THE AMERICAN BOTANIST 115 



l^ngland Ferns," Dodge's "PYtiis and Fern-allies of New- 

 England," Slosson's "How Ferns (irovv," Woolson's "bV-rns." 

 and Price's "Fern Collectors llandhook" all well known a 

 dozen years ago have disappeared. Indeed, the only books 

 in this class left are l^irson's "How to Know the Ferns" 

 ($2.50), Tilton's "Fern Lovers' Companion" ($3), Cliite'^ 

 "Our Ferns in their Haunts" ($3) and "Fern Collectors' 

 Guide" ($1). 



Not only has the mortality among the older books been 

 great, but few new ones have arisen to take their places. 

 Among popular handbooks, however, we still have Dana's 

 "How to know the Wildflowers" ($3), Lounsberry's "South- 

 ern W'ildflowcrs and Trees" ($5), Peterson's "How to know 

 Wild Fruits" ($2), Mathews' "Field-book of American Wild- 

 flowers" ($3.50), and Armstrong's "Western Wildflowers" 

 ($3.50). Somewhat similar in nature are Chase's "First 

 l)ook of Grasses" ($1.25), Georgia's "Manual of Weeds" 

 ($3). liidicock's "Grasses" ($2), and Dunham's "How to 

 know the Mosses" ($2.50). 



Among Manuals there is still left that standard work 

 Gray's "Manual," 7th edition ($3), though we still regret the 

 passing of Wood's "Class-book." Small's "Southern Flora" 

 ($4) is standard for the Gulf States and Coulter & Nelson's 

 "Rocky Mountain, Botany" ($2.60) for the mountain States. 

 Gray's "School and Field Botany" ($1.88) is valuable for 

 the number of cultivated plants it includes and Wood's "Bot- 

 anist and Florist" ($2) now nearly out of print is much like 

 it. Though Britton's Manual is out of print, his "Illustrated 

 Flora" in 3 volumes ($13.50) which figures all the plants of 

 eastern America is still on the market. 



Books devoted to trees and .shrubs are still plentiful.
