One door of the passage was open, and in spite of the thick furs in which they were wrapped, all felt chilled to the very marrow of their bones; and when the second door was pushed open, they recoiled for an instant, panting for breath, whilst the moisture held in suspension in the air of the passage covered the walls and the floor with fine snow.
The weather outside was extremely dry, and the stars shone with extraordinary brilliancy. Sergeant Long rushed out without a moment's hesitation, dragging the cord behind him, one end of which was held by his companions; the outer door was pushed to, and Hobson, Mae-Nab, and Rae went back to the passage and closed the second door, behind which they waited. If Long did not return in a few minutes, they might conclude that his enterprise had succeeded, and that, safe in the shed, he was loading the first train with fuel. Ten minutes at the most ought to suffice for this operation, if he had been able to get the door open.
When the Sergeant was fairly off, Hobson and Mac-Nab walked together towards the end of the passage.
Meanwhile Rae had been watching the bears and the loft. It was so dark that all hoped Long's movements would escape the notice of the hungry animals.
Ten minutes elapsed, and the three watchers went back to the narrow space between the two doors, waiting for the signal to be given to drag in the sledge.
Five minutes more. The cord remained motionless in their hands! Their anxiety can be imagined. It was a quarter of an hour since the Sergeant had started, plenty of time for all he had to do, and he had given no signal.
Hobson waited a few minutes longer, and then tightening his hold of the end of the rope, he made a sign to his companions to pull with him. If the load of wood were not quite ready, the Sergeant could easily stop it from being dragged away.
The rope was pulled vigorously. A heavy object seemed to slide along the snow. In a few moments it reached the outer door.
It was the body of the Sergeant, with the rope round his waist. Poor Long had never reached the shed. He had fallen fainting to the ground, and after twenty minutes' exposure to such a temperature there was little hope that he would revive.
A cry of grief and despair burst from the lips of Mac-Nab and Rae. They lifted their unhappy comrade from the ground, and carried him into the passage; but as the Lieutenant was closing the outer door, something pushed violently against it, and a horrible growl was heard.
