On July 4, provisions were cached, the canoe abandoned, and a start made overland westward, each carrying ninety pounds of provisions besides musket and pistols. And this burden was borne on the rations of two scant meals a day. The way was ridgy, steep, and obstructed by windfalls. At cloud-line, the rocks were slippery as glass from moisture, and Mackenzie led the way, beating the drip from the branches as they marched. The record was twelve miles the first day. When it rained, the shelter was a piece of oil-cloth held up in an extemporized tent, the men crouching to sleep as best they could. The way was well beaten and camp was frequently made for the night with strange Indians, from whom fresh guides were hired; but when he did not camp with the natives, Mackenzie watched his guide by sleeping with him. Though the fellow was malodorous from fish oil and infested with vermin, Mackenzie would spread his cloak in such a way that escape was impossible without awakening himself. No sentry was kept at night. All hands were too deadly tired from the day's climb. Once, in the impenetrable gloom of the midnight forest, Mackenzie was awakened by a plaintive chant in a kind of unearthly music. A tribe was engaged in religious devotions to some woodland deity. Totem poles of cedar, carved with the heads of animals emblematic of family clans, told Mackenzie that he was nearing the coast tribes. Barefooted, with ankles swollen and clothes torn to shreds, they had crossed the last range of mountains within two weeks of leaving the inland river. They now embarked with some natives for the sea.
One can guess how Mackenzie's heart thrilled as they swept down the swift river—six miles an hour—past fishing weirs and Indian camps, till at last, far out between the mountains, he descried the narrow arm of the blue, limitless sea. The canoe leaked like a sieve; but what did that matter? At eight o'clock on the morning of Saturday, July 20, the river carried them to a wide lagoon, lapped by a tide, with the seaweed waving for miles along the shore. Morning fog still lay on the far-billowing ocean. Sea otters tumbled over the slimy rocks with discordant cries. Gulls darted overhead; and past the canoe dived the great floundering grampus. There was no mistaking. This was the sea—the Western Sea, that for three hundred years had baffled all search overland, and led the world's greatest explorers on a chase of a will-o'-the-wisp. What Cartier and La Salle and La Vérendrye failed to do, Mackenzie had accomplished.
But Mackenzie's position was not to be envied. Ten starving men on a barbarous coast had exactly twenty pounds of pemmican, fifteen of rice, six of flour. Of ammunition there was scarcely any. Between home and their leaky canoe lay half a continent of wilderness and mountains. The next day was spent coasting the cove for a place to take observations. Canoes of savages met the white men, and one impudent fellow kept whining out that he had once been shot at by men of Mackenzie's color. Mackenzie took refuge for the night on an isolated rock which was barely large enough for his party to gain a foothold. The savages hung about pestering the boatmen for gifts. Two white men kept guard, while the rest slept. On Monday, when Mackenzie was setting up his instruments, his young Indian guide came, foaming at the mouth from terror, with news that the coast tribes were to attack the white men by hurling spears at the unsheltered rock. The boatmen lost their heads and were for instant flight, anywhere, everywhere, in a leaky canoe that would have foundered a mile out at sea. Mackenzie did not stir, but ordered fusees primed and the canoe gummed. Mixing up a pot of vermilion, he painted in large letters on the face of the rock where they had passed the night:—
"Alexander Mackenzie, from Canada, by land, the twenty-second of July, one thousand seven hundred and ninety-three."
The canoe was then headed eastward for the homeward trip. Only once was the explorer in great danger on his return. It was just as the canoe was leaving tide-water for the river. The young Indian guide led him full tilt into the village of hostiles that had besieged the rock. Mackenzie was alone, his men following with the baggage. Barely had he reached the woods when two savages sprang out, with daggers in hand ready to strike. Quick as a flash, Mackenzie quietly raised his gun. They dropped back; but he was surrounded by a horde led by the impudent chief of the attack on the rock the first night on the sea. One warrior grasped Mackenzie from behind. In the scuffle hat and cloak came off; but Mackenzie shook himself free, got his sword out, and succeeded in holding the shouting rabble at bay till his men came. Then such was his rage at the indignity that he ordered his followers in line with loaded fusees, marched to the village, demanded the return of the hat and cloak, and obtained a peace-offering of fish as well. The Indians knew the power of firearms, and fell at his feet in contrition. Mackenzie named this camp Rascal Village.
At another time his men lost heart so completely over the difficulties ahead that they threw everything they were carrying into the river. Mackenzie patiently sat on a stone till they had recovered from their panic. Then he reasoned and coaxed and dragooned them into the spirit of courage that at last brought them safely over mountain and through cañon to Peace River. On August 24, a sharp bend in the river showed them the little home fort which they had left four months before. The joy of the voyageurs fairly exploded. They beat their paddles on the canoe, fired off all the ammunition that remained, waved flags, and set the cliffs ringing with shouts.
Mackenzie spent the following winter at Chipewyan, despondent and lonely. "What a situation, starving and alone!" he writes to his cousin. The hard life was beginning to wear down the dauntless spirit. "I spend the greater part of my time in vague speculations.… In fact my mind was never at ease, nor could I bend it to my wishes. Though I am not superstitious, my dreams cause me great annoyance. I scarcely close my eyes without finding myself in company with the dead."
The following winter Mackenzie left the West never to return. The story of his travels was published early in the nineteenth century, and he was knighted by the English king. The remainder of his life was spent quietly on an estate in Scotland, where he died in 1820.
