willing to exchange ample supplies of corn for tobacco and firearms.
The Huron slaves who carried the corn to the fort acted as spies among
the Mohawks for the French.

In the month of February the vague rumors of conspiracy crystallized
into terrible reality. A dying Mohawk confessed to a Jesuit that the
Iroquois[4] Council had determined to massacre half the company of

They at once began constructing two large flat-bottomed boats of light
