Report upon the determination of the astronomical co-ordinates of the primary stations at Cheyenne, Wyoming Territory, and Colorado Springs, Colorado Territory, made during the years 1872 and 1873

I [George M. Wheeler] have the honor to forward herewith a report embodying the results from the astronomical observations made at Cheyenne, Wyoming Territory, and Colorado Springs, Colorado Territory. They are typical stations for the years 1872 and 1873, although not selected because of probable errors that are a minimum. Attention is invited to the methods employed and the order of sequence in reporting the results. Uniformity of plan seems to be a matter of so great importance in the prosecution of astronomical work in the western interior that the one now in use is submitted for consideration as a step at least in this direction.
