pasture”, and regarded as suitable for settlement. The population density on the prairies is thus about one person for every 41-5 cultivable acres. On this basis, the North Pacific Region, with its 15,400,000 acres of cultivable land, should support a population of about 375,000 in order to bring it up to the same density of population as prevails on the prairies. The present population of the Region, as computed, is about 110,000, which is 265,000 less than the potential total. Here it should be made clear that this 375,000 popula- tion, as forecast, is not all agricultural population, the assumption having been that mining and other industrial developments will be similar in magnitude to those in the Prairie Provinces, where the manufacturing industry and the exploitation of the oil, coal, and other mineral resources have become an important part of western economy. Agricultural land has been taken as the yardstick, being the only measure available. Calculated in another way, the 1941 Census of Agri culture indicates that the total area of occupied farm land in the census areas within the Region is between 3,500,000 acres and 3,700,000 acres. Subtraction of the higher figure from the computed total of 15,400,000 acres of agricultural land suited to settlement leaves 11,700,000 acres of land in the same category. On the basis of 1 person to 41-5 acres of occupied farm land, as obtains in the Prairie Provinces, these 11,700,000 acres would support a population of about 282,000. It is, therefore, concluded that between 265,000 and 282,000 would be a reasonable forecast of the population that may be expected normally to settle in the Region within the discernible future, and under such conditions as can be at present foreseen. Addition of the 110,000 people now in the Region would indicate a total population of 375,000 to 390,000. In view of the very conservative basis on which this estimate has been developed and the large areas for which the economic potential cannot be even roughly appraised, we may be justified in forecasting a population of 400,000, to bring to prairie level, for the North Pacific Region in the discernible future. On this point, it might be mentioned that in 1911 there were less than 2,000 people, including — traders, missionaries, and Indians, in the Peace River Valley. The railway penetrated the district in 1916. By 1921, the population had reached 20,000, and in 1931 it was about 60,000. Today, with 66,000 people, only 3,500,000 acres, or about one-third of the district’s cultivable land suited to settlement, are occupied and, according to the 1941 Census, only 1,430,000 acres, or about one-seventh, are improved. Very little is known of the character of the soils in the Mackenzie Valley below Great Slave Lake. Only small areas about the trading posts have been cultivated. The valley lies within the sub-Arctic forest zone, which is characterized by light rainfall and, except close to the rivers, poor drainage. These factors, together with the presence of permanent frost near the surface, would appear to make farming an uncertain occupation. Soil and climate indicate that agricultural settlement may push as far north as Simpson. The valley of the Liard has been reported as subject to chinook influence and its climate has been favourably compared with that of the Peace. Reports on the Hay River Valley have been variable. Information as to the soil indicates a large proportion of swamps and muskegs, which may later repay draining. Some favourable references have been made to areas in the eastern section of Wood Buffalo Park. The fact is that no comprehensive information is available concerning the large area embraced by the drainage basins of the Nelson, Liard, Hay, and Mackenzie Rivers. It is a characteristic of the northern agricultural fringe that much of the good land does not occur in large blocks, but is interspersed with a high proportion of poor land. Even to the south, in the soil-survey areas between Fort Vermilion and Hay River, it was found that not more than 20 per cent of the area could be regarded as suitable for agricultural settlement. Although this presents a rather dark picture of the possi- bilities for agricultural settlement in the Mackenzie and tributary valleys, there are certain factors that favour a moderate degree of agricultural development in this area. Along the Slave River and the southern shores of Great Slave Lake, cereals, hay, potatoes, and garden vegetables can be produced. The lower Hay River has agricultural possibilities and the lower Liard River, the favourable features of which have been particularly mentioned in some reports, comes within the line established as marking the limit of Western Canada’s agricultural belt. For the most part, these areas are forested—in some localities, heavily— and clearing would involve heavy expense. It would appear that the exploitation of such areas would be limited by the local requirements for such crops as can be economi- cally produced. In the northern part of the Region lie the sub-Arctic prairies. It has been said that they will carry settlement as far as grass grows and that domestic cattle, if sheltered through the coldest weather and protected from flies, will thrive on these grazing lands. Much has been written about the extensive ranges for the year-round grazing of reindeer in the Great Bear Lake district; in some cases, the inference has been that a limited commercial develop- ment of reindeer herds might be undertaken. The Dominion of Canada, in the vast extent and diversi- fication of its agricultural lands, offers many millions of acres of greater promise for grazing animal herds than those hinterlands. Certain species indigenous to the area, notably the reindeer, thrive on these barrens, and every effort is being made to increase their range and numbers, primarily for the preservation and development of the human values in the northern aboriginal population. Quite apart from humanitarian considerations, it seems [45 ]
