is sparsely settled with the exception of the western part, 
where there are many stations on the great railroads, the 
Colorado and Southern, the Atchison, Topeka and Santa Fe, 
and the Denver and Rio Grande. The area is 823 square 
miles. This county having been reduced from 4,723 square 
miles to its present area, by the formation of Adams and 
Denver counties and the enlargement of Washington and

to give its population or the number of cultivated acres.

ants in 1900. In 1900 the average magnetic declination 
was for the eastern part 12° 40' east, and for the western
