279—Repairing Figures and Divisions.—Surveyors going abroad will find it very convenient to have a few tubes of artist's oil colours—white, black, and vermilion, with one or two sable brushes to touch up any divisions or figures upon the staves that have become accidentally injured or worn off by friction. A tube of medium is also useful, which will cause the colour to dry quickly and leave it bright. The tubes of colour will keep any number of years if the caps are carefully replaced. The brushes after use should be well washed with soap and hot water, rubbing the soap in quite thickly till they are quite clean, and then well rinsed before putting them by.

280.—Iron Triangle.—For use of the staff in the field, particularly in open grass or moist lands, a triangular plate of iron, as represented Fig. 108, is very useful. This is trodden down firmly by the staff holder before he places the staff upon it. In use it gives a certain base to turn the staff upon from fore to back sight. It is very inexpensive.
