I dare say you notice that all the birds in this picture have long beaks. We may be sure from this that they live in places and seek for their food in ways in which long beaks are just what they want. The fact is they are all marsh birds, and the soil of marshes being wet and soft, and full of worms, these long beaks enable them to probe it, and so get at the worms. I think the beaks of birds afford a striking example of how good God is in adapting creatures to the mode of life He has appointed for them. The eagles and hawks, you know, are provided with strong, short bills to enable them to seize and tear flesh. Those of canaries and all the finches are just the very instruments to crack seeds with. Parrots, with their tremendous weapons, can crush the hardest nuts of the tropic forest. The crossbill is fitted with a wonderful tool for tearing fir-cones to pieces. Robins and the other warblers have soft bills, which are all they want for eating insects and grubs.
Now, we have seen that the question of the antiquity of man is intimately connected with that of the Glacial Age. That is to say, the relics of man as far as we know them in Europe, are found under such circumstances that we feel confident they are not far removed from the period of cold. For it will be found that those conservative scholars who do not think that man preceded the Glacial Age, or inhabited Europe during the long course of years included in that period, do think he came into Europe as soon as it passed away. So, in any case, if we can determine the date of the Glacial Age, we shall have made a most important step in advance in solving the problem of the antiquity of man himself. So it seems to us best to go over the subject of the Glacial Age again, and see what conclusions some of our best thinkers have come to as to its cause, when it occurred, and other matters in relation to it.
In No. 4 we have an illustration of the tube-mouth or Solenostoma, one of the two known kinds of fish in which the female shows a sense of her position as a mother. The tube-mouth, as you can see at a glance, is a close relation of our old friend the seahorse, whose disguised and undisguised forms in Australia and the Mediterranean we have already observed when dealing with the question of animal masqueraders. Solenostoma is a native of the Indian Ocean, from Zanzibar to China. In the male, the lower pair of fins are separate, as is usual among fish; but in the female, represented in the accompanying sketch, they are lightly joined at the edge, so as to form a sort of pouch like a kangaroo's, in which the eggs are deposited after being laid, and thus carried about in the mother's safe keeping. No. 5 shows the arrangement of this pouch in detail, with the eggs inside it. The mother Solenostoma not only takes charge of the spawn while it is hatching in this receptacle, but also looks after the young fry, like the father stickleback, till they are of an age to go off on their own account in quest of adventures. The most frequent adventure that happens to them on the way is, of course, being eaten.
