XXXVIII ADMINISTKATIVE KEPOKT [eth. ann. 20 



Man produces forms of things that he may utilize air, water, 

 rocks, ])lants, and animals. He utilizes air when he produces 

 things that insure proper ventilation. A chimney is a form for 

 this purpose; an opening' in a room and a shaft in a huilding 

 are forms of this character; a fan is a form designed to secure 

 a better movement of the air. 



For the utilization of water primitive man constructs a gourd 

 into a drinking cup, or he moulds clay for the purpose of 

 holding water, or he constructs wickerwork jugs for this pur- 

 pose; so man digs wells an<i constructs reservoirs, and lays 

 ])ipes for the transportation of water, and in higher civilization 

 lie constructs filters for the purification of water. Thus 

 innumerable forms are constructed by man for the utilizatiou 

 of water. 



In the same manner many foi'ms are produced for the utili- 

 zation of rock material. The rocks are built into houses as 

 rock structures proper; the clays are molded into bricks or 

 adobes to be built into houses. Iron is extracted from the 

 rock and molded into innumerable forms for men's use. Cop- 

 per, gold, and silver are in like manner produced as sub- 

 stances and wrought into forms which serve men's purposes 

 for ^v•elfare. 



Plants are used for fuel and wrought into forms that they 

 may be utilized in stoves and furnaces. Plants are also 

 wrought into forms of lumber and used in constructing forms: 

 houses, furniture, vehicles, and ten thousand other shapes, 

 that they may be useful to man ; and many substances are 

 extracted from plants to be wrought into forms. Many resins 

 are used in this manner; indeed the forms produced from the 

 product of the rubber tree that are useful to man are too great 

 for enumeration. 



Time fails me to tell of the innumerable forms into which 

 animal substances are wrought for the use of man. But animal 

 substances and vegetal sul)stances have their grand use as 

 food. The forms into which tliey are converted before they 

 reach the entelic use are innumeral)le, but the subject is so 

 often illustrated in daily hfe that to call attention to the facr is 

 all that is necessar}- to our purpose.
