Perrot received his appointment from the Seminary of St. Sulpice, on
Talon's recommendation, but he afterwards applied for and gained a royal
commission, which, as he thought, made him independent of the priests.]

Perrot, through his wife's uncle, had obtained a grant of the Island above
Montreal, which still bears his name. Here he established a trading house
which he placed in charge of an agent, one Brucy, who, by a tempting
display of merchandise and liquors, intercepted the Indians on their
yearly descent to trade with the French, and thus got possession of their
furs, in anticipation of the market of Montreal. Not satisfied with this,
Perrot, in defiance of the royal order, sent men into the woods to trade
with the Indians in their villages, and it is said even used his soldiers
for this purpose, under cover of pretended desertion. [Footnote: The
original papers relating to the accusations against Perrot are still
preserved in the ancient records of Montreal.] The rage of the merchants
of Montreal may readily be conceived, and when Frontenac heard of the
behavior of his subordinate he was duly incensed.

It seems, however, to have occurred, or to have been suggested to him,
that he, the Governor-General might repeat the device of Perrot on a
larger scale and with more profitable results. By establishing a fortified
trading post on Lake Ontario, the whole trade of the upper country might
be engrossed, with the exception of that portion of it which descended by
the river Ottawa, and even this might in good part be diverted from its
former channel. At the same time, a plan of a fort on Lake Ontario might
be made to appear as of great importance to the welfare of the colony; and
in fact, from one point of view, it actually was so. Courcelles, the late
governor, had already pointed out its advantages. Such a fort would watch
and hold in check the Iroquois, the worst enemy of Canada; and, with the
aid of a few small vessels, it would intercept the trade which the upper
