*The total population of the United States in 1860 may be set down, in round numbers, at thirty-one and a half millions. In 1865 it is estimated that the population was thirty-five and a half millions, including the inhabitants of the Territories, estimated at 360,000 persons on January 1, 1865. In 1870, according to existing ratios, the population of this country will be over forty-two and a quarter millions.

The areas of those States marked with a star are derived from geographical authorities, the public surveys not having been completely extended over them.

The present area of Nevada is 81,539 square miles. Should the portion of Utah be detached and also that of Arizona, as above suggested, there will be added 30,550 square miles, thereby making the area of Nevada 112,087 square miles.

§ White persons.

Indians.

The present area of Utah is 106,382 square miles. By act of Congress of May 5, 1866, this area is liable to be lessened by detaching a portion on the west side of Utah to the extent of one degree of longitude, equal to 18,325 square miles, to be added to Nevada, on the latter consenting by act of Legislature. Should such act be passed, the area of Utah'will be 88,057 square miles.

**By said act of May 5, 1866, Arizona, which now contains 126,141 square miles, is proposed to be reduced, by detaching from the northwestern part a tract equal to 12,225 square miles, to be added to Nevada, the Legislature of that State consenting. The effect, in that event, will be to reduce the area of Arizona to 113,916 square miles.

Tabular statement showing the number of acres of public lands surveyed in the following land States and Territories up to June 30, 1865, during the last fiscal year, and the total of the public lands surveyed up to June 30, 1866, and also the total area of the public domain remaining unsurveyed within the same.

*The State of Nevada was enlarged by adding one degree of longitude-detached from the west part of Utah-11,728,845 acres; also by the addition of that portion of Arizona lying between the 37th degree of north latitude and Colorado river on the south, and the 37th degree of longitude west, to the eastern boundary of California, amounting to 7,823,936 acres, which will increase the area of Nevada to 71,737,741 acres. This is, however, subjeet to the approval of the legislature of Nevada, of which this office has not been advised at the date of this report. Per act of May 5, 1866.

A strip of one degree of longitude being taken from Utah on the west, for the purpose of adding to Nevada, equivalent to 11,728,845 acres, the area of Utah thus diminished will be 56,355,635 acres. Vacated Indian reservations in Utah (77,225 acres) were surveyed during the fiscal year ending June 30, 1866, but as this area forms part of that formerly surveyed as the public lands, and is included in 2,425,239, the area is not repeated.

The area of Arizona being diminished by the cutting off the northwest corner and adding to Nevada, amounting to 7,823,936 acres, its area will be 72,906,304 acres.
