The lord of the creation plumes himself upon his powers of invention,

and is proud to enumerate the various useful arts and machines to

which they have given birth, not aware that "He who teacheth man

knowledge" has instructed these despised insects to anticipate him

in many of them. The builders of Babel doubtless thought their

invention of turning earth into artificial stone, a very happy

discovery[33]; yet a little bee[34] had practised this art, using

indeed a different process, on a small scale, and the white ants on

a large one, ever since the world began. Man thinks that he stands

unrivalled as an architect, and that his buildings are without a

parallel among the works of the inferior orders of animals. He would

be of a different opinion did he attend to the history of insects:

he would find that many of them have been architects from time

immemorial; that they have had their houses divided into various

apartments, and containing staircases, gigantic arches, domes,

colonnades, and the like; nay, that even tunnels are excavated by

them so immense, compared with their own size, as to be twelve times

bigger than that projected by Mr. Dodd to be carried under the Thames

at Gravesend[35]. The modern fine lady, who prides herself on the

lustre and beauty of the scarlet hangings which adorn the stately

walls of her drawing-room, or the carpets that cover its floor,

fancying that nothing so rich and splendid was ever seen before,

and pitying her vulgar ancestors, who were doomed to unsightly

white-wash and rushes, is ignorant all the while, that before she or

her ancestors were in existence, and even before the boasted Tyrian

dye was discovered, a little insect had known how to hang the walls

of its cell with tapestry of a scarlet more brilliant than any her

rooms can exhibit[36]; and that others daily weave silken carpets,

both in tissue and texture infinitely superior to those she so much

admires. No female ornament is more prized and costly than lace, the

invention and fabrication of which seems the exclusive claim of the

softer sex. But even here they have been anticipated by these little

industrious creatures, who often defend their helpless chrysalis, by

a most singular covering, and as beautiful as singular, of lace[37].

Other arts have been equally forestalled by these creatures. What

vast importance is attached to the invention of paper! For near six

thousand years one of our commonest insects has known how to make

and apply it to its purposes[38]; and even pasteboard, superior

in substance and polish to any we can produce, is manufactured by

another[39]. We imagine that nothing short of human intellect can

be equal to the construction of a diving-bell or an air-pump--yet a

spider is in the daily habit of using the one, and, what is more, one

exactly similar in principle to ours, but more ingeniously contrived;

by means of which she resides unwetted in the bosom of the water,

and procures the necessary supplies of air by a much more simple

process than our alternating buckets[40]--and the caterpillar of

a little moth knows how to imitate the other, producing a vacuum,

when necessary for its purposes, without any piston besides its own

body[41]. If we think with wonder of the populous cities which have

employed the united labours of man for many ages to bring them to

their full extent, what shall we say to the white ants, which require

only a few months to build a metropolis capable of containing an

infinitely greater number of inhabitants than even imperial Nineveh,

Babylon, Rome, or Pekin, in all their glory?

That insects should thus have forestalled us in our inventions

ought to urge us to pay a closer attention to them and their ways

than we have hitherto done, since it is not at all improbable that

the result would be many useful hints for the improvement of our

arts and manufactures, and perhaps for some beneficial discoveries.

The painter might thus probably be furnished with more brilliant

pigments, the dyer with more delicate tints, and the artisan with a

new and improved set of tools. In this last respect insects deserve

particular notice. All their operations are performed with admirable

precision and dexterity; and though they do not usually vary the

mode, yet that mode is always the best that can be conceived for

attaining the end in view. The instruments also with which they

are provided are no less wonderful and various than the operations

themselves. They have their saws, and files, and augers, and gimlets,

and knives, and lancets, and scissors, and forceps, with many other

similar implements; several of which act in more than one capacity,

and with a complex and alternate motion to which we have not yet

attained in the use of our tools. Nor is the fact so extraordinary as

it may seem at first, since "He who is wise in heart and wonderful in

working" is the inventor and fabricator of the apparatus of insects;

which may be considered as a set of miniature patterns drawn for our

use by a Divine hand. I shall hereafter give you a more detailed

account of some of the most striking of these instruments; and if

you study insects in this view, you will be well repaid for all the

labour and attention you bestow upon them.

But a more important species of instruction than any hitherto

enumerated may be derived from entomological pursuits. If we attend

to the history and manners of insects, they will furnish us with

many useful lessons in Ethics, and from them we may learn to improve

ourselves in various virtues. We have indeed the inspired authority

of the wisest of mankind for studying them in this view, since he

himself wrote a treatise upon them, and sends his sluggard to one for

a lesson of wisdom[42]. And if we value diligence and indefatigable

industry; judgement, prudence, and foresight; economy and frugality;

if we look upon modesty and diffidence as female ornaments; if we

revere parental affection--of all these, and many more virtues,

insects in their various instincts exhibit several striking examples,

as you will see in the course of our correspondence.

