§ 354. Fern Etchings. By Jonn WiLtiaAmson, author of “ Ferns 
of Kentucky,” Louisville, Ky. John P..Morton & Co., Publishers. 
The title of this handsome book does not sufficiently indicate its 
true character, as, by adopting the geographical range of Gray’s 
Manual for its basis, and accompanying his plates with concise 
descriptions, the author has really given us a valuable, and to the 
amateur collector an indispensable hand-book of the ferns—with the 
single exception of Adiantum Capillus-Veneris, the recent discovery 
of which in Virginia was known too late for insertion—in the 
Northern, Middle and Eastern States. 
The Plates are bona-fide etchings, printed directly from the 
original copper plates, and show a marked superiority over the litho- 
graphic transfers in the author’s previous work. 
The drawings are life-like and beautiful. The author has in- 
stinctively caught the very life and spirit of the ferns themselves, and 
reproduced them so naturally that they almost seem to live and grow. 
The texture of the different species is admirably expressed, that 
of Zrichomanes radicans, Dicksonia, and Aspidium Lonchitis being 
especially finely indicated. The smaller species furnish excellent 
examples of the author’s artistic ability, while some of the larger ones 
show a positive genius for representing a mere section of a huge fern 
in such a manner as to convey an accurate idea of the character of 
the whole. : 
The plates are perhaps as well printed as could be expected from 
one inexperienced in the niceties of art required for this kind of 
work, but the clear and handsome manner in which some of them 
are executed makes the careless handling which has seriously marred 
the beauty of others all the more to be regretted, and it would have 
been better if the numbers at the top could have been placed else- 
where, or left off altogether. 
The descriptions, with two or three exceptions, are those of Prof. 
Eaton, taken either from “‘Gray’s Manual” or “Ferns of North 
America,” and in that eminent author's usual clear style,
