106 NOTES ON THE NORTHWEST. 



of 1833, and the establishment of the territorial government 

 in 1838, the Black Hawk Purchase had gathered a white 

 population of 22,000. In 1840, at the taking of the census, 

 in June, it contained 43,000. It is supposed that the usual 

 annual increase by emigration since that time has been about 

 the same, or something near ten thousand yearly ; and, with 

 a sufficient allowance for an augmented natural increase, in 

 proportion to the greatly augmented basis, the whole yearly 

 addition to the population cannot be less than 12,000, or, for 

 the six years, to June, 1846, 72,000 ; which, added to the 

 43,000, makes the whole 115,000. This is believed to be 

 under the true amount, as, in 1843, and the spring of 1846, 

 an unusual impulse was given to emigration by the acquisi- 

 tion of new territory, and the allowance for natural increase 

 is made very small. It is more probable that the whole 

 actual population at this time (July 4, 1846) is 150,000. 



Wisconsin, as constituted by the division into two terri- 

 tories, had, at that time, July, 1838, 21,000 inhabitants. By 

 the census of 1840, it had 34,000. Its increase in the two 

 intermediate years had been much less than that of Iowa, but 

 in some subsequent periods it has been very great; and it 

 contains, by a recent census, about 160,000. The least total 

 amount that can be assigned to the two territories is little 

 more than 300,000, at this time. 



Acts have passed Congress, in June and August, 1846, for 

 admitting both territories into tlie Union with the attributes 

 of sovereignty. They will probably be adopted by the peo- 

 ple ; and, in the present year, two new and bright stars will 

 be added to the Union. 



At the moment that Congress was acting upon the admis- 

 sion of Iowa and Wisconsin into the Union, a treaty was in 

 progress, and is now completed, by wliich the Potawatamis 

 have ceded their lands lying east of the Missisippi, Missouri,
