A half-breed trader, long resident at a point perhaps two hundred miles lower down the Kuskokwim, told me of coming back to a populous village after an absence of a few weeks, to find every person dead and the starving dogs tearing at the rotting corpses. It is terrible to think what the irruption of a new disease may mean to these primitive natives. Even a disease like measles, rarely fatal and not commonly regarded as serious amongst whites, takes to itself a strange and awful virulence when it invades this virgin blood. The people know no proper treatment; maddened by the itching rash that covers the body, they fling off all cover, rush outdoors naked, whatever the weather, and either roll in the snow or plunge into the stream; with the result that the disease "strikes in" and kills them. Such is the description that is given of its course along the lower Yukon and Kuskokwim. At many a Yukon village half the people died, despite the aid the few missionaries then on the river could afford; upon the Kuskokwim the havoc seems to have been still greater. Six years later, death again stalked through this region after having visited the Yukon, and this time seized his victims by the throat. In another chapter has been given some account of an outbreak of diphtheria on the Chandalar, following a more serious epidemic at Circle City and Fort Yukon. It was during that same winter the disease raged in this region, remote from any sort of medical or even intelligent lay aid, and swept off all the children that had been spared by the measles or had been born since that time. At our next stopping-place we saw the graves of nineteen children who died in one day! [Sidenote: THE INDIAN GUIDE] We learned that we were now within one day's travel of a road-house, at or near the junction of the forks of the Kuskokwim, and that a government trail had been surveyed and staked from the Iditarod to the Sushitna, passing close to the same point, and that during the present winter road-houses had sprung up along the western portion of it, so that we should not have to make camp again on the way to Iditarod City. All of which Minchúmina John had collected from the people in the cabin, and now presented to me as reason why he should be released from further service. I was loath to let him go until we were actually _at_ the road-house described, but he wanted to go back to the lake for the potlatch then preparing, and said that two days' delay would bar him from the best of the festivities.
