Statistics from the Department of the Interior of Canada show that there were in Canada in 1900, water power developments to the extent of 200,000 H.P.; in 1910, 900,000 H.P.; in 1920, 2,500,000 H.P.; and in 1936, 7,909,000 H.P. The estimated capital invested in water power developments in 1936 was $1,890,000,000.00. Further possible additional developments in Canada amount to 28,000,000 H.P. Water power developments in the Province of Quebec have grown in about the same proportion as the whole of Canada and total today 3,853,000 H.P. which represent about 25 per cent of the water powers available for developments in the province. The development of water powers in Canada was just beginning in 1900, the rapid strides in the following years have shown the legislators of the Province of Quebec the necessity of a thorough study of the resources under their jurisdiction. In 1910, a law was passed creating the Quebec Streams Commission, said Commission to be composed of three members and to be guided in its duties by the following articles: 1.
