would undertake to engrave them ; the prior engage- 

 ments of those artists were to be fulfilled before they 



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 fur- 

 nished 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 Cap- 

 tain Christopher and Mr. Moses Norton, in 1762; and the disco- 

 veries 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 south- 

 ward 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. 

 Tumor's, adjusted by observations for the longitudes. 



The west coast of Greenland, as chiefly laid down from the ob- 

 servations made by Lieut. R. Pickersgill in the Lion brig in 1776, 

 which determine the line of the coast only, as the immense quan- 

 tities of ice choke up every bay and inlet on this coast, which for- 

 merly were, in the summer season, quite free and open: 



From the mouth of the Mississippi River, including its source, 

 and the other rivers branching from it ; all the coast of New Leon 

 to Cape Rozo, and the western coast of America, from Cape Cor- 

 rienties to the Great Bay of Tecoantepec, is taken from Monsieur 

 D'Anville. 



The Gulf of California I have laid down from a German pub- 

 lication in 1773, put into my hands by Sir Joseph Banks, Bart. 

 P. R. S. ; and the western side of it is brought together from a 

 Spanish MS. chart with which A. Dalrymple, Esq. F. R. S. ob- 

 liged me.
