Original copies in printed paper covers are filmed beginning with the front cover and ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a prFnted or illustrated impres- sion, and ending on the last page with a printed or illustrated impression. The last recorded frame on each microfiche shall contain the symbol —»- (meaning "CON- TINUED"), or the symbol y (meaning "END"), whichever applies. Les exemplaires originaux dont la couverture en papier est imprimde sont film6s en commenpant par le premier plat et en terminant soit par la dernidre page qui comporte une empreinte d'impression ou d'illustration, soit par le second plat, selon le cas.

Un des symboles suivants apparaitra sur la dernidre image de cheque microfiche, selon le cas: le symbols — ► signifie "A SUIVRE", le symbole V signifie "FIN". Maps, plates, charts, etc., may be filmed at different reduction ratios. Those too large to be entirely included in one exposure are filmed beginning in the upper left hand corner, left to right and top to bottom, as many frames as required.

TO be publislieJ in England, by David Tiiomi'son, a new and correct Map of tlic Conntries in North America ; situated between llie Tarallcls of^.O degrees; and (JU dei^rees of North Latiliide ; and extending in Longitude iiom tlie east side of Lake iSuperiour, and Hudson's Hay, quilc across the Continent to tiie Pacific Ocean ; lioni ))is own local knowledge ; being the result ol' 22 years employment in discovering and laying down the several Rivers, Lakes, Hills and Mountains on' this extensive tract of country ; many parts of whicii had never before been explored ; these discoveries were only finished in 1812. The whole founded on astronomical observations, the Author being an astronomer by profession. A small pan of this work has already foimd its v/ay to the public, being copies of a rough Map laid before the North West Company of Canada. Of these regions the map makers have no doubt given the best delineation they cotdd acquire ; but of what was known, so little was founded on astronomical observations ; and their being obliged to fill tip the vacant space with what information they could procure, has led them into many errours. In this Map now ofTered to the public, almost all the great llivers on the above ])art of the Conti- nent, on both sides the great Mountains are traced to tlieir sources ; the sources of the Mississipi, and several other great rivers, and the Shores of Lake yuperiour, have been examined and laid down by the Author only. The position, extent and height of the Hills and mountains have engaged much of his attention; of which iie has many Landscapes. The last six years of his discoveries were on the west side of the Mountains to the Pacific Ocean. Each Indian Nation's Territories, with their limits, and the places of the tiading settlements of the North- West Company, will be marked out. The courses and distances, ( taken when necessary to one 100 yards,) with their calculations, kc. the astronomical observations, and rough Maps on the scale of one inch to a mile, on which th(;sc Maps are founded will be open to the inspection of the curious, while the work is publishing; and it will doubtless art')rd much speculation to the scienliiic, to find many of the great Rivers of North A- merica taking their rise in a small compass, and going oil" to the diflerent Seas like Radii from a centre. To render the Map more general, and to give conueclion to all the parts, the Author will avail him- self of the Sea Coast of Hudson's Bay and the PMcilic Ocean, &c. &c. as laid down by the latest Navi- gators and Travellers ; whatever he has not pcrsuiiiil'y examined himself^ will be in a dillercnt colour, and the authority mentioned. Notliing less than an unremitted perseverance bordering on enthusiasm could have enabled him to have brought these maps to their present stale; in early life he conceived the idea of this work, and j)rovidence has given him to complete, amidst various dangers, all that one man could hope to per- form. The Map will be engraved in a neat chaste manner, combining elegance and (X-conomy, on the scale of 3 inches to one degree of Longitude, and will form cither a m•^^) or an alias at the will of the subscriber. Tlie arduous survey, on which the Author is at ))resent employed does not permit him to present tiie Public with a description of these Countries and the nations of Aborigines. This he hopes to per- form as soon as time permits. It is expected ihc geographical map will be ready for delivery to the subscribers by the latter end of the Summer of 18!^0 at the latest. These parts of North America have long been a desideratum in Geography. He also offers to the scientific public, of the same si/e as the general Map, a Chart to contain only the grand features of this part of the Continent, such as the great Mountains and Hills, the principal Rivers and extensive Lakes ; as he proposes to delineate on this Chart the position and extent of the Coal Mines ; of the various beds of dillt-'ient kinds of Stone and Rock; of the great Meadows and Forests ; the limits of the Countries on which the IJison, K\k, Red Deer, Wild Sliecp, &c. &c. are found ; the line of the old, and new portions of this ])art of the Continent ; the line of the position of the Countries, over which, is the most constant appearance and greatest brightness of the Aurora 15or- calis; and the lines that bounds their appearance to the west-ward, beyond \\hich they are not seen ; and whatever else he may deem worthy of remark : all of which could not have been delineated on the geographical Map without causing confusion.
