ON BIO-GEOLOGY {1}

I am not sure that the subject of my address is rightly chosen. I

am not sure that I ought not to have postponed a question of mere

natural history, to speak to you as scientific men, on the questions

of life and death, which have been forced upon us by the awful

warning of an illustrious personage's illness; of preventible

disease, its frightful prevalency; of the 200,000 persons who are

said to have died of fever alone since the Prince Consort's death,

ten years ago; of the remedies; of drainage; of sewage disinfection

and utilisation; and of the assistance which you, as a body of

scientific men, can give to any effort towards saving the lives and

health of our fellow-citizens from those unseen poisons which lurk

like wild beasts couched in the jungle, ready to spring at any

moment on the unsuspecting, the innocent, the helpless. Of all this

I longed to speak; but I thought it best only to hint at it, and

leave the question to your common sense and your humanity; taking

for granted that your minds, like the minds of all right-minded

Englishmen, have been of late painfully awakened to its importance.

It seemed to me almost an impertinence to say more in a city of

whose local circumstances I know little or nothing. As an old

sanitary reformer, practical, as well as theoretical, I am but too

well aware of the difficulties which beset any complete scheme of

drainage, especially in an ancient city like this; where men are

paying the penalty of their predecessors' ignorance; and dwelling,

whether they choose or not, over fifteen centuries of accumulated

dirt.

And, therefore, taking for granted that there is energy and

intellect enough in Winchester to conquer these difficulties in due

time, I go on to ask you to consider, for a time, a subject which is

growing more and more important and interesting, a subject the study

of which will do much towards raising the field naturalist from a

mere collector of specimens--as he was twenty years ago--to a

philosopher elucidating some of the grandest problems. I mean the

infant science of Bio-geology--the science which treats of the

distribution of plants and animals over the globe, and the cause of

that distribution.

I doubt not that there are many here who know far more about the

subject than I; who are far better read than I am in the works of

Forbes, Darwin, Wallace, Hooker, Moritz Wagner, and the other

illustrious men who have written on it. But I may, perhaps, give a

few hints which will be of use to the younger members of this

Society, and will point out to them how to get a new relish for the

pursuit of field science.

Bio-geology, then, begins with asking every plant or animal you

meet, large or small, not merely--What is your name? That is the

collector and classifier's duty; and a most necessary duty it is,

and one to be performed with the most conscientious patience and

accuracy, so that a sound foundation may be built for future

speculations. But young naturalists should act not merely as

Nature's registrars and census-takers, but as her policemen and

gamekeepers; and ask everything they meet--How did you get there?

By what road did you come? What was your last place of abode? And

now you are here, how do you get your living? Are you and your

children thriving, like decent people who can take care of

themselves, or growing pauperised and degraded, and dying out? Not

that we have a fear of your becoming a dangerous class. Madame

Nature allows no dangerous classes, in the modern sense. She has,

doubtless for some wise reason, no mercy for the weak. She rewards

each organism according to its works; and if anything grows too weak

or stupid to take care of itself, she gives it its due deserts by

letting it die and disappear. So, you plant or you animal, are you

among the strong, the successful, the multiplying, the colonising?

Or are you among the weak, the failing, the dwindling, the doomed?

These questions may seem somewhat rude: but you may comfort

yourself by the thought that plants and animals, though they deserve

all kindness, all admiration, deserve no courtesy--at least in this

respect. For they are, one and all, wherever you find them,

vagrants and landlopers, intruders and conquerors, who have got

where they happen to be simply by the law of the strongest--

generally not without a little robbery and murder. They have no

right save that of possession; the same by which the puffin turns

out the old rabbits, eats the young ones, and then lays her eggs in

the rabbit-burrow--simply because she can.

Now, you will see at once that such a course of questioning will

call out a great many curious and interesting answers, if you can

only get the things to tell you their story; as you always may if

you will cross-examine them long enough; and will lead you into many

subjects beside mere botany or entomology. So various, indeed, are

the subjects which you will thus start, that I can only hint at them

now in the most cursory fashion.

