This map was compiled, published, and copyrighted by P. Whitty, a civil engineer and land surveyor in Houston. Whitty served as the City Engineer from 1875-1880, and again in 1886. His map shows Houston’s five wards, railroads, streetcar tracks, roundhouses, and railyards throughout downtown.

Donated to the General Land Office by Warren H. Outlaw, Jr. in memory of Warren H. Outlaw III and conserved in 2012 by friends of the Texas General Land Office.
