One Charles Durand, of whose travels and adventures a book has been written, owned a cockatoo, which he carried about with him on his journeys; the bird's name was Billy, and he seems to have been as wise as he was loving. Charles was asleep in his tent, when he was roused by a sharp, shrill cry of the bird, of "Time to rise! time to rise!" accompanied by a violent flapping of the wings. So awakened, Charles looked around, wondering what had disturbed his feathered friend. The cause was soon plain--a deadly snake lay coiled up close to his bed, prepared to spring on the defenseless man. Just when he thought that all hope was at an end, the brave cockatoo sprang from his perch, seized the reptile by the neck, and held him tight till his master could summon help.
Higher up in the scale of life we get many instances which show various stages in the same progressive development towards greater care for the safety and education of the young. Among the larger lizards, for example, a distinct advance may be traced between the comparatively uncivilized American alligator and his near ally, the much more cultivated African crocodile. On the banks of the Mississippi, the alligator lays a hundred eggs or thereabouts, which she deposits in a nest near the water's edge, and then covers them up with leaves and other decaying vegetable matter. The fermentation of these leaves produces heat and so does for the alligator's eggs what sitting does for those of hens and other birds: the mother deputes her maternal functions, so to speak, to a festering heap of decomposing plant-refuse. Nevertheless, she loiters about all the time, like Miriam round the ark which contained Moses, to see what happens; and when the eggs hatch out, she leads her little ones down to the river, and there makes alligators of them. This is a simple and relatively low stage in the nursery arrangements of the big lizards.
