48 NATURAL RESOURCES OF HOME ENVIRONMENT 



when General Allenby's army marched across the desert 

 into Palestine, the British engineers built a pipe line 

 which actually did carry water from the Nile under the 

 Suez Canal and supplied the army in the desert with 

 fresh, pure water, so the saying of the Turks was carried 

 out almost as if it had been a prophecy. 



No one would think of building a house or locating where 

 there is no supply of water, and modern science has 



shown that pure 

 water is one of the 

 greatest factors in 

 good health. Be- 

 sides using water at 

 home for washing, 

 and sprinkling the 

 lawn, we use it in 

 the form of ice and 

 as steam or hot 

 water to heat our 

 houses, to turn mo- 

 tors which generate 

 power and save la- 

 bor, and in many 

 other ways of which 

 you can think. Why not try to find out how many ways 

 water can be used by man in the home? This would 

 make an excellent home project. But in addition to these 

 uses, the human body needs water, first because a very 

 large percentage of it, about 65 per cent, is made up of 

 water. Furthermore, in order that foods may become part 

 of the body they must first be dissolved in water and soak 

 through the walls of the food tube to become part of the 



Cells are the units of building material in the human 

 body as bricks are of the house.
