A hasty examination confirmed his statement. There was a vigorous stream of water running directly under the bunks, and worse still, as an exploration with torches soon revealed, the water was not only running in under the lower logs of the hut, but was also pouring through every opening it could find in the chinking of the walls above, and streaming into the bunks.
The Doctor hastily went outside to study conditions and, returning, said:
"There's a terrific rain on, boys, and the thermometer stands at fifty. So the snow is melting rapidly, and the two things together—the rain and the melting snowdrift—are flooding us."
Tired and sleepy as Jack was, he rose instantly to the occasion.
"There's no sleep for us to-night, boys!" he said. "We must go to work at once and dig the house out of the snowdrift. Get some fatwood torches ready and let's go to work."
The boys responded quickly, and presently all of them except Ed, whom the Doctor forbade to do any further work that involved strenuous physical exertion, were engaged in shoveling the snow away from the house and opening a passageway around it fully eight feet wide.
By daylight this was accomplished. It put an end to the inflow of water through the chinking of the upper logs; but, as Tom expressed it, there was still "a young river" flowing into the house, from the bottom of the snow bank, underneath the lower logs of the hut. Not only was all the warm rain flowing through the snow bank, but in its passage it was dissolving a great deal of the snow, and so the volume of water flowing out at the bottom and running into the house was quite double that which the rain itself would have supplied.
"We ought to have made a bank of earth around the lower part of the cabin," said the Doctor, after studying the situation for a time.
"True," said Jack, "but we had no tools with which to do it. Neither have we any now. So I don't see what is to be done."
"I do!" said Tom, the alert of mind. "I do, and it is perfectly simple."