At the outset you will soon find yourself involved in chemical and

meteorological questions; as, for instance, when you ask--How is it

that I find one flora on the sea-shore, another on the sandstone,

another on the chalk, and another on the peat-making gravelly

strata? The usual answer would be, I presume--if we could work it

out by twenty years' experiment, such as Mr. Lawes, of Rothampsted,

has been making on the growth of grasses and leguminous plants in

different soils and under different manures--the usual answer, I

say, would be--Because we plants want such and such mineral

constituents in our woody fibre; again, because we want a certain

amount of moisture at a certain period of the year: or, perhaps,

simply because the mechanical arrangement of the particles of a

certain soil happens to suit the shape of our roots and of their

stomata. Sometimes you will get an answer quickly enough; sometimes

not. If you ask, for instance, Asplenium viride how it contrives to

grow plentifully in the Craven of Yorkshire down to 600 or 800 feet

above the sea, while in Snowdon it dislikes growing lower than 2000

feet, and is not plentiful even there?--it will reply--Because in

the Craven I can get as much carbonic acid as I want from the

decomposing limestone; while on the Snowdon Silurian I get very

little; and I have to make it up by clinging to the mountain tops,

for the sake of the greater rainfall. But if you ask Polypodium

calcareum--How is it you choose only to grow on limestone, while

Polypodium Dryopteris, of which, I suspect, you are only a variety,

is ready to grow anywhere?--Polypodium calcareum will refuse, as

yet, to answer a word.

Again--I can only give you the merest string of hints--you will find

in your questionings that many plants and animals have no reason at

all to show why they should be in one place and not in another, save

the very sound reason for the latter which was suggested to me once

by a great naturalist. I was asking--Why don't I find such and such

a species in my parish, while it is plentiful a few miles off in

exactly the same soil?--and he answered--For the same reason that

you are not in America. Because you have not got there. Which

answer threw to me a flood of light on this whole science. Things

are often where they are, simply because they happen to have got

there, and not elsewhere. But they must have got there by some

means, and those means I want young naturalists to discover; at

least, to guess at.

A species, for instance--and I suspect it is a common case with

insects--may abound in a single spot, simply because, long years

ago, a single brood of eggs happened to hatch at a time when eggs of

other species, who would have competed against them for food, did

not hatch; and they may remain confined to that spot, though there

is plenty of food for them outside it, simply because they do not

increase fast enough to require to spread out in search of more

food. Thus I should explain a case which I heard of lately of

Anthocera trifolii, abundant for years in one corner of a certain

field, and only there; while there was just as much trefoil all

round for its larvae as there was in the selected spot. I can, I

say, only give hints: but they will suffice, I hope, to show the

path of thought into which I want young naturalists to turn their

minds.

Or, again, you will have to inquire whether the species has not been

prevented from spreading by some natural barrier. Mr. Wallace, whom

you all of course know, has shown in his "Malay Archipelago" that a

strait of deep sea can act as such a barrier between species.

Moritz Wagner has shown that, in the case of insects, a moderately-

broad river may divide two closely-allied species of beetles, or a

very narrow snow-range, two closely-allied species of moths.

Again, another cause, and a most common one, is: that the plants

cannot spread because they find the ground beyond them already

occupied by other plants, who will not tolerate a fresh mouth,

having only just enough to feed themselves. Take the case of

Saxifraga hypnoides and S. umbrosa, "London pride." They are two

especially strong species. They show that, S. hypnoides especially,

by their power of sporting, of diverging into varieties; they show

it equally by their power of thriving anywhere, if they can only get

there. They will grow both in my sandy garden, under a rainfall of

only 23 inches, more luxuriantly than in their native mountains

under a rainfall of 50 or 60 inches. Then how is it that S.

hypnoides cannot get down off the mountains; and that S. umbrosa,

though in Kerry it has got off the mountains and down to the sea-

level, exterminating, I suspect, many species in its progress, yet

cannot get across County Cork? The only answer is, I believe, that

both species are continually trying to go ahead; but that the other

plants already in front of them are too strong for them, and

massacre their infants as soon as born.

