In the new "According to Season"* Mrs. Parsons has given 

 us a book uniform with her "How to Know the Wild Flowers" 

 and "How to Know the Ferns." and worthy to rank with them 

 in popularity. The first issue was a good book, but the new one 

 is much better and makes very good reading for vacation days 

 at any time of the year. The book follows the seasons and mar- 

 ginal titles to the paragraphs render reference easy. Several 

 chapters have been added. There are thirty-two plates in color 

 by Elsie Louise Shaw. 



That ever delightful subject for investigation — the cross pol- 

 lenation of flowers by insects — has been treated in a most in- 

 teresting way by Eleanor E. Davie, in "Blossom Hosts and In-

 be the first American to give much attention to this subject, but 

 his contributions appeared in various places and are not as well 

 known as they deserve to be. All these articles have now been 

 brought together by the editor-author, who has added sufficient 

 new matter to make a complete volume. The charming draw- 

 ings, with which Gibson illustrated his articles, have also been 

 included, and the book is probably the best handbook we have 

 for studying the cross pollenation of flowers. It contains as a 

 supplement a list of nearly 250 wild-flowers with notes on their 

 methods of pollenation and the names of the insects that assist 

 in the work. 



C. G. Lloyd, the well-known mycologist of Cincinnati has 

 just issued an excellent pamphlet on the Geasters (earth-stars) 

 of North America, illustrated with eighty figures from photo- 

 graphs. This pamphlet is one of a series that is being issued, 

 and is sent free to those who make the author suitable return in 

 the shape of puff-balls, earth-stars and allied fungi. 



The editor of the Fern Bulletin has been prevailed upon to 

 issue the illustrated Key to the Genera in his "Our Ferns in their 

 Haunts" in convenient size for carrying into the field. With this
