With eighteen hours of the daylight, and no frost in the summer, vegetation is rapid. In a country where you can ripen Indian corn you can grow practically anything. Mr. McInnes explained that he could not closely indicate the isothermal line on the part of the country he had explored the previous year, but he could say that the country averaged in the summer months from four to five degrees higher temperature than the same latitude farther west. He thought that THE ISOTHERMAL LINE which would go past the north end of the country he had been speaking of, would come down as far as the north shore of Lake Superior, which would be a very long distance south. He had records kept during all summer of the temperatures through that western country, and he had a summary of the record kept in the preceding summers. He was rather surprised at the warmth of that western country in summer, and at the way heat kept up in the evenings. He kept the thermometer readings morning, noon and six o’clock in the evening, and found the six o’clock temperatures were almost as warm as the noon temperatures. That country has a very long day in summer. The day in those high latitudes is very much longer, and the growing time proportionately longer. In June they have about eighteen hours of daylight. As to the district where he found the one hundred and seventy miles of agricultural land he had described, he reached there only about the middle of June. There was no frost in the balance of June or in July, and no frost in August, excepting once, on, he thought, the 29th, when the thermometer dropped just to freezing point. There was not enough frost to touch vegetation at all in the valley of the river where he was. He noticed when he got out to the Saskatchewan there was rather a high ridge on which there were a lot of half-breed settlers. He got there on September 6, and noticed on top of the hills where they had potatoes that they had been touched just on the tops, but down in the villages the potatoes in the garden of the Hudson’s Bay post had not been touched at all. He presumed that was the frost on August 29. Owen O’Sullivan, C.E., of the Geological Survey of Canada, was one of the witnesses before the Senate committee of 1907. He explained that in 1904 he was engaged as assistant to Mr. Wilson in examining the west coast of James bay. They went up the river Kapiskau for one hundred and fifty miles and surveyed it, and found mostly swampy ground, right to about the headwaters of the Kapiskau, longitude 86°. His impression was that the whole coast from the southern extremity of James bay, at the mouth of the Hurricane, up to Cape Henrietta Maria, for an average of one hundred miles in depth, is mostly swampy ground. It is partly peat and wet spagnol (wet moss). There is a bluff of small spruce isolated here and there.