And this brings us to another curious question: the sudden and

abundant appearance of plants, like the foxglove and Epilobium

angustifolium, in spots where they have never been seen before. Are

there seeds, as some think, dormant in the ground; or are the seeds

which have germinated, fresh ones wafted thither by wind or

otherwise, and only able to germinate in that one spot because there

the soil is clear? General Monro, now famous for his unequalled

memoir on the bamboos, holds to the latter theory. He pointed out

to me that the Epilobium seeds, being feathered could travel with

the wind; that the plant always made its appearance first on new

banks, landslips, clearings, where it had nothing to compete

against; and that the foxglove did the same. True, and most

painfully true, in the case of thistles and groundsels: but

foxglove seeds, though minute, would hardly be carried by the wind

any more than those of the white clover, which comes up so

abundantly in drained fens. Adhuc sub judice lis est, and I wish

some young naturalists would work carefully at the solution; by

experiment, which is the most sure way to find out anything.

But in researches in this direction they will find puzzles enough.

I will give them one which I shall be most thankful to hear they

have solved within the next seven years--How is it that we find

certain plants, namely, the thrift and the scurvy grass, abundant on

the sea-shore and common on certain mountain-tops, but nowhere

between the two? Answer me that. For I have looked at the fact for

years--before, behind, sideways, upside down, and inside out--and I

cannot understand it.

But all these questions, and especially, I suspect, that last one,

ought to lead the young student up to the great and complex

question--How were these islands re-peopled with plants and animals,

after the long and wholesale catastrophe of the glacial epoch?

I presume you all know, and will agree, that the whole of these

islands, north of the Thames, save certain ice-clad mountain-tops,

were buried for long ages under an icy sea. From whence did

vegetable and animal life crawl back to the land, as it rose again;

and cover its mantle of glacial drift with fresh life and verdure?

Now let me give you a few prolegomena on this matter. You must

study the plants of course, species by species. Take Watson's

"Cybele Britannica" and Moore's "Cybele Hibernica;" and let--as Mr.

Matthew Arnold would say--"your thought play freely about them."

Look carefully, too, in the case of each species, at the note on its

distribution, which you will find appended in Bentham's "Handbook,"

and in Hooker's "Student's Flora." Get all the help you can, if you

wish to work the subject out, from foreign botanists, both European

and American; and I think that, on the whole, you will come to some

such theory as this for a general starling platform. We do not owe

our flora--I must keep to the flora just now--to so many different

regions, or types, as Mr. Watson conceives, but to three, namely, an

European or Germanic flora, from the south-east; an Atlantic flora,

from the south-east; a Northern flora, from the north. These three

invaded us after the glacial epoch; and our general flora is their

result.

But this will cause you much trouble. Before you go a step farther

you will have to eliminate from all your calculations most of the

plants which Watson calls glareal, i.e. found in cultivated ground

about habitations. And what their limit may be I think we never

shall know. But of this we may be sure; that just as invading

armies always bring with them, in forage or otherwise, some plants

from their own country--just as the Cossacks, in 1815, brought more

than one Russian plant through Germany into France--just as you have

already a crop of North German plants upon the battle-fields of

France--thus do conquering races bring new plants. The Romans,

during their 300 or 400 years of occupation and civilisation, must

have brought more species, I believe, than I dare mention. I

suspect them of having brought, not merely the common hedge elm of

the south, not merely the three species of nettle, but all our red

poppies, and a great number of the weeds which are common in our

cornfields; and when we add to them the plants which may have been

brought by returning crusaders and pilgrims; by monks from every

part of Europe, by Flemings or other dealers in foreign wool--we

have to cut a huge cantle out of our indigenous flora: only, having

no records, we hardly know where and what to cut out; and can only,

we elder ones, recommend the subject to the notice of the younger

botanists, that they may work it out after our work is done.

