The bill organizing the new Territories, having been signed by the President, in creases the number of the Territories of the United States to seven, including the previously existing ones of Washington, Nebraska, Utah and New Mexico. We subjoin a description of the new Territo ries Cotoaano includes parts of Kansas, Nebras ka and Eastern Utah. Its boundaries run as follows :—Beginning at a point where the 102 d degree of west longitude from Greenwich cross es the 87th, parallel of north latitude, thence north along said 102 d parallel to where it, in tersects the 41st degree - pf ,ttort,l3 ) . latitude, thence wrest along slid line -to the 109tli degree of westlongitade, thence south along said line to the 37th degree of north latitude, thence east along the 37th degree of north latitude, to the place of beginning. The Territory contains about 100,000 square miles, and at this time a population of. some 25,000 persons. The I,ioCky Mountains divide the Territory into two_ parte, westward flowing from, them a large number of rivers, tributary to the Colorado, and eastward others, equally. numerous and large, tributary to the Arkansas and South Fork Platte rivers. It includes the famous mining region, Pike's Peak, Hata in. gold and, other metals, cut off by deserts from the more fertile Western States, destined to be the home of advancing civiliza tion, and t give up its treasures to the sum • mons of enlightened toil. Navana is t aken from Western Utah and Cal ifornia.

That portion of the Territory within the present lithits of the State of Cali fornia is , not to be included within Nevada untiltlM State of California shall assent to the same by an act irrevecable without the consent of the United States. The Territory includes the lovely Carson Valley, thememory of whose beauty lingers with the traveler in his jour ney through arid plains and over ragged moun tains, and whose wondrous fertility, even under the rudest cultivation, shows what may be ex pected there when intelligent:industry has free course. Great mineral' wealth, especially of Pi Ivor, in which Nis richer than any other part of the ,world, and unlimited capacity for the raising , of agricultural products, will combine at an,early day.to transform this ,region into, a rich and populous State. Dacorsu lies between lat. 42 deg. 30. min. and 49 min. north, and long. 90 deg. 30 min. and 103 deg. west. It is bounded on the north by British America, east by the States of Min nesota and lowa, south and west by Nebraska. • Its length from north to south is 450 miles, its average breadth is about 200 miles; and it has an area of 70,000 square miles. It was formerly. a part of the Territory of Minnesota, but wee detached when that became a State.

The Territory includes open, grassy .pains, high-rolling prairies, a,. great numberiarlakes and ponds, and very,numerons valuabfe rivers. The climate of the south is mild ; that Of the north severe, though less so than might be expected from its high latitude. The land is, well timbered and the valleys are highly productive.. Coal abounds, in some. parts and other minerals add wealth to the re gion. The. game is plentitful, and of great value for fta furs. As soon as the Southern people
