are many, ma)' very properly be studied in a not too detailed 

 way, especially on field trips and by growing them under cover 

 in the schoolroom, to which they lend themselves well. Until 

 the appearance of Dr. Grout's earlier book of the same title no 

 means was at hand for the guidance of those who, with little 

 technical knowledge, desired to acquaint themselves with these 

 lovely if lowly forms, the mosses. The second edition, which 

 we notice here, extends the scope of the book to include the 

 liverworts, which are on the whole less conspicuous even than 

 the mosses, but which are as easily studied in a general way. 

 The uninitiated have now a simple guide for the study of these 

 which calls for the use of a simple hand lens only. The illustra- 

 tions are very good. Certainly every teacher of nature-study 

 will find Dr. Grout's book of much help. F. E. L. 



Book of April and May Flowers. By Anna Botsford Comstock. 

 Xew York, American Book Co. 1904. Paper, 65 pages. 

 The full title of half of this book is " My own book of three 

 flowers which blossom in April," and the second half is devoted 

 to three flowers of May. It is essentially an attempt to correlate 

 nature-study, art and language, the book consisting of sugges- 

 tions for drawing and describing the flowers on blank pages 

 inserted for that purpose. The April flowers selected are hepat- 

 ica, spring beauty, and adder's tongue ; and squirrel corn, trillium 

 and jack-in-the-pulpit are the flowers for May. An accom- 

 panying book of fourteen pages gives notes and suggestions for 

 the teacher. Both pupil's and teacher's books appeal to the 

 reviewer as having many points of excellence.
