things, a limited amount of water can dissolve only a 

 limited amount of any one solid. Thus, unless we drink 

 a sufficient amount of water, the impurities which are 

 produced in our bodies by the wear and tear of living, or 

 those which are taken in with food, will not be carried 

 off rapidly enough. Unless we are warm we should 

 drink all the water we desire. It is best to drink slowly 

 and often, rather than rapidly and in large quantities. 



While the drinking of a large amount of water is 

 very desirable, and even necessary, yet there are other 

 common drinks which are harmful. Any drink which 

 contains alcohol, such as beer, wines, whiskey, brandy, 

 and many others, cannot fail to harm a person to some 

 extent. Alcohol is a poison, and even a small amount of 

 a poison will have some harmful effect. Some persons 

 who use drinks which contain alcohol may seem to be 

 unaffected, but they do not know how much greater 

 progress they might have made if they had left alcohol 

 alone. Alcohol should always be considered as a drug. 



Compared with alcohol, coffee and tea are not very 

 harmful to grown persons unless used to excess. Young 

 persons should not drink either coffee or tea until they 

 have completed their growth. Even grown persons 

 should be careful not to drink too much of either coffee 

 or tea. A person who uses too much of these drinks 

 becomes nervous and irritable, and his eyes are often 

 affected.
