But these evils were in due course of years surmounted, and in the year 1831, when an estimate of the possessions of the Canadians was made, the result disclosed an amount of successful industry for which the world had not given them credit. During the seventy years which had elapsed since England conquered the valley of the St. Lawrence, the population had increased from sixty thousand to nearly nine hundred thousand. With the addition of Nova Scotia, New Brunswick, and the smaller colonies, the American subjects of England numbered now a million and a quarter. The lands which their toil had redeemed from wilderness were now valued at seventeen million sterling. Their cattle and horses were worth seven million; their dwellings and public buildings had cost them fifteen million; they had two million invested in the machinery by which the timber of their boundless forests was prepared for market; in their great cod and seal fisheries they had a fixed capital of a million and a half. Eight hundred ships annually visited their ports from Great Britain; in all the branches of their maritime industry two thousand five hundred arrivals were registered. They received every year foreign or colonial goods to the value of two million; and they exported to a somewhat larger extent. They built ships, and sold them to England; they sent many cargoes of timber, and much valuable fur; already they produced food beyond their own consumption, and they sent to Europe wheat and flour and oats and salted provisions. They shipped fish and fish oils. They burned down masses of their abundant timber, and having obtained the salts which combustion set free, they manufactured them into pot and pearl ashes, and shipped them to Europe for service in bleaching and other operations. They supplied themselves with sugar from the sap of their maple trees. They brewed much excellent cider and beer; they distilled from rye, potatoes, apples, much whisky which was not excellent.
