as in the tea kettle, and if this deposit is tested with 

 hydrochloric acid, it will be found to be a carbonate of 

 lime. On the other hand, some water is not changed 

 by boiling, in which case either calcium sulphate or 

 magnesium sulphate is present, or both may be present. 

 Water of this kind is rendered soft only by chemical 

 means. 



Hard water is more expensive for cleansing than soft 

 water, because the soap used to soften it is wasted as 

 far as cleansing is concerned. 



Plant and animal life dependent upon water. The 

 service of water to plant and animal life cannot be over- 

 estimated. Most of the food used by plants comes 

 from minerals in the soil. For these they are absolutely 

 dependent upon water, as the plant can obtain its food 

 from the soil only in solution. As water sinks within 

 the earth it dissolves from, the soil much of the food 

 materials, which are absorbed by the fine root hairs into 

 the plant. 



Water is also vitally necessary to all animal life. 

 Before food can be absorbed into the blood it must be 

 dissolved and reduced to a thin liquid. Also the broken 

 down wastes of the body must be dissolved to be 

 absorbed into the blood, and carried to the eliminating 

 organs. The system must be kept constantly flushed 

 to eliminate the waste and poisonous matters from the 

 body if one is to remain vigorous and active. 



Water applied freely within and on the exterior of 

 the body will prevent the accumulation of the waste
