Total cost, about $16.50. 

 For an additional list of books see Handbook for Teachers, to accompany 

 Bergen's Foundations of Botany; Atkinson's Elementary Botany, Appendix; 

 School Review, November, 1900, page 563; Teachers' College Record, Vol. I, 

 No. 2, page 85. Every teacher should have Ganong's Teaching Botanist, Mac- 

 millan ; the chapter on Botanical Books and Their Uses contains much valuable 

 information. Kerner & Oliver's Natural History of Plants, in four volumes 

 (listed at $15.00, Holt), is excellent, and should be procured if possible. 



THE MICROSCOPE. 



In schools where but one compound microscope can be provided it is well to 

 have a fairly good one. A desirable instrument is the Bausch & Lomb BB4, 

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

 and case. Similar equipment can be secured in other standard makes, such as 

 Zeiss, Leitz, and Reichert. A B2, with one eye-piece, two-thirds and one-sixth 

 objectives, double nose-piece and case, will cost about ten dollars less. Micro- 

 scopes and some other scientific apparatus for school use can be imported duty 

 free. 



The kind and quantity of microscopical work attempted will determine the 

 amount of necessary equipment. The following is suggested : 



Y^ gross slides. 

 1 oz. cover-glasses, 3/^ inch square. 

 3 culture slides. 

 1 razor. 

 1 oil stone.

Total cost, about $6.00. 



AUXILIARY APPARATUS. 



Many other things are convenient, but not indispensable. It may be well to 

 name a few of these : 



One glass graduate, 1000 c. c, - - $ 2.15 



An aquarium (very desirable), - $2.00 to 12.50 



Two large bell jars, ... 2.60 



A Wardian case, - - - - 13.50 



Mounted slides, - - - $5.00 to 12.00
