The Capitol Land Board appointed J.T. Munson to survey the Texas Panhandle land that would eventually become the legendary XIT Ranch. Surveyors of the time likely used a tool like this. Crafted by W. and L.E. Gurley, this transit was an advanced version of the compass, but with a telescope attached.
The Gurleys introduced serial numbers in 1908, with the first digits indicating the year of manufacture, and the latter digits indicating production rate. Thus, transit #9296 was the 296th Gurley instrument made in 1909. W. & L. E. Gurley was incorporated in 1900, with all the stock held by the family.
