Cascade Inlet. It must be a rock which will meet the following conditions: an abandoned village site near-by; a rock suitable for defence and with a sheer face on the south-east side; near an inlet on which is an old Indian village; a southerly exposure for at least three miles; and with a cove lying north-east about three miles distant. The rock which Captain Bishop has located complies exactly with each of these requirements. He has therefore called it ‘“Mackenzie’s Rock,’ as being beyond doubt the rock on which the explorer wrote with a mixture of ver- milion and grease those words, his “ brief memorial” known to every school boy in the country: “Alexander Mackenzie from Canada by land the twenty-second of July one thousand seven hundred and ninety-three.” His conclusion has been concurred in by the Land Depart- ment of British Columbia, the British Columbia Historical Association, and the Historic Sites and Monuments Board of Canada. Our author's work has also been checked by another surveyor, Mr. J. P. Forde, Resident Engineer of the Public Works Department in Victoria, on the ground and his conclusion affirmed and accepted. That ““Mackenzie’s Rock’’ has been definitely identi- fied will be the opinion of every one who carefully reads the attached paper (which is his official report on the subject) and who studies the route as shown on the map with the aid of Mackenzie’s own account. The Historic Sites and Monuments Board of Canada regards this as one of the most important identifications that has been made in connection with the story of Western Canada. It has therefore determined to give Captain Bishop’s paper a wide publicity by publishing it as a memoir. In conclusion I cannot do better than quote the author's words in an address delivered in Victoria, B.C., upon this subject. Emphasizing the importance of this apparently trivial matter he says: ““There are two important reasons. One is that it marks the first crossing of the continent. All good Canad- ians are well aware of this, but the fact is apparently by no means universally realized. Fiske, in “The Discovery of America,’ solemnly announces that the continent was first crossed by Lewis and Clark, whose expedition reached the Columbia some twelve years later, when the United Page Eight
