Each sequoia, on the other hand, draws its moisture from an area thousands of times as large as a rain gauge.
The rain gauge consists essentially of a funnel to collect the rain, and a graduated glass to measure it.
Hence they represent the summation of the rainfall over an area millions of times as large as that of a rain gauge.
The rain gauge is graduated to the thousandth part of an inch, and the receiver of it is elevated 40 feet from the ground.
A rain gauge should be kept in every school yard, so that every shower can be measured.
A rain gauge which was not exposed to the full intensity of the storm caught 8.80 inches of water in one hour.
Benedetto Castelli, being interested in the effect of rainfall on the level of a lake, constructed a rain gauge about 1628.
The rain gauge consists of three separate parts, the receiver A, the overflow attachment B, and the measuring tube C.
Six years ago I received from Australia an exceedingly beautiful photograph of a thin pellicle found in a rain gauge.
