THE AMERICAN BOTANIST. 
em America" ($1.75) is older than any of the foregoing, 
but is still useful. 
After the flowering plants become well known one 
often has a desire to specialize among the lower plants. For 
a single book on ferns, select Clute's "Our Ferns in Their 
Haunts" ($2.15); for the next best Parson's ''How to 
Know the Ferns" ($1.63). Waters "Ferns" ($3.30) is also 
desirable for reference. In fern allies there is but one 
book, "Clute's Fern Allies of North America" ($2.00). All 
these are popular handbooks for naming the plants. For 
a technical book select Underwood's "Our Native Ferns" 
($1.08). In mosses, Grout's "Mosses With a Hand Lens" 
($1.75) is most desirable. Of the various txwks on mush- 
rooms, Atkinson's "Mushrooms. Edible and Poisonous" 
($3.00) and Marshall's "Mushroom Book" ($4.00) are 
aboiu e^-enly matched. r^Iarshall's book is probably best for 
the beginner. Atkinson's ]>eing the more technical. ' Roth are 
well illustrated. For a text-l>ook covering the whole field 
ot the lungi, Underwcx)d's "Moulds. Mildews and Mush- 
rov.mi-,- ( Sl.OO) may be selected. Schneider's '-Guide to the 
StiuK of Lichens" ($2.50) and Sargent's -Lichen..logv for 
Beginners" (50c) are both excellent. 
All the lx)aks thus far mentioned may be listed as so 
many heljH to becoming acquamterl with' the plants, but 
many .jf the m.>st enduring pleasures of b,tanv do not ap- 
pear until the names of the plants are knr)wn. Xot until 
one has a general knowledge of plants and plant relation- 
ships can he understand and enjoy the best literature of the 
-uKtc,-. T'len .uch Ivx^ks as Dana's "According to Season" 
- <^t's '-FlAuers and Ferns in Their Haunts" 
- "(iarae!T ..f Simples" (SLr»2) and many 
- c a new charrn. As one extends his ac- 
-- the plants mure and more of such lx)oks
