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 Cyprinidæ, 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 lævis, 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
