"What's that?" demanded Andy Sudds.

Washington White dropped the plate he was carrying to the table and ran to the door. Before he could open it, the door was broken in by the Indians, who came pouring in, loudly jabbering in their native tongue.

"A 'quake, sure enough!" ejaculated Phineas Roebach, getting quickly on his feet.

As he spoke, there was a repetition of the shock, only greatly increased. The oil hunter was thrown to the floor, as was everybody else in the house who was not seated. The roof of the cabin creaked and threatened to descend upon their heads.

The Indians, uttering cries of alarm, scrambled out of the cabin faster than they came in. But they had nothing on Washington White there. He was the first person to get through the door.

The white people followed the others in quick time. Jack and Mark felt that if the cabin was going to fall, the open air was the safer place. Here, however, it seemed that they could not keep their feet. They reeled about like drunken men, and the forest trees bent and writhed as though an invisible wind tore at them, whereas the fact was that the wind had fallen and it was a dead calm.

The air about them seemed to rock with the shock, there was a dull roaring sound which hummed continually in their ears, and the vibrations of the earth continued. They were indeed experiencing a most serious earthquake.

CHAPTER X

THE BLACK DAY

The 'quake was over in a very few moments; the Indians and Washington
White, however, cowered upon the ground for some time, crying out their
fear of what they considered supernatural phenomena. Jack Darrow and
Mark Sampson were not frightened in the same way as the darkey and the
Aleuts; nevertheless they were much shaken.
