What an Inch of Rain Is.

An inch of rain strikes one as very little. But it is really a big rainfall. When an inch of rain has fallen it means, literally, that the amount of water descending from the sky in that! particular shower would cover the surrounding territory to a depth of one inch, providing, of course, that it did not run away or soak into .the ground, it means that on one acre water enough to (ill more than 600 barrels of 45 gallons each has fallen. This quantity of -Water weighs more than 110 tons. If the rain storm covered a territory comprising a thousand acres, which would be a very small shower, 110,000 tons of water Would fall from the clouds. Rain storms frequently cover enormous areas, and often four and five inches of water fall in one rain. In this case the total number of tons of water falling to earth is colossal.
