The survey made by Deputy Surveyor-General Collins, at the request of Lord Dorchester, in 1788, included an examination of the lakes and harbors from Kingston to Michilmicinac. In reference to the lakes and vessels, the Surveyor says:—“Vessels sailing on these waters being seldom for any length of time out of sight of land, the navigation must be considered chiefly as pilotage, to which the use of good natural charts is essential and therefore much wanted. Gales of wind, or squalls, rise suddenly upon the lakes, and from the confined state of the waters, or want of sea-room, (as it is called), vessels may in some degree be considered as upon a lee shore, and this seems to point out the necessity for their being built on such a construction as will best enable them to work to windward. Schooners should, perhaps, have the preference, as being rather safer than sloops, they should be from 80 to 100 tons burthen on Lake Ontario, and 50 tons burthen on Lakes Erie and Huron; but if not intended to communicate between these two lakes, they may then be the same size as on Lake Ontario; and if this system is approved there can be no necessity to deviate from it unless an enemy should build vessels of greater magnitude or force; but as the intent of bringing any such forward, at least the building of them can never remain a secret, there may be always time to counteract such a design by preparing to meet them at least on equal terms. It does not seem advisable, nor do I know any reason to continue the practice of building vessels flat bottomed, or to have very little draft of water, they are always unsafe, and many of the accidents which have happened on the lakes, have perhaps, in some degree been owing to that construction. On the contrary, if they are built on proper principles for burthen as well as sailing they will be safer, and will find sufficient depth of water proportioned to any tonnage which can be requisite for them upon these lakes.”
