"That was an awful big quake," replied Zeb, with a white face. "It almost got us that time, Dorothy."

The horse had stopped short, and stood firm as a rock. Zeb shook the reins and urged him to go, but Jim was stubborn. Then the boy cracked his whip and touched the animal's flanks with it, and after a low moan of protest Jim stepped slowly along the road.

Neither the boy nor the girl spoke again for some minutes. There was a breath of danger in the very air, and every few moments the earth would shake violently. Jim's ears were standing erect upon his head and every muscle of his big body was tense as he trotted toward home. He was not going very fast, but on his flanks specks of foam began to appear and at times he would tremble like a leaf.

The sky had grown darker again and the wind made queer sobbing sounds as it swept over the valley.

Suddenly there was a rending, tearing sound, and the earth split into another great crack just beneath the spot where the horse was standing. With a wild neigh of terror the animal fell bodily into the pit, drawing the buggy and its occupants after him.
