The women attended to all the business of sugar manufacture, while the men cut wood and went out hunting and fishing to secure food for the community; though, as a matter of fact, sugar and syrup were their main sustenance during all this absence from home. "I have known Indians", wrote Henry, "to live for a time wholly on maple sugar and syrup and become fat." The sap of the maple had certain medicinal qualities which were exceedingly good for persons who had previously been eating little else than meat and fish, so that the three weeks of sugar-boiling in Canada was, no doubt, a splendid assistance to the health of the natives. On this particular occasion described by Henry, the party returned, after three weeks' absence, to the Sault Ste Marie with 1600 lb. of maple sugar, and 36 gallons of syrup.[4]
[Footnote 4: There are at least two species of maple in Canada yielding sugar from their sap; but the best is _Acer saccharinum_. The maple leaf is the national emblem of Canada.]
Henry returned in the summer of 1763 to Fort Michili-makinak. The place was then held by a British garrison under Major Etherington. Shortly after Henry's arrival, an Ojibwé chief named Wáwátam came often to his lodgings, and, taking a great fancy to the Englishman, asked leave to become his blood brother. He was about forty-five years of age, and of an excellent character amongst his nation. He warned Henry that he, Wáwátam, had had bad dreams during the winter, in which he had been disturbed "by the noises of evil birds", and gave him other roundabout warnings that the Indians of different tribes were going to attack the British garrison at Michili-Makinak, and endeavour to destroy all the English in Upper Canada. Henry did not pay over much attention to this warning, because "the Indian manner of speech is so extravagantly figurative".
The King's birthday was celebrated with, no doubt, somewhat tipsy rejoicings in the summer of 1763. The Ojibwé Indians outside the fort pretended they were going to have a great game of La Crosse with the S[¯a]ki or "Fox" Indians. This game was got up to find a pretext for entering the fort and taking the British officers and garrison at a disadvantage. Some of the officers and soldiers, suspecting nothing in the way of danger, were outside the fort by the waterside. However, the sport commenced, and suddenly the ball was struck over the pickets of the fort. At once the Ojibwés, pretending great ardour in their game, came leaping, struggling and shouting over the defences into the fort as though "in the unrestrained pursuit of a rude, athletic exercise". Once inside the fortifications, they attacked the unsuspicious and unarmed soldiers and officers, of whom they killed seventy out of ninety.
