, on account of the dew's enabling her to compress
it better; but, as moisture would render propolis less coherent, she
_gathers this substance when the day is somewhat advanced_, and when
the warmth of the sun has imparted to it softness and pliancy. These
qualities are however soon lost, after it has been detached from the
secreting surfaces, and exposed to the oxygenizing power of the air. So
rapid is this hardening process, that the bees which store it, oftentimes
find some difficulty in tearing it with their jaws from the thighs of its
collectors.
CHAPTER XXXVIII.
IMPORTANCE OF BEES TO THE FRUCTIFICATION OF FLOWERS.
Honey is regarded by modern naturalists as of no other use to plants but
to allure insects, which, by visiting the nectaries of their flowers
to procure it, become instrumental to their fertilization, either by
scattering the dust of the stamens upon the stigmata of the same flower,
or by carrying it from those which produce only male blossoms to those
that bear female ones, and thereby rendering the latter fertile.
No class of insects renders so much service in this way as _bees_; they
_have_ however _been accused of injuring vegetables_, in three ways: 1st,
by purloining for their combs the wax which defends the prolific dust of
the anthers from rain; 2ndly, by carrying off the dust itself, as food
for their young larvæ; and 3dly, by devouring the honey of the nectaries,
intended to nourish the vegetable organs of fructification[AF].
[Footnote AF: Darwin's _Phytologia_.]
In defence of his insect protegées, +Dr. Evans+ has observed:
"First, That the proportion of wax collected from the anthers is
probably very trifling, it being so readily and abundantly obtainable
from honey.
"Secondly, That for any depredations committed on the farina, they
amply compensate, by their inadvertent yet providential conveyance of
it, on their limbs and corslets, to the female organs of monoecious or
dioecious plants; whose impregnation must otherwise have depended on the
uncertain winds. This is exemplified in the practice of our gardeners,
who in early spring, before they dare expose their hotbeds to the open
air, and consequently to the access of insects, insure the fertility of
the cucumbers and melons, by shaking a male blossom over each female
flower. For the same purpose, and with the same success, a gentleman in
Shropshire substitutes a male blossom, in place of the female one, at the
top of his embryo cucumber, which instantly adheres, and falls off in due
time. To the same kind intrusion of insects we owe the numberless new
sorts of esculents and endless varieties of flowers in the parterre:
'Where Beauty plays
Her idle freaks; from family diffus'd
To family, as flies the father dust
The varied colours run.'
+Thomson+
"Thirdly, That in a great many instances, the honey-cups are completely
beyond the reach of the fructifying organs, and cannot possibly be
subservient to their use. Hence +Sir J. E. Smith+ _believes the honey
to be intended, by its scent, to allure these venial panders to the
flowers_, and thereby shows how highly he estimates their value to
vegetation. See his Introduction to Botany. In the same work, the author
observes that +Sprengel+ has ingeniously demonstrated, in some hundreds
of instances, how the corolla serves as an attraction to insects,
indicating by various marks, sometimes perhaps by its scent, where they
may find honey, and accommodating them with a convenient resting-place or
shelter while they extract it. This elegant and ingenious theory receives
confirmation from almost every flower we examine. Proud man is disposed
to think that
'Full many a flower is born to blush unseen,'
because he has not deigned to explore it; but we find that even the
beauties of the most sequestered wilderness are not made in vain. They
have myriads of admirers, attracted by their charms, and rewarded by
their treasures, which would be as useless as the gold of a miser, to the
plant itself, were they not the means of bringing insects about it."
Thus the bee, by settling upon and collecting honey from a thousand
different flowers, is thereby assisting the great purpose of vegetable
reproduction, at the same time that the loads she carries home enable
her to construct receptacles for the reproduction of her own race.
"For the due fertilization of the common _Barberry_, it is necessary that
its irritable stamens should be brought into contact with the pistil, by
the application of some stimulus to the base of the filament; but this
would never take place were not insects attracted, by the melliferous
glands of the flower, to insinuate themselves amongst the filaments,
and thus, while seeking their own food, unknowingly to fulfil the
intentions of Nature in another department." _In some cases the agency
of the hive-bee is inadequate to produce the required end; in these the
humble-bee is the operator:_ these alone, as Sprengel has observed, are
strong enough for instance, to force their way beneath the style-flag of
the _Iris Xiphium_, which in consequence is often barren. _Other insects
besides bees are instrumental in producing the same ends;_ indeed they
are necessary instruments: and hence according to the same naturalist,
in some places, where the particular insect required is not to be met
with, no fruit is formed upon the plant which is usually visited by it,
where it is indigenous; for he supposes that _some plants have particular
insects appropriated to them_. The American _Aristolochia Sipho_, though
it flowers plentifully, never forms fruit in our gardens, probably for
the reason just assigned. The _Date Palm_ affords a striking instance
of the necessity of extraneous intervention to perfect fructification;
male and female flowers are borne on separate trees, and unless the two
sorts be in the neighbourhood of each other, the fruit has no kernel and
is not proper for food. There was a tree of this kind, bearing female
flowers, at Berlin, for the fructification of which, a branch, with
male flowers upon it, was once sent by post from Leipsic, (20 German
miles,) and being suspended over some of the pistils, the tree afterwards
yielded fruit and seed in abundance. +Professor Willdenow+ has stated a
very curious circumstance, concerning the _Aristolochia Clematitis_. He
observes that the stamens and pistils of the flower are inclosed in its
globular base, the anthers being under the stigma, which thereby requires
the intervention of an insect, to convey the pollen to it. The _Tipula
pennicornis_ accomplishes this object; it enters the flower by its
tubular part, which is thickly lined with inflected hairs, so as readily
to admit the fly, but totally to prevent its release, till by the fading
of the corolla the hairs have fallen flat against its sides. Hence the
insect in struggling to effect its escape, brushes off the pollen and
applies it to the stigma, thereby accomplishing the fertilization of the
flower.
