For the sake of conciseness and convenience of reference I will first distinguish the various natural divisions of the country.1.The Assiniboine Valley, or first prairie steppe.This includes all of Manitoba south and west of a line drawn from Pembina Mountain north, just west of Portage la Prairie, and thence northwest to Fort Pelly.This line is also the eastern edge of the cretaceous formation.The district is essentially a prairie region, the only wooded tracts of any extent being the flat tops of the elevated table lands, known as Pembina, Turtle, Riding, and Duck Mountains.'The first two are at the United States Boundary.The others are on the northeast edge of this region.Carberry is just north of the Assiniboine River, about the center of the region.The Big Plain is an unusually flat prairie, between Carberry and the Riding Mountain.The Big Swamp is a spruce and tamarac swamp, between Carberry and the river.Moose Mountain is just outside and west of Manitoba, at the head of the Souris River.Qu'Appelle is on the Qu'Appelle River, outside and west of Manitoba, one hundred miles up the river from its junction with the Assiniboine.The observations for the region are my own, as I have visited nearly every part of it. I have, however, received much valuable SETON on the Birds of Western Manttoba.| April assistance from Mr. G. F. Guernsey, who is responsible for the records from Qu'Appelle. 2. The Red River Valley.This includes the country east of the first region, south of the large lakes, west of the 96th meridian, and north of the United States Boundary.This also is a prairie region, but of lower level than the preceding and characterized by extensive tracts of marsh.It is partially wooded in the southwest.Geologically it is chiefly Silurian on the east side of the river, and Devonian on the west.Long Lake isa long, marshy body of water lying just west of Winnipeg.Shoal Lake is an extensive marshy lake near the southeast end of Lake Manitoba.Although I have visited this region myself, my notes are chiefly from information supplied by Mr. Wim.L.
