Spanish and Russian America’ Io! Fournal of Francisco Antonio Maurelle which was published in 1781. Meares’ account of his Voyages came out in 1790, and on 13 May of that year he presented his memorial to the British Parliament in which he recited his case against Spain, claiming the restitution of his ship, his lands and buildings, valued by him at $650,000. He eventually received $210,000. What particularly interested Mackenzie was the account Meares gave of the voyage of the Washington through an immense inland sea east of Vancouver Island, which at that time had not been circumnavigated. This account is prefixed to Meares’ narrative of his voyages under the title “Observations on the Probable Existence of a North-West Passage.” Some of the statements made therein caused a wordy war which was waged in a series of pamphlets between Captain Dixon and Captain Meares. The former’s journal had been published in 1789, and he took issue with Meares on his extravagant statements. This controversy was familiar to Mackenzie as he refers to it in a note. Vancouver sailed from London in January 1791 for Nootka as one of the commissaries appointed to carry out the terms of the Convention. It may be taken for granted that Mackenzie availed himself of all the material published up to that date relating to the North-West Coast. Although he nowhere mentions the fact, he was probably aware that Heceta claimed to have discovered the Rio de San Roque, in latitude 46° 20’ north. Mackenzie’s knowledge of the trade between the North- West Coast and China made it clear to him that it was just as easy to send furs to China direct from the Pacific coast as it was to send them to England from Montreal—in fact, 1 Meares asserts that the Washington “sailed through a sea extend- ing upwards of eight degrees of latitude” east of Vancouver Island.
