It will no doubt be remarked that so far very little has been said with reference to arable land and agriculture in that section of the territory to which this chapter is devoted, east of the actual valley of Mackenzie river itself. This is easily explained. In the first place, except at Fort Rae on the north arm of Great Slave lake, no attempts at practical agriculture have been made in the eastern division of the region being treated of, for there are no posts there. Fort Confidence and Fort Franklin on Great Bear lake, and Fort Enterprise near the head waters of the Coppermine, were never ordinary trading posts, being merely winter headquarters, deserted by their tenants as soon as travelling was practicable. [Illustration: Staff and pupils, Church of England Mission, Hay river.] In the second place, the question of the country’s agricultural possibilities have not been considered by the few lightly equipped explorers who have hurried through sections of it intent upon some special mission or other. The only references we find in the journals of such travellers as have ventured through this region in summer, are such as we get in Mr. Preble’s account of his trip via the lake, river and portage route from Great Slave lake to Great Bear lake, when he states that on August 24 “Currants (_Ribes rubrum_ and _prostratum_) were abundant and ripe” along the route. Doctor Richardson (See p. 13), commenting upon the observations made by himself and colleagues of the Franklin expedition at Fort Franklin at the southwest corner of Great Bear lake, gives the following notes regarding the progression of the seasons:—“The relative temperatures of December, January, and February differ considerably; any one of these months may be the coldest in different years. In some years snow exposed to the sun thaws very slightly during these months; in other winters there is no thaw whatever. The snow attains its greatest depth, about three feet, in March. By April 10, the snow begins to thaw decidedly in the sunshine. From May 1 to May 6, the earlier waterfowl arrive. The small streams break up about May 10 or 12. Between the middle and the end of May, most of the small birds arrive. At the end of May or early in June, the earlier shrubs and herbaceous plants flower and sprout their leaves. Frogs are heard at the same time. By the last week of May there is BRIGHT LIGHT AT MIDNIGHT.
