unimpeachable and so thoroughly trustworthy that it may in all cases 
be quoted without fear” is warned that “even in such a simple matter: 
[sic] as names of the diffsrent species uf conifers, authors disagree!” 
Verily, they do. In the first pwrt of the descriptive chipter the author- 
ities for the names used are not given, thouzh they appear in the index. 
Synonyms are given only in the index, and there only below the accepted 
name. 
A queer set of chapter headings app2ar in the descriptive part. Thus 
chapter xv is headed “forest trees;’ chapter xvi treats of “evergreen 
trees,” including only Taxus, Torreya, Podocarpus, Dacridium and “ Salis- 
bury;” while chapter xvii is entitled “ C miferz, or cone-bearing trees.” 
What have the conifers done that they m ist b> excluded from the forest 
trees, and not be allowed to associate with the evergreens? 
Of course, the descriptive part is largely a compilation, The first 
eighty pages, containing chapters on raising trees from seed, budding 
and grafting, propagating by cutting, pruning, etc., has much useful in 
formation, though little thit is new. With the author’s plea for the 
preservation of our forests and the systematic establishment of new ones 
by the state or general government we are in hearty accord, and we sil- 
cerely hope that his book may do good in interesting farmers in such 
work, as it may come to their hands. But we can not get rid of the im- 
pression that the book before us was gotten up chiefly to sell. We do not 
therefore feel, as the author avows regarding Henderson’s Evergreen’, that 
we “can confilentially recommend it.”

This, the first memoir of a series under the general title “ Bibliotheca

eo to ar the van. A publisher in this country who shoal at
