engrave them; the prior engagements of fhofe artifts were 
to be fulfilled before they could begin ; the labour and fkill 
to 
and Weft Florida, as well as the interior parts of the country to the Eaft fide of Lake 
Ontario. 
The other parts of this lake, as likewife Lakes Eria,' Hurons, Michigan, and Superior, 
were copied from Mr. Green’s maps of America : The Northern part of this laft-men- 
tioned lake is fixed from the aftronomical obfervations made by order of the Hudfon’s Bay 
Company, at Mifhippicotton Houfe. 
The whole of Hudfon’s Bay I took from a chart, compiled by Mr. Marley, from all the 
raoft authentic maps he could procure of thofe parts, with which I was favoured by Samuel 
Wegg, Efq; F. R. S. and Governor of that Company, who alfo politely furnifhed me with 
Mr. Hearne’s Journals, and the map of his route to the Copper-mine River, which is 
faithfully inferted on the chart, together with the furvey of Chefterfield Inlet made by Cap¬ 
tain Chriftopher and Mr. Mofes Norton, in 1762 ; and the difcoveries from York Fort 
to Cumberland, and Hudfon Houfes (this laft is the moft Wefternfettlement belonging to 
the Company), extending to Lake Winipeg, from the drafts of Mr. Philip Turner, made 
in 1778 and 1779, corrected by aftronomical obfervations. Andfrom this lake, the difpo- 
fition of the other lakes to the Southward of it, and which communicate with it, is formed, 
and laid down from a map conftructed by Mr. Spurrel, in the Company’s fervice. The 
Albany and Moofe rivers to Gloucefter Houfe, and to Lake Abbitibbe and Superior, are 
alfo drawn from a map of Mr. Tumor’s, adjufted by obfervations for the longitudes. 
The Weft coaft of Greenland, is chiefly laid down from the obfervations made by 
Lieut. R. Pickerfgill in the Lion brig in 1776, which determine the line of the coaft 
only, as the immenfe quantities of ice choak up every bay and inlet on this coaft, which, 
formerly were, in the fummer feafon, quite free and open. 
From the mouth of the Miflifippi River, including its fource, and the other rivers 
branching from it; all the coaft of New Leon to Cape Rozo, and the Weftern coaft of 
America, from Cape Corrientes to the Great Bay of Tecoantepec, is taken from Mon- 
fieur D’Anville. 
The Gulf of California I have laid down from a German publication in 1773, put into 
my hands by Sir Jofeph Banks, Bart. P. R. S.; and the Weftern fide of it is brought to¬ 
gether from a Spanifh MS. chart, with which A. Dalrymple, Efq; F. R. S. obliged me. 
The coaft of Brazil, from Sera to Cape Frio, is copied from a fmall chart of that part, 
bv Mr. Dalrymple. 
For the Southern part of Africa, from the Cape- of Good Hope to Point Natal, I have 
taken the authority of the chart of Major J. Rennels, F. R. S. (hewing the extent of the 
bank of Lagullus.
