MEASURING THE RAINFALL.
The quantity of rain falling at any place is estimated by means of a. very simple piece of apparatus known as a rain-gauge. The most common form of rain-gauge consists of a copper funnel, the area of the -mouth of which is accurately known. The rain collected in this funnel flows into a graduated measure, which can very easily be constructed by anyone out of a small glass tumbler by pasting on its side a strip of paper, carefully marked off into inches, half-inches, quarters, eighths, and sixteenths, or into inches, tenth, and twentieths. Supposing that the area of the mouth of the receiving funnel is five times that of the graduated measure, then a depth of five inches in the measure would represent a depth of one. inch on an area equal to that of the aperture of the funnel.
