Repair Work in Concrete. A glance at Table 9 reveals that 

 there is little repair work done in concrete. This is no doubt large- 

 ly due to the permanance of the material as well as to the fact that 

 it is not used as frequently as is wood. For purposes of agricultural 

 education, the field of construction work in concrete is more prom- 

 ising than that of repair work. 



Table 10 



Kinds of construction work in concrete, occurring 27.5 or more times per 

 1000 farms, as found on 400 Pennsylvania farms. The work done is that done 

 by expert mechanics who follow such work as a vocation.

 The above table covers 14 out of 29 kinds of work reported on. 



Work Done by Mechanics. The kinds of work mechanics per- 

 form in concrete for farmers, (Table 10) is similar to that under- 

 taken by the latter. The significant thing brought out is that farm- 

 ers do most of such w r ork themselves. The fact that equipment for 

 work with cement is inexpensive is an added reason why it should 

 not be overlooked in agricultural education. 



Work in Iron and Steel 



Much has been said for and against the practice of requiring 

 agricultural students to take forge work as a part of their secondary 

 education. In Pennsylvania, on the 400 farms studied, fourteen 

 farmers per hundred have forges on their farms and, of that four- 

 teen, thirteen do welding and tempering. (See Figure 6). The 

 following diagram, Figure 7 , sho\vs how many farmers per hundred 

 construct the twenty-one objects listed and how many repair such 

 work, but do not make it. In the latter group, the clevis, punch, 

 cold chisel and tongs are most prominent relatively.
