A rain-gauge is an instrument for measuring rainfall, and consists of a cylindrical vessel containing a bottle.
The end of a funnel passes into the bottle. After a down fall of rain the contents of the bottle are poured into a
graduated measure which holds ‘5 in. of rain. The cylinder is considerably taller than the funnel to prevent
snow when it falls from being blown about. In e rain gauge should be placed in an open situation, away from
buildings, etc., and at a height of a foot from the ground.