Of course these plants introduced by man, if they are cut out, must

be cut out of only one of the floras, namely, the European; for

they, probably, came from the south-east, by whatever means they

came.

That European flora invaded us, I presume, immediately after the

glacial epoch, at a time when France and England were united, and

the German Ocean a mere network of rivers, which emptied into the

deep sea between Scotland and Scandinavia. And here I must add,

that endless questions of interest will arise to those who will

study, not merely the invasion of that truly European flora, but the

invasion of reptiles, insects, and birds, especially birds of

passage, which must have followed it as soon as the land was

sufficiently covered with vegetation to support life. Whole volumes

remain to be written on this subject. I trust that some of your

younger members may live to write one of them. The way to begin

will be; to compare the flora and fauna of this part of England very

carefully with that of the southern and eastern counties; and then

to compare them again with the fauna and flora of France, Belgium,

and Holland.

As for the Atlantic flora, you will have to decide for yourselves

whether you accept or not the theory of a sunken Atlantic continent.

I confess that all objections to that theory, however astounding it

may seem, are outweighed in my mind by a host of facts which I can

explain by no other theory. But you must judge for yourselves; and

to do so you must study carefully the distribution of heaths both in

Europe and at the Cape, and their non-appearance beyond the Ural

Mountains, and in America, save in Labrador, where the common ling,

an older and less specialised form, exists. You must consider, too,

the plants common to the Azores, Portugal, the West of England,

Ireland, and the Western Hebrides. In so doing young naturalists

will at least find proofs of a change in the distribution of land

and water, which will utterly astound them when they face it for the

first time.

As for the Northern flora, the question whence it came is puzzling

enough. It seems difficult to conceive how any plants could have

survived when Scotland was an archipelago in the same ice-covered

condition as Greenland is now; and we have no proof that there

existed after the glacial epoch any northern continent from which

the plants and animals could have come back to us. The species of

plants and animals common to Britain, Scandinavia, and North

America, must have spread in pre-glacial times when a continent

joining them did exist.

But some light has been thrown on this question by an article, as

charming as it is able, on "The Physics of the Arctic Ice," by Dr.

Brown of Campster. You will find it in the "Quarterly Journal of

the Geological Society" for February, 1870. He shows there that

even in Greenland peaks and crags are left free enough from ice to

support a vegetation of between three hundred or four hundred

species of flowering plants; and, therefore, he well says, we must

be careful to avoid concluding that the plant and animal life on the

dreary shores or mountain-tops of the old glacial Scotland was poor.

The same would hold good of our mountains; and, if so, we may look

with respect, even awe, on the Alpine plants of Wales, Scotland, and

the Lake mountains, as organisms, stunted it may be, and even

degraded by their long battle with the elements, but venerable from

their age, historic from their endurance. Relics of an older

temperate world, they have lived through thousands of centuries of

frost and fog, to sun themselves in a temperate climate once more.

I can never pick one of them without a tinge of shame; and to

exterminate one of them is to destroy, for the mere pleasure of

collecting, the last of a family which God has taken the trouble to

preserve for thousands of centuries.

I trust that these hints--for I can call them nothing more--will at

least awaken any young naturalist who has hitherto only collected

natural objects, to study the really important and interesting

question--How did these things get here?

Now hence arise questions which may puzzle the mind of a Hampshire

naturalist. You have in this neighbourhood, as you well know, two,

or rather three, soils, each carrying its peculiar vegetation.

First, you have the clay lying on the chalk, and carrying vast

woodlands, seemingly primeval. Next, you have the chalk, with its

peculiar, delicate, and often fragrant crop of lime-loving plants;

and next, you have the poor sands and clays of the New Forest basin,

saturated with iron, and therefore carrying a moorland or peat-

loving vegetation, in many respects quite different from the others.

And this moorland soil, and this vegetation, with a few singular

exceptions, repeats itself, as I daresay you know, in the north of

the county, in the Bagshot basin, as it is called--the moors of

Aldershot, Hartford Bridge, and Windsor Forest.

