We went to work with the spade, pretending not to notice the little runaway, who hopped close to us and screamed at his little innocent mate in the cage. We threw some worms in at the open door for the bird on the inside, who ate them, taking no notice of her companion on the outside.

Suddenly the outsider hopped to the hole where we were digging and tried to grab the worms before we had time to pick them up. But we cheated him, understanding his little game, and dodged past him with the coveted worms. He, standing on tiptoe, danced about in the funniest fashion, still trying to snatch the worms. All at once, taunting him with a good long-worm, we threw it past him into the cage. Away the bird ran after it, and the little fellow who loved so well to "play hookie" was caught once more.

[CHAPTER XXII.]

MORE ABOUT OUR ROBIN.

When the robins were two years old, we noticed that they were picking up straws from the bottom of the cage, and so we "took the hint." We looked all about to find something that was the shape of a nest. We were tempted at first to put a little open-work basket in the cage, but we remembered an experience which we had some years before, and did not use the basket.

The experience was this. We hung a tiny basket in the canary's cage, and the birds made a thin nest in it and hatched their eggs. The male had been very active, helping his mate in all the ways he could think of, and he thought he would mend the nest one day. So he began to peck at the string through the meshes of the basket, reaching up from the bottom. We did not think he was doing any harm, till we noticed what looked like a bird's foot hanging down through the bottom of the basket. What was our astonishment to find that the old bird had pulled off the legs of the young birds, stupidly thinking that he was tugging at the twine.

Of course we did not put a basket in the robins' cage, but we found a round butter mould, which answered just as well. The birds were very much pleased with the butter mould, and began carrying straw and mud which we gave to them, until they had quite a respectable robin's nest. We do not know whether wild robins would nest in a butter mould, if we should fasten it in the crotch of an apple tree or swing it from the branches, but it would be quite worth one's while to try, if one is living where there are wild robins.

One morning we found a blue egg in the nest. The birds were surprised. They hopped on the rim of the butter mould and looked at the egg and chirped at it, and then the male bird hopped in and sat down on it. We clapped our hands and called to the whole family to "come and see."

But what do you think that naughty bird did? Just as we were all feeling sure of his good sense, he jumped suddenly out of the nest and then back again. Then he began to scratch with both feet as fast as he could, till the egg went out of the nest and lay in fragments on the bottom of the cage. We expected to see his mate resent it, but she took no notice, going on pecking at a peach as if nothing had happened.
