ose 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
