In the same way he constantly appointed committees to go into the academic classes and see that they were correlating their work with the trade work. The tendency to backslide is especially strong in an institution which, like Tuskegee, is working out original problems. It is fatally easy for the teachers in both academic and industrial classes to slip away from the correlative method, for which the institution stands, back to the traditional routine. The correlative method requires constant thought. As Mr. Washington well knew, the average person only thinks under constant prodding. Hence, the committees to do the prodding! It is so much easier to take one's problems from the textbooks than to dig them up in the shops or on the farm as to be practically irresistible unless one is being watched. Then, in the shops it requires a constant effort to work the theory in with the practice. If the instructors in the trades tended to become mere unthinking mechanics a vigilant committee was at hand to keep them true to their better lights. And if the committees themselves ever became slack, the all-seeing eye of the principal soon detected it and they in turn were "jacked up." Mr. Washington himself had a way of leisurely strolling about day or night into shop, classroom, or laboratory with a stenographer at his elbow. If he thus came upon a recitation in which no illustrative material was used, that teacher would receive within the next few hours a note such as this: _December 8, 1914._ MR. ----: After a visit to your class yesterday, I want to make this suggestion--that you get into close contact with some of the teachers here like Mrs. Jones of the Children's House, and Mrs. Ferguson, Head of the Division of Education, and Mr. Whiting of the Division of Mathematics, who understand our methods of teaching and try to learn our methods. Your work yesterday was very far from satisfactory, _not based upon a single human experience or human activity_. [Signed] BOOKER T. WASHINGTON, Principal. Three days before he had sent the following note to the head of the academic department: _Mr. Lee, Director of the Academic Department:_ I was very glad to see the wideawake class conducted by Mr. Smith this morning. His methods are certainly good. On asking questions of the individual members of the class, I found that about half of the class did not know just what was to be found out from the measurements. If Mr. Smith will go to the new Laundry Building, in case he has not done so, he will find an opportunity to teach the same lessons in connection with a real building. I hope you will make this suggestion to him. Nothing takes the place of reality wherever we can get something real. [Signed] BOOKER T. WASHINGTON, Principal.
