Kemembering that the actual depth of the rainfall is mag-nified 10 times, as explained above, it is plain that if we find the water10 inches deep in the measuring tube the real rainfall must havebeen only 1 inch deep; or if the water in the tube is onty one-tenthinch (or, written as a decimal, inch deep) the rainfall must havebeen only one one-hundredth inch (or, written as a decimal, ). To save observers the trouble of always thinking about the mag-nification, and to avoid possible errors in reports, the numbers onthe graduations of the measuring sticks are not actual inches, buthave all been divided by 10, and thus represent the actual , these numbers are expr
