Water drinking.
--Improper drinking of water has killed thousands. There have been instances where thirsty armies, after long marches, have come to some river, when the men would lie down on their faces and quaff an inordinate quantity of water, with these results: some died almost instantly, others became crazy, and staggered like drunken men. Avoid drinking water as much as possible while marching.
When you feel dry, rinse the mouth with water, but do not swallow it. Drink only when resting, or before the word is given to march.
Men when heated should not drink anything cold.
In a state of perspiration, ice-water only aggravates thirst.
Drink slowly; half a tumbler of water will suffice the thirstiest man in the world, if he drinks by sips.
Take from twenty-five to one hundred sips, and swallow each time — it will quench thirst better than a quart drank in the usual manner.
In fact, it is almost impossible to get down a full glass of water taken in this way.
