Parkman, in a terse sentence, sums up the conditions which fettered all Canadian trade and industry, “A system of authority, monopoly and exclusion in which the government, and not the individual, acted always the foremost part.”  Whether it was a question of ship-building, of a brewery or a tannery, of iron works or a new fishery, appeals must be made in the first instance to the king for aid; and the people were never taught to depend exclusively on their individual or associated enterprise.  At the time of the conquest, and in fact for many years previously, the principal products of the country were beaver skins, timber, agricultural products, fish, fish oil, ginseng (for some years only), beer, cider, rug carpets, homespun cloths—­made chiefly by the inmates of the religious houses—­soap, potash, leather, stoves, tools and other iron manufactures—­made in the St. Maurice forges—­never a profitable industry, whether carried on by companies or the government itself.  All these industries were fostered by the state, but, despite all the encouragement they received, the total value of the exports, principally furs, seal and other oils, lumber, peas, grain and ginseng never exceeded 3,500,000 francs, or about one-tenth of the export trade of the English colonies to Great Britain.  Two-thirds of this amount represented beaver skins, the profits on which were very fluctuating, on account of the unwise regulations by which, the trade was constantly crippled.  This business was heavily taxed to meet the necessities of colonial government, which were always heavy, and could never have been met had it not been for the liberality of the king.  In the year 1755 the amount of all exports did not reach 2,500,000 francs, while the imports were valued at 8,000,000 francs.  These imports represented wines, brandies, hardware and various luxuries, but the bulk was made up of the supplies required for the use of the military and civil authorities.  The whole trade of the country was carried in about thirty sea-going vessels, none of them of heavy tonnage.  The royal government attempted to stimulate ship-building in the country, and a few war vessels were actually built in the course of many years, though it does not appear that this industry was ever conducted with energy or enterprise.  During the last fifty years of French rule, in all probability, not a hundred sea-going vessels were launched in the valley of the St. Lawrence.  Duties of import, before 1748, were only imposed on wines, brandies, and Brazilian tobacco; but after the commencement of the war with England, the king found it necessary to establish export and import duties:  a special exception was however made in favour of the produce of the farm, forest and sea, which were allowed to enter or go out free.  The whole amount of duties raised in ordinary years did not reach above 300,000 francs.
