"I'm afraid—we can't—catch them, Muky," panted the younger. "What do you think—"
He stopped, for Mukoki had thrown himself on his knees in the snow a dozen feet in front of the teams. From that point there ran straight ahead of them the trail of the dog mail. For perhaps a full minute he examined the imprints of the dogs' feet and the smooth path made by the sledge. Then he looked up, and with one of those inimitable chuckles which meant so much when coming from him, he said:
"We catch heem—sure! See—sledge heem go deep. Both ride. Big load for dogs. We catch heem—sure!"
"But our dogs!" persisted Wabigoon, his face still filled with doubt. "They're completely bushed, and my leader has gone lame. See how they're bleeding!"
The huskies, as the big wolfish sledge-dogs of the far North are called, were indeed in a pitiable condition. The warm sun had weakened the hard crust of the snow until at every leap the feet of the animals had broken through, tearing and wounding themselves on its ragged, knife-like edges. Mukoki's face became more serious as he carefully examined the teams.
"Bad—ver' bad," he grunted. "We fool—fool!"
"For not bringing dog shoes?" said Wabigoon. "I've got a dozen shoes on my sledge—enough for three dogs. By George—" He leaped quickly to his toboggan, caught up the dog moccasins, and turned again to the old Indian, alive with new excitement. "We've got just one chance, Muky!" he half shouted.
"Pick out the strongest dogs. One of us must go on alone!"
The sharp commands of the two adventurers and the cracking of Mukoki's whip brought the tired and bleeding animals to their feet. Over the pads of three of the largest and strongest were drawn the buckskin moccasins, and to these three, hitched to Wabigoon's sledge, were added six others that appeared to have a little endurance still left in them. A few moments later the long line of dogs was speeding swiftly over the trail of the Hudson Bay mail, and beside the sled ran Wabigoon.
Thus this thrilling pursuit of the dog mail had continued since early dawn. For never more than a minute or two at a time had there been a rest. Over mountain and lake, through dense forest and across barren plain man and dog had sped without food or drink, snatching up mouthfuls of snow here and there—always their eyes upon the fresh trail of the flying mail. Even the fierce huskies seemed to understand that the chase had become a matter of life and death, and that they were to follow the trail ahead of them, ceaselessly and without deviation, until the end of their masters was accomplished. The human scent was becoming stronger and stronger in their wolf-like nostrils. Somewhere on that trail there were men, and other dogs, and they were to overtake them!
