Dirt road through aspen forest, San Juan Mountains, Colorado, USA

The San Juan Mountains are a high and rugged mountain range in the Rocky Mountains in southwestern Colorado, and is the largest mountain range in Colorado by area. The area is highly mineralized (the Colorado Mineral Belt) and figured in the gold and silver mining industry of early Colorado. Major towns, all old mining camps, include Creede, Lake City, Silverton, Ouray, and Telluride. Large scale mining has ended in the region, although independent prospectors still work claims throughout the range

Elevation of Troughtons dividing engine, 18th century, (1886)

Elevation of Troughton's dividing engine, 18th century, (1886). Until the 1770s, scales on scientific instruments had been marked out by skilled craftsmen in a process called dividing, this was partly mechanized from the 1770s when dividing engines were introduced. Originally used on small instruments, by the 1850s they were used to graduate scales on large astronomical telescopes, making hand-dividing obsolete. This particular example was completed by John Troughton, and is similar to the first successful dividing engine which was completed in about 1775 by Jesse Ramsden. Illustration from Cyclopaedia of Useful Arts, Mechanical and Chemical, Manufactures, Mining, and Engineering, by Charles Tomlinson, Volume I, (Jamess Virtue, London, 1886)
