Surveyor's Transit
name: label: maker
content: Young, William J.
notes: label: Description
content: This surveyor's transit marked "Wm. J. Young Maker" and "3192" and "Philadelphia" was made in the early 1850s, soon after William J. Young began putting serial numbers on his instruments. The horizontal circle is larger than the compass box, silvered, and graduated every 30 minutes of arc. The two opposite verniers are on a beveled edge; one reads to single minutes, and the other reads to 1/100 of a degree. The tangent screw that moves the plates is at the south side of the horizontal plate. Level vials are at north and west.
