their Instruction Manual.
Sipe, F. Henry, 1404 Harrison Ave, Elkins WV 26241. 304/636-2465. "A
Layman's Guide to Land Surveying", $5. This little book tells you how to shop
for a surveyor, and how to tell him what you want done. "Compass Land

good at explaining problem solving. Most is applicable to the Silva Ranger.

Other USGS publications too.

state. Ask for a free "Topographic Map Symbols" pamphlet too. Very slow.
Last chance to remind you to take careful compass readings. The precision of
your compass readings is the major factor controlling the precision of your
surveying.
