It was Mourner the Dove whom Peter saw, an old friend of whom Peter is very fond. His body was a little bigger than that of Welcome Robin, but his long slender neck, and longer tail and wings made him appear considerably larger. In shape he reminded Peter at once of the Pigeons up at Farmer Brown's. His back was grayish-brown, varying to bluish-gray. The crown and upper parts of his head were bluish-gray. His breast was reddish-buff, shading down into a soft buff. His bill was black and his feet red. The two middle feathers of his tail were longest and of the color of his back. The other feathers were slaty-gray with little black bands and tipped with white. On his wings were a few scattered black spots. Just under each ear was a black spot. But it was the sides of his slender neck which were the most beautiful part of Mourner. When untouched by the Jolly Little Sunbeams the neck feathers appeared to be in color very like his breast, but the moment they were touched by the Jolly Little Sunbeams they seemed to be constantly changing, which, as you know, is called iridescence. Altogether Mourner was lovely in a quiet way. But it was not his appearance which made Peter stare; it was what he was doing. He was walking about and every now and then picking up something quite as if he were getting his breakfast in that gravel pit, and Peter couldn't imagine anything good to eat down there. He knew that there were not even worms there. Besides, Mourner is not fond of worms; he lives almost altogether on seeds and grains of many kinds. So Peter was puzzled. But as you know he isn't the kind to puzzle long over anything when he can use his tongue. “Hello, Mourner!” he cried. “What under the sun are you doing in there? Are you getting your breakfast?” “Hardly, Peter; hardly,” cooed Mourner in the softest of voices. “I've had my breakfast and now I'm picking up a little gravel for my digestion.” He picked up a tiny pebble and swallowed it. “Well, of all things!” cried Peter. “You must be crazy. The idea of thinking that gravel is going to help your digestion. I should say the chances are that it will work just the other way.” Mourner laughed. It was the softest of little cooing laughs, very pleasant to hear. “I see that as usual you are judging others by yourself,” said he. “You ought to know by this time that you can do nothing more foolish. I haven't the least doubt that a breakfast of gravel would give you the worst kind of a stomach-ache. But you are you and I am I, and there is all the difference in the world. You know I eat grain and hard seeds. Not having any teeth I have to swallow them whole. One part of my stomach is called a gizzard and its duty is to grind and crush my food so that it may be digested. Tiny pebbles and gravel help grind the food and so aid digestion. I think I've got enough now for this morning, and it is time for a dust bath. There is a dusty spot over in the lane where I take a dust bath every day.”
