When baboons go on marauding expeditions, they show that they realise perfectly what they are doing by moving with great stealth. Not a sound is uttered. If any thoughtless youngster so far forgets the necessities of the occasion as to utter a single chatter, he is given a reminder in the shape of a box on the ear. ‘A certain Mr. Cops, who had a young orang, gave it half an orange one day, and put the other half away out of its sight on a high press, and lay down himself on the sofa. But the ape’s movements, attracting his attention, he only pretended to go to sleep. The creature came cautiously and satisfied himself that his master was asleep, then climbed up the press, ate the rest of the orange, carefully hid the peel among the shavings in the grate, examined the pretended sleeper again, and then went and lay down on his own bed.’ This incident is recorded by Tylor in his ‘Anthropology.’ ‘And such behaviour,’ he adds, ‘is to be explained only by supposing a train of thought to pass through the brain of the ape somewhat similar to what we ourselves call reason.’ These instances of undoubted intelligence and thought might be added to almost without number if there was room. Every person nearly who has been in the world any length of time, and has had occasion to associate with these so-called ‘machines,’ has seen for himself, often unexpectedly, many flashes of brightness among them. It has been said that man differs from other animals, and is superior to them in the fact that he modifies his environment while other animals do not, but are modified by environment. Mr. Lester F. Ward makes this distinction in his ‘Pure Sociology.’ The distinction is no nearer the truth than other distinctions of like character that have from time to time been drawn between men and other animals. It is not much more than half true, if it is that, and does not by any means deserve the italics awarded to it by this writer. Many races of non-human beings have a far greater influence on their environment than many races of men have. Many tribes of men wander about naked, build no habitations, make no weapons, and feed upon the fruits, roots, insects, and such other chance morsels as they can pick up from day to day in their wanderings. Such races are far inferior in constructive activity to the birds, who build elaborate houses, and to the beavers, who not only construct substantial dwellings, but dam rivers, and cut down trees and transport them long distances, and dig artificial waterways, to be used as aids in their engineering enterprises. Compare the elaborate compartments of the Australian bower-birds, surrounded with ornamented and carefully-kept grounds, with the lean-to of many savage tribes, made by sticking two or three palm-leaves in the ground and leaning them against a pole. Even ants plant crops, make clearings, build roads and tunnels, etc. It must be remembered, too, that, however affirmative and masterful a race of men may become, it
