Rh his mother, stretches his legs straight out behind him on the rock, and lies like this for a few seconds, as we sometimes see a cat or a dog do. Then he comes out, preens himself, and voids his excrement, and I cannot but record—for indeed it was very funny—that this hits exactly in the eye, and over the face generally, another guillemot standing about two feet from him on the edge of the ledge. The poor bird thus distinguished stands with a comical look, and for some while shakes its head very vigorously. Later, when it comes somewhat near to the chick, the latter's mother utters the jodel in a warning tone of voice, seeming to say, "Thus far, but no farther." The chick, having preened itself a little, goes again to its mother, and is received this time beneath her other wing, which is the farther one. I look down upon them now a little more perpendicularly, so that he seems almost to have disappeared altogether.

It is really wonderful—and the incident just given illustrates it—what a power all these sea-birds have of ejecting their excrement to a distance. Not only is it propelled with great force forwards, but also upwards, so that its course is crescentic; and in this, perhaps, we may look back to a time when the guillemot and fulmar petrel made nests, for it is by this arrangement that the nest of the shag is kept clean whilst the rock all about it is coated with excrement. I mention the fulmar petrel as well as the guillemot, because, whatever may be the case elsewhere, here
