more evidence is in. So far we are only 



asking for a clear understanding of a rather simple process for 

 obtaining, in the form of a single arithmetical weighting, the 

 possible relationship between such illusive (and often other- 

 wise immeasurable) factors as the ones listed. To find the ab- 

 solute correlation between financial success, e. g., and physical 

 capacity the investigator might first need to obtain a large 

 group of farmers whose labor incomes had been determined by 

 the usual farm management survey methods. Then arrange- 

 ments would have to be made to subject each one of these men 

 to a physical examination, the results of which would have to 

 be stated in the form of an index figure representing the com- 

 posite findings of the test or examination. Obviously, such 



procedure is well nigh impossible. 







Continuing to disregard for the present any consideration 

 of the accuracy of the ratings or the value of the relationships 

 suggested, let us describe the further steps followed in gather- 

 ing the total data. 



Form B, given below, was decided upon after repeated 

 try-outs with many groups. The data included were furnished 

 by a senior in Farm Management in one of the Middle Western 

 Agricultural Colleges. These, as well as all of the data from 

 which basic conclusions are drawn, were obtained by the writer 

 handling classes or groups of men in person at a number of 

 universities, so that the procedure was sufficiently well stand- 

 ardized as to make comparisons possible. The classes were 

 asked to follow directions "on faith" until the period was nearly 

 over so as to prevent any attempt to guess at the desires of the 

 investigator. There was no intimation of what was to come
