The whole interior of the northern part of the United States have relied, and still rely, more on their maple woodlands for sugar than on any other source; and as a branch of domestic manufacture and home production, the business is of no little consequence. The time occupied too in the manufacture is very limited, and occurs at a season when very little other labor can be performed. Hitherto but comparatively little attention has been bestowed upon this important branch of industry in Canada. The inhabitants of that province might doubtless manufacture a sufficient quantity of maple sugar to supply the demand or consumption in this article for the whole population of the country. This variety of sugar may be refined, and made as valuable for table use as the finest qualities of West India sugar. On the south shore of Lake Huron, and the islands of that inland sea, there are forests of sugar maple unsurveyed capable of producing a supply for the whole population. The Indians upon those islands have lately turned their attention pretty largely to the manufacture of sugar from the maple; and many tons have been exported from this source. If the Indians could obtain a fair value for their sugar, say seven or eight dollars per 100 lbs., they would extend their operations upon a large scale. Upon these islands alone, there are upwards of a million of full-grown maple trees, capable of yielding each from two and a half to three pounds of excellent sugar per annum; and if proper attention were given to this branch of production in that quarter, I see no reason why a most profitable business could not be carried on. Every farmer who has a grove of sugar maple, should endeavour to manufacture at least sufficient for the consumption of his own family. In most cases 150 trees of medium growth would yield an amount of sap that would make 300 lbs. of sugar, twenty-five gallons of molasses, and a barrel of vinegar. The labor required to manufacture this amount of sugar, molasses, and vinegar, would scarcely be felt by the well-organised cultivator, as the season for the business is at the close of the winter, and opening spring, when no labor can be done upon the land. In proportion to the amount of labor and money expended in the production of maple sugar, it is as capable of yielding as large a return of profits as any other branch of farm business. It is certainly an object of great national interest to the inhabitants of our North American Colonies, that they should supply their own market with such products as their highly-favored country is capable of producing. Sugar is an article which will ever find a ready sale at highly-remunerating prices, provided that it be properly manufactured and brought into market in good condition. It requires a little outlay at first to purchase buckets, cisterns, and boilers, to stock a sugar bush; but by carefully using the above necessary apparatus, they will last for a very long period.
