* Suggestion to the teacher. — This course involves the use of a good 

 bit of apparatus, but it is all comparatively simple and inexpensive; 

 and, given stock materials and a few hand tools, the pupils can make 

 much of it on the job to their own educational profit. The school 

 should provide this equipment in advance of need, so that the pupils 

 may get their insects while the getting is good. Considerable foresight 

 must be exercised for a course that runs far into the winter season. 



Much collecting of insects also is proposed, but the teacher should 

 not do it all. Why should the pupils be deprived of such stimulating 

 exercise? They will do it gladly if given the same school credit that 

 they receive for other comparable effort. It is not necessary to organize 

 many excursions for the purpose. They will do it individually, and will 

 do it better so. Incidentally they will learn in the field something of 

 the work that insects do in the world; something that the laboratory 

 can never teach. And afterward in the laboratory they will work over 

 the specimens that their own hands have gathered, with a zest and 

 personal interest that is quite unknown to the study of "pickles" and 

 slides obtained from the laboratory shelves. 



Much material is needed. Team work will provide it easily. It is 

 all common stuff, that can be found in any locality. It will have to be
