Two factors immediately began to play a most important part in the agricultural situation: the opening up of the north-western lands by the completion of the Canadian Pacific Railway in 1886, and the enactment, on October 6, 1890, of the McKinley high tariff by the United States. The former attracted Ontario's surplus population, and made it no longer profitable or desirable to grow wheat in the province for export; the latter closed the doors to the export of barley, live stock, butter, and eggs. The situation was desperate; agriculture was passing through a period of most trying experience. Any other industry than that of agriculture would have been bankrupted. The only hope of the Ontario farmer now was in the British market. The sales of one Ontario product, factory cheese, had been steadily increasing in the great consuming districts of England and Scotland, and there was reason to believe that other products might be sold to equal advantage. Dairying was the one line of agricultural work that helped to tide over the situation in the early nineties. The methods that had succeeded in building up the cheese industry must be applied to other lines, and all the organized forces must be co-ordinated in carrying this out. This was work for a department of Agriculture, and the minister of Agriculture, John Dryden, who guided and directed this co-operation of forces and made plans for the future growth and expansion of agricultural work, was an imperialist indeed who, in days of depression and difficulty, directed forces and devised plans that not only helped the agricultural classes to recover their prosperity, but also made for the strengthening of imperial ties and the working out of national greatness.
