less of the class of students concerned, the chief object of 

 botanical instruction in an elemntary course should be to 

 teach the fundamental facts and principles of botany and to 

 relate these to problems of practical interest. 



A list of the chapter headings will suggest the nature of 

 the topics treated: {lutrodiiction) the nature and subdivisions 

 of botany; a general view of plants; {Part I) flowers; pistils 

 and stamens ; seeds and fruits ; germination of seeds, seed- 

 lings ; cells and tissues; roots; stems; buds (including growth of 

 stems, pruning, propagation by stems); leaves; (Part II) thal- 

 lophytes (separate chapters on algae, myxomycetes and bac- 

 teria, fungi); bryophytes ; pteridophytes ; spermatophytes 

 (two chapters) ; classification of angiosperms, and families of 

 economic importance ; ecological classification of plants ; varia- 

 tion ; heredity ; evolution. 



The present edition dift'ers from the first in that several por- 

 tions of the text have been rewritten, the chapter on variation 

 added, and many of the illustrations replaced by new or im- 

 proved ones.

The second edition, completely rewritten, of Chas. C. 

 Beam's Trees of Indiana * is an extraordinarily satisfactory pub- 

 lication. It is gratifying to consider that thousands of students, 

 farmers, amateur botanists, and tree-lovers in general throughout 

 that state may profit by such carefully written work from the 

 pen of Indiana's most thorough student of the local flora. 



Deam has recognized 132 species and 20 varieties of forms. 

 Each of the former and one of the latter is illustrated by a full- 

 page half-tone plate, photographed from a herbarium sheet. 

 Since the sheets were chosen from Beam's own carefully pre- 

 pared herbarium, the results are excellent and in most cases 

 far better than one would naturally expect. Either fruits or 

 flowers, or both, and frequently bark, are represented. The