Now what a variety of interesting questions are opened up by these

simple facts. How did these three floras get each to its present

place? Where did each come from? How did it get past or through

the other, till each set of plants, after long internecine

competition, settled itself down in the sheet of land most congenial

to it? And when did each come hither? Which is the oldest? Will

any one tell me whether the healthy floras of the moors, or the

thymy flora of the chalk downs, were the earlier inhabitants of

these isles? To these questions I cannot get any answer; and they

cannot be answered without, first--a very careful study of the range

of each species of plant on the continent of Europe; and next,

without careful study of those stupendous changes in the shape of

this island which have taken place at a very late geological epoch.

The composition of the flora of our moorlands is as yet to me an

utter puzzle. We have Lycopodiums--three species--enormously

ancient forms which have survived the age of ice: but did they

crawl downward hither from the northern mountains or upward hither

from the Pyrenees? We have the beautiful bog asphodel again--an

enormously ancient form; for it is, strange to say, common to North

America and to Northern Europe, but does not enter Asia--almost an

unique instance. It must, surely, have come from the north; and

points--as do many species of plants and animals--to the time when

North Europe and North America were joined. We have, sparingly, in

North Hampshire, though, strangely, not on the Bagshot moors, the

Common or Northern Butterwort (Pinguicula vulgaris); and also, in

the south, the New Forest part of the county, the delicate little

Pinguicula lusitanica, the only species now found in Devon and

Cornwall, marking the New Forest as the extreme eastern limit of the

Atlantic flora. We have again the heaths, which, as I have just

said, are found neither in America nor in Asia, and must, I believe,

have come from some south-western land long since submerged beneath

the sea. But more, we have in the New Forest two plants which are

members of the South Europe, or properly, the Atlantic flora; which

must have come from the south and south-east; and which are found in

no other spots in these islands. I mean the lovely Gladiolus, which

grows abundantly under the ferns near Lyndhurst, certainly wild, but

it does not approach England elsewhere nearer than the Loire and the

Rhine; and next, that delicate orchid, the Spiranthes aestivalis,

which is known only in a bog near Lyndhurst and in the Channel

Islands, while on the Continent it extends from Southern Europe all

through France. Now, what do these two plants mark? They give us a

point in botany, though not in time, to determine when the south of

England was parted from the opposite shores of France; and whenever

that was, it was just after the Gladiolus and Spiranthes got hither.

Two little colonies of these lovely flowers arrived just before

their retreat was cut off. They found the country already occupied

with other plants; and, not being reinforced by fresh colonists from

the south, have not been able to spread farther north than

Lyndhurst. Thus, in the New Forest, and, I may say in the Bagshot

moors, you find plants which you do not expect, and do not find

plants which you do expect; and you are, or ought to be, puzzled,

and I hope also interested, and stirred up to find out more.

I spoke just now of the time when England was joined to France, as

bearing on Hampshire botany. It bears no less on Hampshire zoology.

In insects, for instance, the presence of the purple emperor and the

white admiral in our Hampshire woods, as well as the abundance of

the great stag-beetle, point to a time when the two countries were

joined, at least as far west as Hampshire; while the absence of

these insects farther to the westward shows that the countries, if

ever joined, were already parted; and that those insects have not

yet had time to spread westward. The presence of these two

butterflies, and partly of the stag-beetle, along the south-east

coast of England as far as the primeval forests of South

Lincolnshire, points, as do a hundred other facts, to a time when

the Straits of Dover either did not exist, or were the bed of a

river running from the west; and when, as I told you just now, all

the rivers which now run into the German Ocean, from the Humber on

the west to the Elbe on the east, discharged themselves into the sea

between Scotland and Norway, after wandering through a vast lowland,

covered with countless herds of mammoth, rhinoceros, gigantic ox,

and other mammals now extinct; while the birds, as far as we know,

the insects, the fresh-water fish, and even, as my friend Mr. Brady

has proved, the Entomostraca of the rivers, were the same in what is

now Holland as in what is now our Eastern counties. I could dwell

long on this matter. I could talk long about how certain species of

Lepidoptera--moths and butterflies--like Papilio Machaon and P.

