better, they may prefer to combine the two divisions of the 

 book much more intimately. 



In any event, the booli is not a laboratory guide, or a 

 book merely for recitation, but is for reading and study in 

 connection with laboratory and field-work. The intention 

 is to present a connected, readable account of some of the 

 fundamental facts of botany, and to give a certain amount 

 of information. If it performs no other s-srvice in the 

 scliools, however, its purpose will be defeated. It is entire- 

 ly too compact for any such use, for great subjects, wliieh 

 should involve a large amount of observation, are often 

 merely suggested. 



It is intended to serve as a sujjplement to three far more 

 important factors : (1) the tearluT, who must amplify and 

 suggest at every ])oint ; (3) tlie labDraiorii, which must bring 

 the pupil face to face with plants and their structures ; 

 (o)/7e/f/-?(VAr/', which must relate the facts observed in the 

 lal)oratory to their actual pdace in Xatnre, and must bring 

 new facts to notice which can ))e oliserved nowhere else. 

 Taking the results obtained from these three factors, the 

 l)ook seeks to organize them, and to suggest exjilanations. 

 It seeks to do this in two ways: (1) l)y means of the text, 

 which is intended to he clear and untechnical, but compact; 

 ("2) by means of the illustrations, which must be studied as 

 carefully as the text, as they arc only seeoiid in importance 

 to the actual material. Especially is this true in reference 

 to the landscapes, many of which can not l)e made a part of 

 exi)erience.