With respect to religious instruction insects are far from

unprofitable; indeed in this view Entomology seems to possess

peculiar advantages above every other branch of Natural History.

In the larger animals, though we admire the consummate art and

wisdom manifested in their structure, and adore that Almighty

power and goodness which by a wonderful machinery, kept in motion

by the constant action and re-action of the great positive and

negative powers of Nature, maintains in full force the circulations

necessary to life, perception, and enjoyment; yet as there seems

no disproportion between the objects and the different operations

that are going on in them, and we see that they afford sufficient

space for the play of their systems, we do not experience the same

sensations of wonder and astonishment that strike us when we behold

similar operations carried on without interruption in animals

scarcely visible to the naked eye. That creatures, which in the scale

of being are next to non-entities, should be elaborated with so much

art and contrivance, have such a number of parts both internal and

external, all so highly finished and each so nicely calculated to

answer its end; that they should include in this evanescent form

such a variety of organs of perception and instruments of motion,

exceeding in number and peculiarity of structure those of other

animals; that their nervous and respiratory systems should be so

complex, their secretory and digestive vessels so various and

singular, their parts of generation so clearly developed, and that

these minims of nature should be endowed with instincts in many cases

superior to all our boasted powers of intellect--truly these wonders

and miracles declare to every one who attends to the subject, "The

hand that made us is divine." We are the work of a Being infinite in

power, in wisdom, and in goodness.

But no religious doctrine is more strongly established by the

history of insects than that of a superintending Providence. That

of the innumerable species of these beings, many of them beyond

conception fragile and exposed to dangers and enemies without end,

no link should be lost from the chain, but all be maintained in

those relative proportions necessary for the general good of the

system; that if one species for a while preponderate, and instead

of preserving seem to destroy, yet counterchecks should at the same

time be provided to reduce it within its due limits; and further,

that the operations of insects should be so directed and overruled as

to effect the purposes for which they were created and never exceed

their commission: nothing can furnish a stronger proof than this,

that an unseen hand holds the reins, now permitting one to prevail

and now another, as shall best promote certain wise ends; and saying

to each, "Hitherto shalt thou come and no further."

So complex is this mundane system, and so incessant the conflict

between its component parts, an observation which holds good

particularly with regard to insects, that if instead of being under

such control it were left to the agency of blind chance, the whole

must inevitably soon be deranged and go to ruin. Insects, in truth,

are a book in which whoever reads under proper impressions cannot

avoid looking from the effect to the cause, and acknowledging his

eternal power and godhead thus wonderfully displayed and irrefragably

demonstrated: and whoever beholds these works with the eyes of the

body, must be blind indeed if he cannot, and perverse indeed if

he will not, with the eye of the soul behold in all his glory the

Almighty Workman, and feel disposed, with every power of his nature,

to praise and magnify

"Him first, Him last, Him midst, Him without end."

And now having led you to the vestibule of an august temple, which in

its inmost sanctuary exhibits enshrined in glory the symbols of the

Divine Presence, I should invite you to enter and give a tongue to

the Hallelujahs, which every creature in its place, by working his

will with all its faculties, pours forth to its great Creator: but I

must first endeavour to remove, as I trust I shall effectually, those

objections to the study of these interesting beings which I alluded

to in the outset of this letter, and this shall be the aim of my next

address.

I am, &c.

LETTER II.

_OBJECTIONS ANSWERED._

In my last I gave you a general view of the science of Entomology,

and endeavoured to prove to you that it possesses attractions and

beauty sufficient to reward any student who may profess himself

its votary. I am now to consider it in a less alluring light, as a

pursuit attended by no small degree of obloquy, in consequence of

certain objections thought to be urged with great force against it.

To obviate these, and remove every scruple from your mind, shall be

the business of the present letter.

Two principal objections are usually alleged with great confidence

against the study and pursuit of insects. By some they are derided as

trifling and unimportant, and deemed an egregious waste of time and

talents; by others they are reprobated as unfeeling and cruel, and as

tending to harden the heart.

* * * * *

I. I shall begin with the first of these objections--that the

entomologist is a mere trifler. As for the silly outcry and abuse

of the ignorant vulgar, who are always ready to laugh at what they

do not understand, and because insects are minute objects conclude

that the study of them must be a childish pursuit, I shall not waste

words upon what I so cordially despise. But since even learned men

and philosophers, from a partial and prejudiced view of the subject,

having recourse to this common-place logic, are sometimes disposed

to regard all inquiry into these minutiæ of nature as useless and

idle, and the mark of a little mind; to remove such prejudice and

misconceptions I shall now dilate somewhat upon the subject of _Cui

bono?_

When we see many wise and learned men pay attention to any particular

department of science, we may naturally conclude that it is on

account of some profit and instruction which they foresee may be

derived from it; and therefore in defending Entomology I shall first

have recourse to the _Argumentum ad verecundiam_, and mention the

great names that have cultivated or recommended it.

