The U.S. government was pleased with the bargain.

"That portion of the Sioux reservation relinquished by the annuity Sioux, by the treaty of 1858, amounts to about five hundred and fifty thousand acres for the Upper, and four hundred and five thousand for the Lower Sioux. This was decidedly the most valuable portion of these reservations, as the land is equally fertile, and there is more than double the quantity of wood upon that tract than there is upon the tract reserved. It contains some of the best agricultural land in the State of Minnesota, and is now, before the Senate has made a decision in regard to its disposition, being settled by greater rapidity than any other section of the same extent in the State."
