Elliot hesitated for the better part of a day, then came to an impulsive decision. He knew the evil fame of Fifty-Mile Swamp--that no trail in Alaska was held to be more difficult or dangerous. He knew too what a fearful pest the mosquitoes were. Peter had told him a story of how he and a party of engineers had come upon a man wandering in the hills, driven mad by mosquitoes. The traveler had lost his matches and had been unable to light smudge fires. Day and night the little singing devils had swarmed about him. He could not sleep. He could not rest. Every moment for forty-eight hours he had fought for his life against them. Within an hour of the time they found him the man had died a raving maniac.
