bundles may be placed in the locker with which every student should be 

 provided. This desk will, by having classes in sections, accommodate 

 two students. 



6. A large amount of the essential study of grasses and forage crops may 

 be accomplished without any microscopic equipment. The important require- 

 ment for lenses for this work is a rather large field. If each student is 



provided with a one-inch 

 focus lens, the other re- 

 quirements may be met 

 by a few lenses or micro- 

 scopes placed upon side 

 tables where students 

 may use them as needed. 

 The following are sug- 

 gested as useful: (1) 

 reading glass and stand 

 consisting of lens 4 

 inches in diameter with a 

 focus of 9 inches; (2) 

 dissecting microscope with 

 one and a half and three- 

 fourth-inch lenses (such 

 as Bausch & Lomb's No. 

 2); (3) a compound 

 microscope with one and 

 two-inch eyepieces and two-inch, two-thirds-inch and one-sixth-inch objectives 

 (such as Bausch & Lomb's Stand BB). Each student may be furnished with 

 the dissecting microscope just mentioned, but when this cannot be afforded, 

 a simple dissecting microscope (such as Bausch & Lomb's S3) will be 

 found useful. 



7. Students should have access to bulletins of the experiment stations, and 

 there should be at least one set of the Experiment Station Record for each 

 20 students. For list of books, see outline for discussion of grasses and 

 leguminous forage crops. (Ill) 



111. OUTLINE FOR DISCUSSION OF GRASSES AND LEGUMINOUS FORAGE CROPS. 

 The author has for a number of years required students to make an individual 

 study of specimens of forage crops and of a selected list of station publica- 

 tions, together with some of the more useful books used as reference merely. 

 Below is submitted an outline which experience has shown to work sat- 

 isfactorily. Students have been able to complete the outline on grasses in 

 six weekly practicums of two and a half hours each by writing up the notes 

 outside the practicum hours; if done separately, legumes will require about 

 an equal amount of time, but if the work follows the grasses, it may be com- 

 pleted in somewhat less time. For leguminous forage crops see 253.
