trunk, small crown of moderately small, curved, and forked 

 branches, and relatively dense foliage as compared with that 

 of both longleaf, and particularly, loblolly in its form of de- 

 velopment over the southern coastal plain; the characteristic 

 orange brown longitudinal bark plates are also well marked in 

 the older trees. The region, it would seem, affords an excellent 

 opportunity for someone to look for a farther extension of the 

 western limit of this interesting and very valuable commercial 

 yellow pine.

Qager's Fundamentals of Botany and Laboratory Guide* 



These two books represent an unusually comprehensive and 

 serious attempt to present the study of plant life so that college 

 students may secure a good perspective of botanical science as 

 a whole. Furthermore both books show clearly that the author 

 sees no place for college botany which is not founded upon ex- 

 tensive and intensive first-hand study of plants. The intent is 

 not to have students merely read interesting text materials about 

 plants, but text and manual are both so organized as to be useful 

 only in connection with constant study of plants themselves. 



In the organization of the text, presentation of functions of 

 plants precede presentation of any large amount of structure, 

 an order of presentation which has found place in the practices 

 of the best teachers of college botany, and an order which is essen- 

 tial if the student is to know "what it is all about." The text's 

 general consideration of plant functions (pages 21-143) gives 

 significance to the life-history studies (pages 144-445). Classi- 

 fication of seed-bearing plants (pages 446-501) presents the 

 modern conceptions of the relationships of the leading divisions 

 of the angiosperms, and the rest of the text (pages 502-620) deals 

 with such specially important topics as "Evolution," "Darwin- 

 ism," "Experimental Evolution," "Heredity," "Paleobotany," 

 etc.
