A rain gauge should be kept in every school yard, so that every shower can be measured.
The rain gauge consists essentially of a funnel to collect the rain, and a graduated glass to measure it.
Benedetto Castelli, being interested in the effect of rainfall on the level of a lake, constructed a rain gauge about 1628.
The rain gauge is graduated to the thousandth part of an inch, and the receiver of it is elevated 40 feet from the ground.

Each sequoia, on the other hand, draws its moisture from an area thousands of times as large as a rain gauge.
Hence they represent the summation of the rainfall over an area millions of times as large as that of a rain gauge.
