In the stretch of deep sand he had to cross the weight was killing. The drag of the heavy boots seemed to pull his legs from their sockets but he did not slacken his pace. His breath was coming in gasps when he started up the steep trail which led from the sand over a high promontory. He clutched at bushes, rocks, anything to pull himself up and the pounding of his heart sounded to him like the chug of a steamboat, before he reached the top.
The veins and arteries in his forehead and neck seemed bursting, as did his over-taxed lungs, when he started stumbling and sliding down the other side. It was not the distance he had covered which had so winded him, nor even the terrific pace, but the dragging weight of the hip-boots. They felt as though they were soled with lead.
He imagined that he had crawled but as a matter of fact the distance would never be covered in the same space of time again.
The perspiration was trickling from his hair and through his thick eyebrows when he reached the boat landing where ordinarily they crossed. He brushed it out of his eyes with the back of his sleeve and stared at the place where usually the boat rode. It was gone! Smaltz had taken it instead of the overhead tram in which he always crossed.
There was no time to speculate as to Smaltz's reason. He kept on running along the river until he came to the steps of the platform where the heavy iron cage, suspended from a cable, was tied to a tree. Bruce bounded up the steps two at a time and loosened the rope. It was not until then that he saw that the chain and sprocket, which made the crossing easy, were missing. This, too, was strange. There was no time for speculation. Could he cross in it hand over hand? For answer he put his knee on the edge and kicked off.
The impetus sent it well over the river. Then it struck the slack in the cable and slowed up. Bruce set his teeth and went at it hand over hand. The test came when it started up grade. No ordinary man could have budged it and Bruce pulled to the very last ounce of his strength. He moved it only an inch at a time--slipping back two inches frequently when he changed hands.
If he lost the grip of both hands for a single second and slid back to the middle of the slack he realized that he was too near exhausted to pull up again, so, somehow, he hung on, making inarticulate sounds as he exerted superhuman strength, groaning like an animal loaded beyond its limit. If only he could last!
