labor, maps of four have been completed, and it is hoped to 
acu the remaining three this year. 
r. F. V. Hayden’s corps will be engaged in Idaho and Montana. 
The. area to be surveyed includes the Yellowstone National Park 
and the country lying to the south and south-east about the head 
of the Green, Snake, and Mud rivers. This will be an extension 
of the work of last year. Within this area is what is regarded as 
the true apex of the continent, its three greatest rivers, the 
_ Missouri, the Columbia and the Colorado rising in a peak in the | 
northern end of the Mud River range. Lieutenant Wheeler’s 
corps will be divided into three sections known as the Colorado, 
_ Utah and California sections. 
_ The Colorado section will carry on its work chiefly in New
