The raid which Larkins's dog made upon our camp was amusing rather than annoying. He was a very friendly and intelligent shepherd dog, probably a collie. Hardly had we sat down to our first lunch in camp before he called on us. But as he was disposed to be too friendly, and to claim too large a share of the lunch, we rather gave him the cold shoulder. He did not come again; but a few evenings afterward, as we sauntered over to the house on some trifling errand, the dog suddenly conceived a bright little project. He seemed to say to himself, on seeing us, "There come both of them now, just as I have been hoping they would; now, while they are away, I will run quickly over and know what they have got that a dog can eat." My companion saw the dog get up on our arrival, and go quickly in the direction of our camp, and he said something in the cur's manner suggested to him the object of his hurried departure. He called my attention to the fact, and we hastened back. On cautiously nearing camp, the dog was seen amid the pails in the shallow water of the creek investigating them. He had uncovered the butter, and was about to taste it, when we shouted, and he made quick steps for home, with a very "kill-sheep" look. When we again met him at the house next day he could not look us in the face, but sneaked off, utterly crestfallen. This was a clear case of reasoning on the part of the dog, and afterward a clear case of a sense of guilt from wrong-doing. The dog will probably be a man before any other animal. III BIRDS' EGGS "Admire the bird's egg and leave it in its nest" is a wiser forbearance than "Love the wood-rose and leave it on its stalk." We will try to leave these eggs in the nest, and as far as possible show the bird and the nest with them. The first egg of spring is undoubtedly a hen's egg. The domestic fowls, not being compelled to shift for themselves, and having artificial shelter, are not so mindful of the weather and the seasons as the wild birds. But the hen of the woods and the hen of the prairie, namely, the ruffed and the pinnated grouse, do not usually nest till the season is so far advanced that danger from frost is past. The first wild egg, in New York and New England, is probably that of an owl, the great horned owl, it is said, laying as early as March. They probably shelter their eggs from the frost and the snow before incubation begins. The little screech owl waits till April, and seeks the deep snug cavity of an old tree; the heart of a decayed apple-tree suits him well. Begin your search by the middle of April, and before the month is past you will find the four white, round eggs resting upon a little dry grass or a few dry leaves in the bottom of a long cavity. Owls' eggs are inclined to be spherical. You would expect to see a big, round-headed, round-eyed creature come out of such an egg.