We may begin the list with the first man that ever lived upon

the earth, for we are told that he gave a name to every living

creature[43], amongst which insects must be included; and to give an

appropriate name to an object necessarily requires some knowledge of

its distinguishing properties. Indeed one of the principal pleasures

and employments of the paradisiacal state was probably the study

of the various works of creation[44]. Before the fall the book of

nature was the Bible of man, in which he could read the perfections

and attributes of the invisible Godhead[45], and in it, as in a

mirror, behold an image of the things of the spiritual world. Moses

also appears to have been conversant with our little animals, and

to have studied them with some attention. This he has shown, not

only by being aware of the distinctions which separate the various

tribes of grasshoppers, crickets &c. (_Gryllus_, L.) into different

genera[46], but also by noticing the different direction of the

two anterior from the four posterior legs of insects; for, as he

speaks of them as going upon four legs[47], it is evident that he

considered the two anterior as arms. Solomon, the wisest of mankind,

made Natural History a peculiar object of study, and left treatises

behind him upon its various branches, in which _creeping things_ or

insects were not overlooked[48]; and a wiser than Solomon directs

our attention to natural productions, when he bids us _consider_ the

lilies of the field[49], teaching us that they are more worthy of our

notice than the most glorious works of man: he also not obscurely

intimates that insects are symbolical beings, when he speaks of

scorpions as synonymous with evil spirits[50]; thus giving into

our hands a clue for a more profitable mode of studying them, as

furnishing moral and spiritual instruction.

If to these scriptural authorities we add those of uninspired

writers, ancient and modern, the names of many worthies, celebrated

both for wisdom and virtue, may be produced. Aristotle among the

Greeks, and Pliny the elder among the Romans, may be denominated the

fathers of Natural History, as well as the greatest philosophers of

their day; yet both these made insects a principal object of their

attention: and in more recent times, if we look abroad, what names

greater than those of Redi, Malpighi, Vallisnieri, Swammerdam,

Leeuwenhoek, Reaumur, Linné, De Geer, Bonnet, and the Hubers? and

at home, what philosophers have done more honour to their country

and to human nature than Ray, Willughby, Lister, and Derham? Yet all

these made the study of insects one of their most favourite pursuits;

and, as if to prove that this study is not incompatible with the

highest flights of genius, we can add to the list the name of one of

the most sublime of our poets, Gray, who was very zealously devoted

to Entomology. As far therefore as names have weight, the above

enumeration seems sufficient to shelter the votaries of this pleasing

science from the charge of folly.

But we do not wish to rest our defence upon authorities alone; let

the voice of reason be heard, and our justification will be complete.

The entomologist, or, to speak more generally, the naturalist (for

on this question of _Cui bono?_ every student in all departments of

Natural History is concerned), if the following considerations be

allowed their due weight, may claim a much higher station amongst the

learned than has hitherto been conceded to him.

There are two principal avenues to knowledge--the study of words

and the study of things. Skill in the learned languages being often

necessary to enable us to acquire knowledge in the former way,

is usually considered as knowledge itself; so that no one asks

_Cui bono?_ when a person devotes himself to the study of verbal

criticism, and employs his time in correcting the errors that have

crept into the text of an ancient writer. Indeed it must be owned,

though perhaps too much stress is sometimes laid upon it, that this

is very useful to enable us to ascertain his true meaning. But after

all, words are but the arbitrary signs of ideas, and have no value

independent of those ideas, further than what arises from congruity

and harmony, the mind being dissatisfied when an idea is expressed

by inadequate words, and the ear offended when their collocation is

inharmonious. To account the mere knowledge of words, therefore, as

wisdom, is to mistake the cask for the wine, and the casket for the

gem. I say all this because knowledge of words is often extolled

beyond its just merits, and put for all wisdom; while knowledge of

things, especially of the productions of nature, is derided as if it

were mere folly. We should recollect that God hath condescended to

instruct us by both these ways, and therefore neither of them should

be depreciated. He hath set before us his word and his world. The

former is the great avenue to truth and knowledge by the study of

_words_, and, as being the immediate and authoritative revelation

of his will, is entitled to our _principal_ attention; the latter

leads us to the same conclusions, though less directly, by the study

of _things_, which stands next in rank to that of God's word, and

before that of any work of man. And whether we direct our eyes to the

planets rolling in their orbits, and endeavour to trace the laws by

which they are guided through the vast of space, whether we analyse

those powers and agents by which all the operations of nature are

performed, or whether we consider the various productions of this our

globe, from the mighty cedar to the microscopic mucor--from the giant

elephant to the invisible mite, still we are studying the works and

wonders of our God. The book, to whatever page we turn, is written

by the finger of him who created us; and in it, provided our minds

be rightly disposed, we may read his eternal verities. And the more

accurate and enlarged our knowledge of his works, the better shall

we be able to understand his word; and the more practised we are in

his word, the more readily shall we discern his truth in his works;

for, proceeding from the same great Author, they must, when rightly

interpreted, mutually explain and illustrate each other.