Podalirius, swarm through France, reach up to the British Channel,

and have not crossed it, with the exception of one colony of Machaon

in the Cambridgeshire fens. I could talk long about a similar

phenomenon in the case of our migratory and singing birds; how many

exquisite species--notably those two glorious songsters, the Orphean

Warbler and Hippolais, which delight our ears everywhere on the

other side of the Channel--follow our nightingales, blackcaps, and

warblers northward every spring almost to the Straits of Dover, but

dare not cross, simply because they have been, as it were, created

since the gulf was opened, and have never learnt from their parents

how to fly over it.

In the case of fishes, again, I might say much on the curious fact

that the Cyprinidae, or white fish--carp, etc.--and their natural

enemy, the pike, are indigenous, I believe, only to the rivers,

English or continental, on the eastern side of the Straits of Dover;

while the rivers on the western side were originally tenanted, like

our Hampshire streams, as now, almost entirely by trout, their only

Cyprinoid being the minnow--if it, too, be not an interloper; and I

might ask you to consider the bearing of this curious fact on the

former junction of England and France.

But I have only time to point out to you a few curious facts with

regard to reptiles, which should be specially interesting to a

Hampshire bio-geologist. You know, of course, that in Ireland there

are no reptiles, save the little common lizard, Lacerta agilis, and

a few frogs on the mountain-tops--how they got there I cannot

conceive. And you will, of course, guess, and rightly, that the

reason of the absence of reptiles is: that Ireland was parted off

from England before the creatures, which certainly spread from

southern and warmer climates, had time to get there. You know, of

course, that we have a few reptiles in England. But you may not be

aware that, as soon as you cross the Channel, you find many more

species of reptiles than here, as well as those which you find here.

The magnificent green lizard which rattles about like a rabbit in a

French forest, is never found here; simply because it had not worked

northward till after the Channel was formed. But there are three

reptiles peculiar to this part of England which should be most

interesting to a Hampshire zoologist. The one is the sand lizard

(L. stirpium), found on Bourne-heath, and, I suspect, in the South

Hampshire moors likewise--a North European and French species.

Another, the Coronella laevis, a harmless French and Austrian snake,

which has been found about me, in North Hants and South Berks, now

about fifteen or twenty times. I have had three specimens from my

own parish. I believe it not to be uncommon; and most probably to

be found, by those who will look, both in the New Forest and

Woolmer. The third is the Natterjack, or running toad (Bufo

Rubeta), a most beautifully-spotted animal, with a yellow stripe

down his back, which is common with us at Eversley, and common also

in many moorlands of Hants and Surrey; and, according to Fleming, on

heaths near London, and as far north-east as Lincolnshire; in which

case it will belong to the Germanic fauna. Now, here again we have

cases of animals which have just been able to get hither before the

severance of England and France; and which, not being reinforced

from the rear, have been forced to stop, in small and probably

decreasing colonies, on the spots nearest the coast which were fit

for them.

I trust that I have not kept you too long over these details. What

I wish to impress upon you is that Hampshire is a country specially

fitted for the study of important bio-geological questions.

