Mackenzie had reached the goal of his endeavours. His followers, when they learned that the open sea, the _mer d'ouest_ as they called it, was in sight, were transformed; instead of sullen ill-will they manifested the highest degree of confidence and eager expectation. They declared their readiness to follow their leader wherever he wished to go, and begged that he would not turn back without actually reaching the shore of the unknown sea. But in reality they had already reached it. That evening, when their camp was pitched and they were about to retire to sleep, under the full light of the unsinking sun, the inrush of the Arctic tide, threatening to swamp their baggage and drown out their tents, proved beyond all doubt that they were now actually on the shore of the ocean. For three days Mackenzie remained beside the Arctic ocean. Heavy gales blew in from {86} the north-west, and in the open water to the westward whales were seen. Mackenzie and his men, in their exultation at this final proof of their whereabouts, were rash enough to start in pursuit in a canoe. Fortunately, a thick curtain of fog fell on the ocean and terminated the chase. In memory of the occurrence, Mackenzie called his island Whale Island. On the morning of July 14, 1789, Mackenzie, convinced that his search had succeeded, ordered a post to be erected on the island beside his tents, on which he carved the latitude as he had calculated it (69 deg. 14' north), his own name, the number of persons who were with him and the time that was spent there. This day Mackenzie spent in camp, for a great gale, blowing with rain and bitter cold, made it hazardous to embark. But on the next morning the canoes were headed for the south, and the return journey was begun. It was time indeed. Only about five hundred pounds weight of supplies was now left in the canoes--enough, it was calculated, to suffice for about twelve days. As the return journey might well occupy as many weeks, the fate of the voyageurs must now depend on the chances of fishing and the chase. {87}
