CREDIT FOR HOME PRACTICE IJJT AGRICULTURE. 17 



without some encouragement. Furthermore, the problems which 

 arise during the vacation weeks are often critical and the pupil needs 

 help. 



Among the different methods of providing this supervision a few 

 are named. In each case the supervisor must be capable and w illin g. 

 Perfunctory supervision soon fails to accomplish the desired end. 



1. High-school instructor of agricultiu'e employed during the 

 summer months to supervise all projects. 



2. A local committee cooperating with the county agent, the latter 

 to advise regularly and visit projects at least once during the summer. 



3. A committee of the "parent-teachers association." With 

 changing teachers this is valuable. 



4. The local club leader cooperating with the extension service of 

 the State agricultural college, with or without a local committee. 



5. Local experts in plant or animal production might well be paid 

 for a few such rounds of visits. 



6. Resident teachers sometimes qualify as supervisors. 



FARM MANAGEMENT BASIS OF SCHOOL CREDIT. 



If the exact amount of labor for growing each crop and the ratio 

 between projects could be definitely stated, this problem would be 

 greatly simplified. It happens, however, that variations in the labor 

 required for any project due to factors not entirely within control 

 would not allow the use of averages in all cases. A study of the 

 tables appended to this study (see pp. 21 to 27) will show that 

 the labor on any given project varies much in different locahties and 

 under different conditions. 



In Table 1, page 21, are shown the number of man-hours and 

 horse-hours of labor in certain farm activities in a few States. It is 

 evident that the averages often fail to apply to any one State. These 

 figures, which are taken from unfinished studies in the Ofiice of Farm 

 Management, are to be weighed by further records but are sufficient 

 for aU purposes of this bulletin. 



The succeeding tables show the variations in labor requirements 

 and tend to prove that it is difficult to apply any average figures 

 even for one State. They also suggest some of the factors that may 

 vary the labor requirements of any project in a given community. 

 The available studies are more detailed for some crops than for others 

 and there is less information which will apply to animal projects. 



The following method is suggested for any district in which there 

 are no records to use as a basis for credit. From the figures quoted 

 in the tables select those which apparently apply most nearly to the 

 given locality. Determine upon a range of variation which will be 

 allowed in giving the credit and ask the pupils to keep accurate rec- 

 ords for the labor on their projects. It would be desirable also for
