something like distant thunder, and something like the noise of a great tree crashing to the earth after it has been cut, and something like the sound that comes before an earthquake.

It is not strange that Chick did not know that sound. No one ever hears anything just like it, unless he is out where the snow is very light and very deep and covered with a crust.

Then, if the crust is broken suddenly in one place, it may settle like the top of a puffed-up pie that is pricked; and the air that has been prisoned under the crust is pushed out with a strange and mighty sound.

So that big Booooooom meant that something had broken the icy crust which, a moment before, had lain over the soft snow, all whole, for a mile one way and a mile another way, and half a mile to the Farm-House.

Yes, there was the Farmer Boy coming across the field, to the orchard that stood on the sandy hillside near the fir forest. He was walking on snowshoes, which cracked the crust now and then; and twice on the way to the orchard he heard a deep Booooooom, which he loved just as much as he loved the silence of the field when he stopped to listen now and then. For the winter sounds were so dear to the Farmer Boy who lived at the edge of Christmas-tree Land, that he would never forget them even when he should become a man. He would always remember the snowshoe tramps across the meadow; and in after years, when his shoulders held burdens he could not see, he would remember the bulky load he carried that morning without minding the weight a bit; for it was a big bag full of Christmas gifts, and the more heavily it pressed against his shoulder, the lighter his heart felt.

When he reached the orchard, he dropped the bag on the snow and opened it. Part of the gifts he spilled in a heap near the foot of a tree, and the rest he tied here and there to the branches. Then he stood still and whistled a clear sweet note that sounded like "Fee-bee."

Now, Chick, over by the willows had not known what Booooooom meant, for that was not in his language. But he understood "Fee-bee" in a minute, although it was not nearly so loud. For those were words he often used himself. They meant, perhaps, many things; but always something pleasant. "Fee-bee" was a call he recognized as surely as one boy recognizes the signal whistle of his chum.

So, of course, Chick flew to the orchard as quickly as he could and found his present tied fast to a branch. The smell of it, the feel of it, the taste of it, set him wild with joy. He picked at it with his head up, and sang "Chick, D.D." He picked at it with his head down and called, "Chick, D.D.D.D.D.D.D., Chick, D.D." He flew here and there, too gay with happiness to stay long anywhere, and found presents tied to other branches, too. At each one he sang "Chick, D.D., Chick, D.D.D. Dee Deee Deeee." It was, "indeed" the song of a hungry bird who had found good rich suet to nibble.

The Farmer Boy smiled when he heard it, and waited, for he thought others would hear it, too. And they did. Two birds with black-feather cap and bib heard it and came; and before they had had time to go frantic with delight and song, three others just like them came, and then eight more, and by that time there was such a "Chick"-ing and "D.D."-ing and such a whisking to and fro of black caps and black bibs, that no one paid much attention when Minister Chick, D.D., himself, perched on a branch for a minute, and gave the sweetest little warble that was ever heard on a winter's day. Then he whistled "Fee-bee" very clearly, and went to eating again, heeding the Farmer Boy no more than if he were not there at all.

And he wasn't there very long; for he was hungry, too; and that made him think about the good whiff he had smelled when he went through the kitchen with the snowshoes under his arm, just before he strapped them over his moccasins outside the door.

Yes, that was the Farmer Boy going away with a clatter over the snow-crust; but who were these coming through the air, with jerky flight, and with a jerky note something like "Twitterty-twit-twitterty-twit-twitterty-twitterty-twitterty-twit"? They flew like goldfinches, and they sounded like goldfinches, both in the twitterty song of their flight and their "Tweeet" as they called one another. But they were not goldfinches. Oh, my, no! For they were dressed in gray, with darker gray stripes at their sides; and when they scrambled twittering down low enough to show their heads in the sunlight, they could be seen to be wearing the loveliest of crimson caps, and some of them had rosy breasts.

The redpolls had come! And they found on top of the snow a pile of dusty sweepings from the hay-mow, with grass-seeds in it and some cracked corn and crumbs. And there were squash-seeds, and sunflower-seeds, and seedy apple-cores that had been broken up in the grinder used to crunch bones for the chickens; and there were prune-pits that had been cracked with a hammer.

The joy-songs of the birds over the suet and seeds seemed a signal through the countryside; and before long others came, too.

Among them there was a black-and-white one, with a patch of scarlet on the back of his head, who called, "Ping," as if he were speaking through his nose. There was one with slender bill and bobbed-off tail, black cap and white breast, grunting, "Yank yank," softly, as he ate.

But there was none to come who was braver or happier than Chick, D.D., and none who sang so gayly. After that good Christmas feast he and his flock returned each day; and when, in due time, the ice melted from the branches, it wasn't just suet they ate. It was other things, too.

That is how it happened that when, early in the spring, the Farmer Boy examined the apple-twigs, to see whether he should put on a nicotine spray for the aphids and an arsenical spray for the tent caterpillars, he couldn't find enough aphids to spray or enough caterpillars, either. Chick, D.D. and his flock had eaten their eggs.

Again, late in the summer, when it was time for the yellow-necked caterpillars, the red-humped caterpillars, the tiger caterpillars, and the rest of the hungry crew, to strip the leaves from the orchard, the Farmer Boy walked among the rows, to see how much poison he would need to buy for the August spray. And again he found that he needn't buy a single pound. Chick, D.D. and his family were tending his orchard!

Yes, Minister Chick was a servant in the good world he lived in. He saved leaves for the trees, he saved rosy apples for city girls and boys to eat, and he saved many dollars in time and spray-money for the Farmer Boy.

And all he charged was a living wage: enough suet in winter to tide him over the icy spells, and free house-rent in the old hollow post the Farmer Boy had nailed to the trunk of one of the apple trees.

That old hollow post was a wonderful home. Chick, D.D. had crept into it for the first time Christmas afternoon, when he had eaten until dusk overtook him before he had time to fly back to the shelter of the fir forest. He found that he liked that post. Its walls were thick and they kept out the wind; and, besides, was it not handy by the suet?

In the spring he liked it for another reason, too—the best reason in the world. It gave great happiness to Mrs. Chick. "Fee-bee?" he had asked her as he called her attention to it; and "Fee-bee," she had replied on looking it over. So he said, "Chick, D.D." in delight, and then perched near by, while he warbled cosily a brief song jumbled full of joy.

Chick and his mate had indeed chosen well, for it is a poor wall that will not work both ways. If the sides of the hollow post had been thick enough to keep
