There are many people in the Mackenzie district who have given me much valuable information about their country, the greater part of which , however, has to be omitted here, but few men perhaps know the country better than Father Giroux, formerly stationed at Arctic Red River but now in charge of Providence. He says it is true in the Mackenzie district, as it is among the Arctic Eskimo, that measles is the deadliest of all diseases. There have been several epidemics, so that it might be supposed that the most susceptible had been weeded out, and yet the last epidemic (1903) killed about one fifth of the entire population of the Mackenzie Valley . He had noticed also a distinct and universal difference in health between those who wear white men's clothing and who live in white men's houses, as opposed to those who keep the ancient customs in the matter of dress and dwellings. These same elements I have since found equally harmful among the Eskimo, although among them must be added the surely no less dangerous element, the white men's diet, which is no more suited to the people than white men's clothing or houses. 

Grains and vegetables of most kinds, and even strawberries, are successfully cultivated at Providence. North of that, the possible agricultural products get fewer and fewer, until finally the northern limit of successful potato growing is reached near Fort Good Hope, on the Arctic Circle. Potatoes are grown farther north, but they do not mature and are not of good quality. 

In certain things the Mackenzie district was more advanced the better part of a century ago than it is now; the explorers of Franklin's parties, for instance, found milk cows at every Hudson's Bay post and were able to get milk and cream as far north as the Arctic Circle and even beyond. At that time, too, every post had large stores of dried meat and pemmican, so that if you had the good-will of the Company you could always stock up with provisions anywhere. Now this is all changed. Game has become so scarce that it would be difficult for the Company, even if they tried, to keep large stores of meat on hand. The importation of foodstuffs from the outside, on the other hand, has not grown easy as yet, and it is therefore much more difficult to buy provisions now than it was in Franklin's time. The trading posts are located now exactly where Franklin found them, so that taking this into consideration, and the decrease of game all over the northern country, it is clear that exploration on such a plan as ours — that of living on the country —is more difficult now than it was a hundred years ago. Another element that makes the situation more risky is that while then you could count on finding Indians anywhere who could supply you with provisions, or at least give you information as to where game might be found, now there are so few of the Indians left alive , —and all of those left are so concentrated around the trading posts , —that you may go hundreds of miles without seeing a camp or a trail, where seventy-five or a hundred years ago you would have found the trails crossing each other and might have seen the camp smokes rising here and there. 

The food supplies of the different posts vary according to location . In general the trading stations are divided into "fish posts" and “meat posts.” Fort Smith is a typical meat post, for caribou are found in the neighborhood and moose also; and the Indians not only get meat enough for themselves and for the white men, but the fur traders even find the abundance of the meat supply a handicap in their business, - for the Indian who has plenty to eat does not trap so energetically as do others who must pay in fur for some of their food. Resolution, Hay River, and Providence, on the other hand, are fish posts, while at any of the northern trading stations potatoes nowadays play a considerable part in the food supply, even as far up as Good Hope. In certain places and in certain years rabbits are an important article of diet, but even when there is an abundance of this animal, the Indians consider themselves starving if they get nothing else, and fairly enough, as my own party can testify, for any one who is compelled in winter to live for a period of several weeks on lean-meat will actually starve, in this sense: that there are lacking from his diet certain necessary elements, notably fat, and it makes no difference how much he eats, he will be hungry at the end of each meal, and eventually he will lose strength or become actually ill. The Eskimo who have provided themselves in summer with bags of seal oil can carry them into a rabbit country and can live on rabbits satisfactorily for months. The Indian, unfortunately for him, has no animal in his country so richly supplied with fat as is the seal, and nowadays he will make an effort to buy a small quantity of bacon to eat with his rabbits, unless he has a little caribou or moose fat stored up from the previous autumn.