To work them out, you must trace the geology of Hampshire, and

indeed, of East Dorset. You must try to form a conception of how

the land was shaped in miocene times, before that tremendous

upheaval which reared the chalk cliffs at Freshwater upright,

lifting the tertiary beds upon their northern slopes. You must ask-

-Was there not land to the south of the Isle of Wight in those ages,

and for ages after; and what was its extent and shape? You must

ask--When was the gap between the Isle of Wight and the Isle of

Purbeck sawn through, leaving the Needles as remnants on one side,

and Old Harry on the opposite? And was it sawn asunder merely by

the age-long gnawing of the waves? You must ask--Where did the

great river which ran from the west, where Poole Harbour is now, and

probably through what is now the Solent, depositing brackish water-

beds right and left--where, I say, did it run into the sea? Where

the Straits of Dover are now? Or, if not there, where? What, too,

is become of the land to the Westward, composed of ancient

metamorphic rocks, out of which it ran, and deposited on what are

now the Haggerstone Moors of Poole, vast beds of grit? What was the

climate on its banks when it washed down the delicate leaves of

broad-leaved trees, akin to our modern English ones, which are found

in the fine mud-sand strata of Bournemouth? When, finally, did it

dwindle down to the brook which now runs through Wareham town? Was

its bed, sea or dry land, or under an ice sheet, during the long

ages of the glacial epoch? And if you say--Who is sufficient for

these things?--Who can answer these questions? I answer--Who but

you, or your pupils after you, if you will but try?

And if any shall reply--And what use if I do try? What use, if I do

try? What use if I succeed in answering every question which you

have propounded to-night? Shall I be the happier for it? Shall I

be the wiser?

My friends, whether you will be the happier for it, or for any

knowledge of physical science, or for any other knowledge

whatsoever, I cannot tell: that lies in the decision of a Higher

Power than I; and, indeed, to speak honestly, I do not think that

bio-geology or any other branch of physical science is likely, at

first at least, to make you happy. Neither is the study of your

fellow-men. Neither is religion itself. We were not sent into the

world to be happy, but to be right; at least, poor creatures that we

are, as right as we can be; and we must be content with being right,

and not happy. For I fear, or rather I hope, that most of us are

not capable of carrying out Talleyrand's recipe for perfect

happiness on earth--namely, a hard heart and a good digestion.

Therefore, as our hearts are, happily, not always hard, and our

digestions, unhappily, not always good, we will be content to be

made wise by physical science, even though we be not made happy.

And we shall be made truly wise if we be made content; content, too,

not only with what we can understand, but, content with what we do

not understand--the habit of mind which theologians call--and

rightly--faith in God; the true and solid faith, which comes often

out of sadness, and out of doubt, such as bio-geology may well stir

in us at first sight. For our first feeling will be--I know mine

was when I began to look into these matters--one somewhat of dread

and of horror.

Here were all these creatures, animal and vegetable, competing

against each other. And their competition was so earnest and

complete, that it did not mean--as it does among honest shopkeepers

in a civilised country--I will make a little more money than you;

but--I will crush you, enslave you, exterminate you, eat you up.

"Woe to the weak," seems to be Nature's watchword. The Psalmist

says: "The righteous shall inherit the land." If you go to a

tropical forest, or, indeed, if you observe carefully a square acre

of any English land, cultivated or uncultivated, you will find that

Nature's text at first sight looks a very different one. She seems

to say: Not the righteous, but the strong, shall inherit the land.

Plant, insect, bird, what not--Find a weaker plant, insect, bird,

than yourself, and kill it, and take possession of its little

vineyard, and no Naboth's curse shall follow you: but you shall

inherit, and thrive therein, you, and your children after you, if

they will be only as strong and as cruel as you are. That is

Nature's law: and is it not at first sight a fearful law?

Internecine competition, ruthless selfishness, so internecine and so

ruthless that, as I have wandered in tropic forests, where this

temper is shown more quickly and fiercely, though not in the least

more evilly, than in our slow and cold temperate one, I have said:

Really these trees and plants are as wicked as so many human beings.

Throughout the great republic of the organic world the motto of the

majority is, and always has been as far back as we can see, what it

is, and always has been, with the majority of human beings:

"Everyone for himself, and the devil take the hindmost."

Overreaching tyranny; the temper which fawns, and clings, and plays

the parasite as long as it is down, and when it has risen, fattens

on its patron's blood and life--these, and the other works of the

flesh, are the works of average plants and animals, as far as they

can practise them. At least, so says at first sight the science of

bio-geology; till the naturalist, if he be also human and humane, is

glad to escape from the confusion and darkness of the universal

battle-field of selfishness into the order and light of Christmas-

tide.

