The data recorded .show that all the men spent a fair amount and 

 some an unusually laro-e proportion of time on their college work. 

 All spent very little time, on the average, in exercise bevond that nec-

A year's work for a man in regular standing at Harvard Univer.sity 

 consists of seldom less than four or more than six whole (i. e., lasting 

 throughout the year) courses of study. The highest grade of marks 

 given is "A," which indicates exceptionally good work. The grade 

 "B" indicates work above the average, ''C" is given for average 

 work, and the grade " D" indicates that the student has "passed," 

 but without credit. 



As shown in the preceding table, live of the men engaged in no .sj^s- 

 tematic mental work aside from that involved in their regular college 

 courses. In these instances the grades or marks received by the men 

 in their courses of study are a tolerabl}' accurate measure of their
