JNiehsgan.-The North American Jour nal, of the lith, ult., contains speech of His Excellency Gov. Cass, delivered on that day at the opening of the Le- gislatiye Council of Michigan, conven- ed at Detroit. The rapidity with which this territory is settling is truly aston ishing, and the Governor anticipates the present year, larger accession of numbers b5 emigTatiolt, than iin any pre- ceding year. In stating the subjects whichought to be presented for the con sideration of the Legislature, and by it brought before the President, His Ex- cellency invites attention to an inland communication between St. Joseph's and Maumee rivers, which would in- crease the facilities of access to one of the most fertile parts of the Union, and avoid the necessity of a hazardous navigation, through the whole extent of tile great Lakes. On this subject Gov. Cass thus remarks:-ssIf From the mouth of the St. Joseph to the south ern extreme of Lake Erie, our whole border is washed by the great Lakes, and by the straights connecting them, bat there is but one obvious and signal improvement which could be made, and which, no doubt, eventually will be made; and that is, 10 unite the mouth of the St. Joseph swith our ureasterncoast, by canal or rail road, as experience

 may establish the superiority of either, across the base of the peninsula. The

 country presentsno formidable obstacle to the execution of these works. 1t is

 generally level and well watered; and the summit on each side, with he ex- certion of one small tract, is attained by gradual and imperceptlble eleva- Ltien.o
