who practiced for speed, it would seem that this form of practice 

 is preferable. I believe that speed generally takes accuracy along 

 with it and that the pupil who is speediest in the manipulation of 

 figures makes the fewest mistakes.

The Best Distribution of Time for Drills. — Tables IX shows that 

 the better progress in every group of tests was in favor of the 

 pupils who were given one fifteen-minute drill once per week 

 over the pupils who were given a five-minute drill five times per 

 week. 



Fifteen minutes once per week seems much better than five 

 minutes per day for drill work. Much better results were attained; 

 there was a saving of time, not only the ten minutes difference per 

 week, but a saving of time that was lost in taking up and laying 

 aside a special drill each day; there was also a saving of energy 

 on the part of the teacher in preparing for and administering 

 one drill rather than five per week. 



The biggest difference was in reasoning. This is perhaps ex- 

 plained when we consider that not much could be done in training 

 for reasoning in drills only five minutes in length, especially when 

 each was taken partially for reasoning and partially for funda- 

 mentals.
