Dividend Two Directory 19It is interesting to note, too, that anticipations of higher types, so to speak, often occur among lower races. An animal here and there among the simpler forms hits upon some device essentially similar to that of some higher group with which it is really quite unrelated. For example, those who have read my account of the common earwig (given in the sixth chapter of "Flashlights on Nature") will recollect how that lowly insect sits on her eggs much as a hen does, and brings up her brood of callow grubs as if they were chickens. In much the same way, anticipations of the mammalian type occur pretty frequently among lower animals. Our commonest English lizard, for example, which frequents moors and sandhills, does not lay or deposit its eggs at all, but hatches them out in its own body, and so apparently brings them forth alive: while among snakes, the same habit occurs in the adder or viper. The very name _viper_, indeed, is a corruption of _vivipara_, the snake which produces living young. Still more closely do some birds resemble mammals in the habit of secreting a sort of milk for the sustenance of their nestlings. Most people think the phrase "pigeon's milk" is much like the phrase "the horse-marines," a burlesque name for an absurd and impossible monstrosity. But it is nothing of the sort: it answers to a real fact in the economy of certain doves, which eat grain or seeds, grind and digest it in their own gizzards into a fine soft pulp or porridge, and then feed their young with it from their crops and beaks. This is thus a sort of bird-like imitation of milk. Only the cow or the goat takes grass or leaves, chews, swallows, and digests them, and manufactures from them in her own body that much more nutritive substance, milk, with which all mammals feed their infant offspring. We went down all the time on troubled waters, with rocky banks and innumerable obstacles all the way. We went through another terrible and most intricate rapid--the Labyrinth--and passed through a channel only 40 m. wide between high rocky banks. Then, after that, for 9,500 m. we had fair and smooth navigation, with a range of flat-topped hills 300 ft. high, extending from W.S.W. to E.N.E., in front of us to the north-west. Here there was a regular maze of channels, all more or less bad. We did not follow the principal one, which was strewn with rocks, but a smaller one, at the end of which, unfortunately, we found a barrier of rocks which we could not surmount. We had all the trouble of dragging the canoe back up the rapid until we could turn her round into another channel. | |