Who then shall dare maintain, unless he has the hardihood to deny

that God created them, that the study of insects and their ways is

trifling or unprofitable? Were they not arrayed in all their beauty,

and surrounded with all their wonders, and made so instrumental (as

I shall hereafter prove them to be) to our welfare, that we might

glorify and praise him for them? Why were insects made attractive, if

not, as Ray well expresses it, that they might ornament the universe

and be delightful objects of contemplation to man[51]? And is it not

clear, as Dr. Paley has observed, that the production of beauty was

as much in the Creator's mind in painting a butterfly or in studding

a beetle, as in giving symmetry to the human frame, or graceful

curves to its muscular covering[52]? And shall we think it beneath

us to study what he hath not thought it beneath him to adorn and

place on this great theatre of creation? Nay, shall we extol those

to the skies who bring together at a vast expense the most valuable

specimens of the arts, the paintings and statues of Italy and Greece,

all of which, however beautiful, as works of man, fall short of

perfection; and deride and upbraid those who collect, for the purpose

of admiring their beauty, the finished and perfect chef-d'œuvres of

a Divine artist? May we gaze with rapture unblamed upon an Apollo of

Belvedere, or Venus de Medicis, or upon the exquisite paintings of a

Raphael or a Titian, and yet when we behold with ecstasy sculptures

that are produced by the chisel of the Almighty, and the inimitable

tints laid on by his pencil, because an insect is the subject, be

exposed to jeers and ridicule?

But there is another reason, which in the present age renders the

study of Natural History an object of importance to every well-wisher

to the cause of Religion, who is desirous of exerting his faculties

in its defence. For as enthusiasm and false religion have endeavoured

to maintain their ground by a perversion of the text of _scripture_,

so also the patrons of infidelity and atheism have laboured hard to

establish their impiety by a perversion of the text of _nature_. To

refute the first of these adversaries of truth and sound religion,

it is necessary to be well acquainted with the _word_ of God; to

refute the second, requires an intimate knowledge of his _works_;

and no department can furnish him with more powerful arguments of

every kind than the world of insects--every one of which cries out

in an audible voice, There is a God--he is Almighty, all-wise,

all-good--his watchful providence is ever, and every where, at work

for the preservation of all things.

But since mankind in general are too apt to look chiefly at this

world, and to regard things as important or otherwise in proportion

as they are connected with sublunary interests, and promote our

present welfare, I shall proceed further to prove that the study of

insects may be productive of considerable utility, even in this view,

and may be regarded in some sort as a necessary or at least a very

useful concomitant of many arts and sciences.

The importance of insects to us both as sources of good or evil, I

shall endeavour to prove at large hereafter; but for the present,

taking this for granted, it necessarily follows that the study of

them must also be important. For when we suffer from them, if we do

not know the cause, how are we to apply a remedy that may diminish

or prevent their ravages? Ignorance in this respect often occasions

us to mistake our enemies for our friends, and our friends for our

enemies; so that when we think to do good we only do harm, destroying

the innocent and letting the guilty escape. Many such instances have

occurred. You know the orange-coloured fly of the wheat, and have

read the account of the damage done by this little insect to that

important grain; you are aware also that it is given in charge to

three little parasites to keep it within due limits; yet at first it

was the general opinion of unscientific men, that these destroyers

of our enemy were its parents, and the original source of all the

mischief[53]. Middleton, in his "_Agriculture of Middlesex_,"

speaking of the Plant-louse that is so injurious to the bean, tells

us that the lady-birds are supposed either to generate or to feed

upon them[54]. Had he been an entomologist, he would have been in no

doubt whether they were beneficial or injurious: on the contrary, he

would have recommended that they should be encouraged as friends

to man, since no insects are greater devourers of the Aphides. The

confounding of the apple Aphis (_A. lanigera, Myzoxyla?_[55]) that

has done such extensive injury to our orchards, with others, has led

to proceedings still more injurious. This is one of those species

from the skin of which transpires a white cottony secretion. Some

of the proprietors of orchards about Evesham, observing an insect

which secreted a similar substance upon the poplar, imagined that

from this tree the creature which they had found so noxious was

generated; and in consequence of this mistaken notion cut down all

their poplars[56]. The same indistinct ideas might have induced them

to fell all their larches and beeches, since they also are infested

by Aphides which transpire a similar substance. Had these persons

possessed any entomological knowledge, they would have examined and

compared the insects before they had formed their opinions, and being

convinced that the poplar and apple Aphis are distinct species, would

have saved their trees.
