20. For the emphasis on the economic side of Zoology 

 the teacher should secure all obtainable publications of 

 the following: U. S. Department of Argiculture, such 

 as the Year-book, the Farmers' Bulletins, the Bulletins 

 of the Department of Animal Industry and of the Divi- 

 sion of Entomology; the Reports and Bulletins of the 

 U. S. Fish Commission; the publications of the various 

 State Biological Surveys; the reports of the State Ento- 

 mologists; Bulletins of the State Experiment Stations 

 and of the Agricultural Colleges. This is the most impor- 

 tant printed matter that can be had for this part of the 

 work and can often be had for the asking, or at most for 

 for a very nominal sum. Write your Representative in 

 Congress and your State university for a start in this, 

 and ask for a list of the printed matter open for general 

 distribution or purchase. It is often well to get several 

 copies of some of these publications in order that the 

 students may make the freest use of them.
