In a communication to the press in 1910, Mr. Ogilvie wrote:—“From Fort Vermilion to Fort Liard on Liard river, where wheat has been successfully grown for more years than many people would credit, is three hundred and ten miles; by trail, say three hundred and fifty. On this stretch just across Peace river Hay river prairies are highly spoken of, and certainly look well from the river. A railway line would probably follow down Black river valley to Liard, and extensive meadows in this valley were reported by natives when I was there in 1891.” EVIDENCE BEFORE THE LATE SENATE COMMITTEE. The select committee of the Senate of Canada which sat in 1907 devoted considerable attention to the agricultural possibilities of Mackenzie valley. Mr. R. G. McConnell of the Geological Survey was examined before the committee and said he did not happen to be in places where there was any farming going on, but was at Fort Providence in the autumn and wintered there one winter, and ate potatoes, turnips and other vegetables like that all winter that had been grown there. That is north of Great Slave lake. Going down the Mackenzie, Mr. McConnell explained, once you get away from the river flat you get into a rolling country partly with muskeg, with hard ridges between. The only possible part of that country suitable for agriculture, he thought, would be the large flats down Mackenzie river. It is a wide valley, but there is the same thing there: you never know exactly beforehand what is going to happen. Certainly it does not look like a favourable country for agriculture once you get away from the river. The prairie on Liard river is a little north of the 60th degree of latitude. There is a lot of marsh hay growing around Great Slave lake. It would be good for feeding stock. Along Great Slave lake itself there is a large tract of flat country which may come in some time. Most of the grass Mr. McConnell saw there was a heavy marsh grass. It is not jointed, though there is some of that kind. He remembered seeing patches of it on Hay river. Asked as to the extent of good agricultural land in the country, Mr. McConnell said it depended on what was called good agricultural country. He knew that at Fort Good Hope, right down on the circle, they can raise good potatoes, because he saw them, and there is no reason why they cannot raise vegetables all the way down the Mackenzie as far north as that. The land on both sides of the river suitable for agriculture does not extend far. There are flats two or three miles wide—bottom flats of the Mackenzie a mile to a mile and a half wide. Once you get up out of the valley the country is rolling and partly muskeg. There is a large tract of that sort of country extending as far north as Fort Good Hope. It is about a thousand miles altogether from Great Slave lake to the sea, and that flat would be six or eight hundred miles in length. INTENSE SUMMER HEAT.
