Their exclusive charter has not been confirmed by Act of Parliament. The South Sea Company, as long as they continued to be a trading company, had an exclusive privilege confirmed by Act of Parliament; as have likewise the present United Company of Merchants trading to the East Indies.

The Royal African Company soon found that they could not maintain the competition against private adventurers, whom, notwithstanding the Declaration of Rights, they continued for some time to call interlopers, and to persecute as such. In 1698, however, the private adventurers were subjected to a duty of ten per cent upon almost all the different branches of their trade, to be employed by the company in the maintenance of their forts and garrisons But, notwithstanding this heavy tax, the company were still unable to maintain the competition. Their stock and credit gradually declined. In 1712, their debts had become so great that a particular Act of Parliament was thought necessary, both for their security and for that of their creditors. It was enacted that the resolution of two-thirds of these creditors in number and value should bind the rest, both with regard to the time which should be allowed to the company for the payment of their debts, and with regard to any other agreement which it might be thought proper to make with them concerning those debts. In 1730, their affairs were in so great disorder that they were altogether incapable of maintaining their forts and garrisons, the sole purpose and pretext of their institution. From that year, till their final dissolution, the Parliament judged it necessary to allow the annual sum of ten thousand pounds for that purpose. In 1732, after having been for many years losers by the trade of carrying negroes to the West Indies, they at last resolved to give it up altogether; to sell to the private traders to America the negroes which they purchased upon the coast; and to employ their servants in a trade to the inland parts of Africa for gold dust, elephants' teeth, dyeing drugs, etc. But their success in this more confined trade was not greater than in their former extensive one. Their affairs continued to go gradually to decline, till at last, being in every respect a bankrupt company, they were dissolved by Act of Parliament, and their forts and garrisons vested in the present regulated company of merchants trading to Africa. Before the erection of the Royal African Company, there had been three other joint stock companies successively established, one after another, for the African trade. They were all equally unsuccessful. They all, however, had exclusive charters, which, though not confirmed by Act of Parliament, were in those days supposed to convey a real exclusive privilege.

The Hudson's Bay Company, before their misfortunes in the late war, had been much more fortunate than the Royal African Company. Their necessary expense is much smaller. The whole number of people whom they maintain in their different settlements and habitations, which they have honoured with the name of forts, is said not to exceed a hundred and twenty persons. This number, however, is sufficient to prepare beforehand the cargo of furs and other goods necessary for loading their ships, which, on account of the ice, can seldom remain above six or eight weeks in those seas. This advantage of having a cargo ready prepared could not for several years be acquired by private adventurers, and without it there seems to be no possibility of trading to Hudson's Bay. The moderate capital of the company, which, it is said, does not exceed one hundred and ten thousand pounds, may besides be sufficient to enable them to engross the whole, or almost the whole, trade and surplus produce of the miserable, though extensive country, comprehended within their charter. No private adventurers, accordingly, have ever attempted to trade to that country in competition with them. This company, therefore, have always enjoyed an exclusive trade in fact, though they may have no right to it in law. Over and above all this, the moderate capital of this company is said to be divided among a very small number of proprietors. But a joint stock company, consisting of a small number of proprietors, with a moderate capital, approaches very nearly to the nature of a private copartnery, and may be capable of nearly the same degree of vigilance and attention. It is not to be wondered at, therefore, if, in consequence of these different advantages, the Hudson's Bay Company had, before the late war, been able to carry on their trade with a considerable degree of success. It does not seem probable, however, that their profits ever approached to what the late Mr. Dobbs imagined them. A much more sober and judicious writer, Mr. Anderson, author of The Historical and Chronological Deduction of Commerce, very justly observes that, upon examining the accounts of which Mr. Dobbs himself was given for several years together of their exports and imports, and upon making proper allowances for their extraordinary risk and expense, it does not appear that their profits deserve to be envied, or that they can much, if at all, exceed the ordinary profits of trade.
