Ireland, and part of the coast of Scotland, is laid down from Mr. Mackenzie’s late surveys; and the south coast of England from a chart published by Mr. Faden in 1780, taken from M. l’Abbé Dicquemare.
The north part of the coast of Labradore, from the latitude of 57° north, to Button’s Islands in the entrance of Hudson’s Strait, is taken from Monsieur Bellin’s chart, as is also the north coast of Norway and Lapland, including the White Sea, Gulph of Bothnia, Baltic Sea, and the east coast of Greenland.
The Gulf of Finland, from a large (MS.) chart, now engraving for the use of some private merchants.
The West India islands, from the east end of Cuba to the west end, including Jamaica and the Bahama islands, are from a chart published in London by Sayer and Bennett in 1779.
The south side of Cuba, from Point Gorda to Cape de Cruz, is laid down from Monsieur Bellin, in 1762.
The coasts of Newfoundland, and the Gulf of St. Laurence, from the surveys made by Captain Cook, and Messrs. Gilbert and Lane.
Nova Scotia, Cape Breton, Island of St. John, River St. Laurence, Canada, and New England to the River Delaware, from J. F. W. des Barres, Esq. in 1777 and 1778; and charts published in France by order of the King, in 1780, intituled, Neptune Americo-Septrentrional, &c. And from these charts also are taken the coast of Pennsylvania, New Jersey, Maryland, Virginia, North and South Carolina, Georgia, East and West Florida, as well as the interior parts of the country to the east side of Lake Ontario.
The other parts of this lake, as likewise Lakes Erie, Hurons, Michigan, and Superior, were copied from Mr. Green’s maps of America: The northern part of this last-mentioned lake is fixed from the astronomical observations made by order of the Hudson’s Bay Company, at Mishippicotton House.
The whole of Hudson’s Bay I took from a chart, compiled by Mr. Marly, from all the most authentic maps he could procure of those parts, with which I was favoured by Samuel Wegg, Esq. F. R. S. and Governor of that Company, who also politely furnished me with Mr. Hearne’s Journals, and the map of his route to the Coppermine River, which is faithfully inserted on the chart, together with the survey of Chesterfield Inlet made by Captain Christopher and Mr. Moses Norton, in 1762; and the discoveries from York Fort to Cumberland, and Hudson Houses (this last is the most western settlement belonging to the company), extending to Lake Winipeg, from the drafts of Mr. Philip Turnor, made in 1778 and 1779, corrected by astronomical observations. And from this lake, the disposition of the other lakes to the southward of it, and which communicate with it, is formed, and laid down from a map constructed by Mr. Spurrel, in the company’s service. The Albany and Moose rivers to Gloucester House, and to Lake Abitibbe and Superior, are also drawn from a map of Mr. Turnor’s, adjusted by observations for the longitudes.
The west coast of Greenland, as chiefly laid down from the observations made by Lieut. R. Pickersgill in the Lion brig in 1776, which determine the line of the coast only, as the immense quantities of ice choke up every bay and inlet on this coast, which formerly were, in the summer season, quite free and open.
