This image does not appear to be what the title describes which is “Construction of Cabin Johns’s Bridge, Conduit Road, 7 miles from Georgetown. Aqueduct bringing water to Washington from Great Falls.” If you look at images of this bridge online, this does not resemble it. I believe this is the Niagara Suspension Bridge.
This image has nothing to do with the title on verso which is “Base of Washington Monument, 555 ft. high, 298 steps, 55 ft. square at the base. Cornerstone laid in 1848. By 1855 the shaft had attained the height of 152 ft. Money was exhausted not to be resumed until 1878 where Congress appropriated money for its completion. Finished monument was dedicated Feb. 21, 1885.” I believe this is the Niagara Suspension Bridge.
