David's mother had the maid throw out crusts of bread and tie lumps of fat on the trees all winter, because when the snow is on the ground it is sometimes hard for the birds to find things enough to eat.
There was a plenty of things for the birds to eat now, and they were easy enough to get, but some birds were picking at the scraps.
Suddenly the birds flew up into a tree and two gray squirrels came and gnawed at the bread crusts, when the two crows that had chased David's cat came flapping down and tried to get at the scraps.
But the squirrels stopped eating and chased the crows savagely; and the crows didn't fight back, but they just flew up a little bit of a way and hovered there until the squirrels began to eat again.
Then they flapped down on the ground and began to sneak up toward the scraps; and the squirrels darted at them and chased them again.
THE SQUIRRELS CHASED THE CROWS
David wasn't very near, and he had watched the squirrels and the crows for some time.
