Jarvis set forth the situation to Mr. W. T. Lopp, the superintendent, adding that he considered Lopp's personal services to be indispensable, as he knew the country, was familiar with the customs and characteristics of the natives, and was expert in handling deer. Lopp replied that "the reindeer had been builded on by his people as their wealth and support, and to lose them would make a break in the work that could not be repaired. Still, in the interests of humanity he would give them all, explain the case to the Eskimos, and induce them to give their deer also [aggregating about three hundred]." Lopp also gave his own knowledge, influence, and personal service, his wife, with a noble disregard for her own comfort and safety at being left alone with the natives, "urging him to go, believing it to be his duty." It is needless to recite in detail the trials and troubles that daily arose in driving across trackless tundras (the swampy, moss-covered plains), in the darkness of midwinter, this great herd of more than four hundred timid, intractable reindeer. Throughout the eight hundred miles of travel the reindeer drivers had to carefully avoid the immediate neighborhood of Eskimo villages for fear of the ravenous, attacking dogs, who, however, on one occasion succeeded in stampeding the whole herd. For days at a time the herders were at their wits' ends to guard the deer against gaunt packs of ravenous wolves, who kept on their trail and, despite their utmost vigilance, succeeded in killing and maiming several deer. A triumphal but venturesome feat of Lopp's was the driving of the herd across the sea-floes of the broad expanse of Kotzebue Sound, thus saving one hundred and fifty miles of land travel and two weeks of valuable time. While there were eight skilled herders, Lapps and Eskimos, the most effective work was that done by a little Lapp deer-dog, who circled around the herd when on the march to prevent the deer from straying. If a deer started from the main herd the dog was at once on his trail, snapping at his heels and turning him toward the others. Very few deer strayed or were lost, and three hundred and sixty-two were brought to Barrow in good condition. Travelling in advance, following the shore line by dog-sledge, Jarvis and McCall were welcomed with warm generosity even by the most forlorn and wretched Eskimos, who asked them into their huts, cared for their dogs, dried their clothes, and did all possible for their safety and comfort. The relief party, however, suffered much from the begging demands of almost starving natives, from the loss of straying dogs, and the desertion of several unreliable native employees. They were quite at the end of their food when they reached, at Cape Krusenstern, their depot. This had been brought up across country from Unalaklik through the great energy and indomitable courage of Bertholf, whose journey and sufferings were no less striking than those of his comrades.
