  Kashnor notes, [quoted directly from the map] "It may be proper to inform the curious, that in laying down the Geography of Hudson's Bay and the Neighboring Coasts, &c., we have consulted and in some respects followed Capt. Middleton's Draught: But more particularly that of Capt Smith and the Officers of the Furnace Sloop and Discovery Pink from 52 to 67 North Latitude. We have also perused, and derived some assistance from a Chart of these parts lately published, Dedicated to Arthur Dobbs Esqr. The Authorities here referred to, are ye most authentick yet Extant: but the public is in great Expectation of New Discoveries from the Expedition of the Dobbs Galley and the California which passed Yarmouth the 31st of May 1746 under convoy of the Loo of 40 Guns, on their Voyage to Discover the N.

  A Map of North America with Hudson's Bay and Straits, Anno 1748

  Visual Materials

  Kashnor notes, "THE ONLY COPY KNOWN, and privately issued by the Hudson's Bay Company. The main cause of this issue was the controversy concerning the alleged neglect of the Company to further the exploration for a North-West Passage. Arthur Dobbs was the leader of this opposition, and he hoped by proving the neglect, to see the company loose its privileges under the charter. Middleton, formerly a servant of the Company, had been sent to find the Passage, but had returned beaten, with the firm conviction that even if the passage did exist, it was impractical. This was in 1741-42. Dobbs, still unshaken, formed a company, which, with the thought of rights of exclusive trade, sent out the Dobbs Galley and the California in 1746. In October 1747, the two vessels returned to the Thames, the expedition a failure. In the following year the opposition to the company resulted in the Parliamentary Inquiry into the rights and working of the Company's charter. This map was part of the Company's case. There is no doubt that Seale, the engraver, executed the work according to the idea of the Company's officers, rather than following the true lines of geographical knowledge, which was available even in Middleton's map. Either the Company was very ignorant, or ready to connive at producing a fraudulent map. Around the Bay there is no outlet of any kind, and Sir Thomas Lancaster's Sound is located on the western side of the continent. The obvious intention of the map was to prove that the Passage went by way of the St. Lawrence, through the Great Lakes to Machilmakinac, where a junction was formed with the Long River of La Hontan, which gained by a portage across an isthmus, another portage from Tahnglak of La Hontan reached the Western Sea. In the Pacific the northern land seen by Vasco de Gama is shown touching the North-West coast, and there is shown De Fonte's track going in the direction of Alaska. It is a brilliant piece of geographical imagination, and yet the coastlines and locations of the Bay are correct. It seems likely that the map, as evidence, was too circumstantial, but it is in keeping with the whole of the inquiry of 1748-49, when the main object was to steer clear of questions regarding the charter, and it is possible that evidence of Joseph la France upset the evidence, and, naturally, the best way was to destroy all copies of the map. In any case, there is no other copy known to be in existence. It is, without doubt, the rarest of engraved maps of America, and unique." Kashnor is incorrect regarding the uniqueness of this map. The archives of the Hudson’s Bay Company at Beaver House, London, possess nine copies; there is another at the company’s Winnipeg headquarters. There is also a copy in the British Museum, presented by the company in 1957. See "The Beaver", Winter 1962, (Huntington F1060.1A1B4) for a full article about this map by Glyndwr Williams.
