(Burbach.) gage are pushed into the hole to the spot to be measured, the hole being full of rinsing water. Then on pulling the gage out and reading the highest pressure thereon the deviation from the horizontal can be calculated by consider- ing the specific gravity of the rinsing fluid. This latter, of course, is essential since water is not the only fluid; in potash mines magnesium chloride liquor is used. Borehole set horizontal.
