The others went away and he began to build his winter house beside the biggest ditch. He placed it among some bushes, so that if the water in the ditch should ever overflow they would help hold his house in place. He built it with his mouth, bringing great mouthfuls of grass roots and rushes and dropping them on the middle of the heap. Sometimes they stayed there and sometimes they rolled down. If they rolled down he never brought them back, for he knew that they would be useful where they were. When it was done, the house was shaped like a pine cone with the stem end down, for after he had made it as high as a tall milkweed he finished off the long slope up which he had been running and made it look like the other sides.