For then there comes to him the thought--And are these all the

facts? And is this all which the facts mean? That mutual

competition is one law of Nature, we see too plainly. But is there

not, besides that law, a law of mutual help? True it is, as the

wise man has said, that the very hyssop on the wall grows there

because all the forces of the universe could not prevent its

growing. All honour to the hyssop. A brave plant, it has fought a

brave fight, and has its just deserts--as everything in Nature has--

and so has won. But did all the powers of the universe combine to

prevent it growing? Is not that a one-sided statement of facts?

Did not all the powers of the universe also combine to make it grow,

if only it had valour and worth wherewith to grow? Did not the

rains feed it, the very mortar in the wall give lime to its roots?

Were not electricity, gravitation, and I know not what of chemical

and mechanical forces, busy about the little plant, and every cell

of it, kindly and patiently ready to help it if it would only help

itself? Surely this is true; true of every organic thing, animal

and vegetable, and mineral too, for aught I know: and so we must

soften our sadness at the sight of the universal mutual war by the

sight of an equally universal mutual help.

But more. It is true--too true if you will--that all things live on

each other. But is it not, therefore, equally true that all things

live for each other?--that self-sacrifice, and not selfishness, is

at the bottom the law of Nature, as it is the law of Grace; and the

law of bio-geology, as it is the law of all religion and virtue

worthy of the name? Is it not true that everything has to help

something else to live, whether it knows it or not?--that not a

plant or an animal can turn again to its dust without giving food

and existence to other plants, other animals?--that the very tiger,

seemingly the most useless tyrant of all tyrants, is still of use,

when, after sending out of the world suddenly, and all but

painlessly, many an animal which would without him have starved in

misery through a diseased old age, he himself dies, and, in dying,

gives, by his own carcase, the means of life and of enjoyment to a

thousandfold more living creatures than ever his paws destroyed?

And so, the longer one watches the great struggle for existence, the

more charitable, the more hopeful, one becomes; as one sees that,

consciously or unconsciously, the law of Nature is, after all self-

sacrifice: unconscious in plants and animals, as far as we know;

save always those magnificent instances of true self-sacrifice shown

by the social insects, by ants, bees, and others, which put to shame

by a civilisation truly noble--why should I not say divine, for God

ordained it?--the selfishness and barbarism of man. But be that as

it may, in man the law of self-sacrifice--whether unconscious or not

in the animals--rises into consciousness just as far as he is a man;

and the crowning lesson of bio-geology may be, when we have worked

it out after all, the lesson of Christmas-tide--of the infinite

self-sacrifice of God for man; and Nature as well as religion may

say to us:

Ah, could you crush that ever craving lust

For bliss, which kills all bliss, and lose your life,

Your barren unit life, to find again

A thousand times in those for whom you die--

So were you men and women, and should hold

Your rightful rank in God's great universe,

Wherein, in heaven or earth, by will or nature,

Naught lives for self. All, all, from crown to base--

The Lamb, before the world's foundation slain--

The angels, ministers to God's elect--

The sun, who only shines to light the worlds--

The clouds, whose glory is to die in showers--

The fleeting streams, who in their ocean graves

Flee the decay of stagnant self-content--

The oak, ennobled by the shipwright's axe--

The soil, which yields its marrow to the flower--

The flower, which feeds a thousand velvet worms

Born only to be prey to every bird--

All spend themselves on others: and shall man,

Whose twofold being is the mystic knot

Which couples earth with heaven, doubly bound,

As being both, worm and angel, to that service

By which both worms and angels hold their life,

Shall he, whose every breath is debt on debt,

Refuse, forsooth, to be what God has made him?

No; let him show himself the creatures' Lord

By free-will gift of that self-sacrifice

Which they, perforce, by Nature's law's endure.

My friends, scientific and others, if the study of bio-geology shall

help to teach you this, or anything like this, I think that though

it may not make you more happy, it may yet make you more wise; and,

therefore, what is better than being more happy, namely, more

blessed.
