CLEWE'S THEORY.
Seated in the car, which was steadily ascending the great shaft, Roland Clewe took no notice of anything about him.

He did not look at the brilliantly lighted interior of the shaft, he paid no attention to his instruments, he did not consult his watch, nor glance at the dial which indicated the distance he had travelled.

Several times the telephone bell rang, and Bryce inquired how he was getting along; but these questions he answered as briefly as possible, and sat looking down at his knees and seeing nothing.
When he was half-way up, he suddenly became conscious that he was very hungry.

He hurriedly ate some sandwiches and drank some water, and then, again, he gave himself up entirely to mental labor.
