It is a compact among merchants. Its beginning being an accident to trade, and arose from the disease of men’s tempers, who, having run larger adventures in a single bottom than afterwards they found convenient, grew fearful and uneasy; and discovering their uneasiness to others, who perhaps had no effects in the same vessel, they offer to bear part of the hazard for part of the profit: convenience made this a custom, and custom brought it into a method, till at last it becomes a trade. I cannot question the lawfulness of it, since all risk in trade is for gain, and when I am necessitated to have a greater cargo of goods in such or such a bottom than my stock can afford to lose, another may surely offer to go a part with me; and as it is just if I give another part of the gain, he should run part of the risk, so it is as just that if he runs part of my risk, he should have part of the gain. Some object the disparity of the premium to the hazard, when the insurer runs the risk of £100 on the seas from Jamaica to London for 40s., which, say they, is preposterous and unequal. Though this objection is hardly worth answering to men of business, yet it looks something fair to them that know no better; and for the information of such, I trouble the reader with a few heads: First, they must consider the insurer is out no stock. Secondly, it is but one risk the insurer runs; whereas the assured has had a risk out, a risk of debts abroad, a risk of a market, and a risk of his factor, and has a risk of a market to come, and therefore ought to have an answerable profit. Thirdly, if it has been a trading voyage, perhaps the adventurer has paid three or four such premiums, which sometimes make the insurer clear more by a voyage than the merchant. I myself have paid £100 insurances in those small premiums on a voyage I have not gotten £50 by; and I suppose I am not the first that has done so either. This way of assuring has also, as other arts of trade have, suffered some improvement (if I may be allowed that term) in our age; and the first step upon it was an insurance office for houses, to insure them from fire. Common fame gives the project to Dr. Barebone—a man, I suppose, better known as a builder than a physician. Whether it were his, or whose it was, I do not inquire; it was settled on a fund of ground rents, to answer in case of loss, and met with very good acceptance. But it was soon followed by another, by way of friendly society, where all who subscribe pay their quota to build up any man’s house who is a contributor, if it shall happen to be burnt. I won’t decide which is the best, or which succeeded best, but I believe the latter brings in most money to the contriver.
