described no less than 630 trees; and about 600 fine illustrations, 
the work of Mr Charles E. Faxon, the artist who was responsible 
for the magnificent drawings of the Szlva, are interspersed 
throughout the text. 
In the Szlva Professor Sargent followed the systematic order 
adopted by English authors, but in the JZanual he has 
reversed this order, and has adopted the arrangement of Engler 
and Prantl’s Die Natiirlichen Pflanzenfamilien, beginning with 
the Gymnosperme (Conifere and Taxacez) and finishing with 
the Gamopetalous Dicotyledonous <Axgiosperme (Ericaceze to 
Caprifoliacez), Such an arrangement is unfamiliar to those 
accustomed to British works on systematic botany, and we 
confess we should have preferred the arrangement of the 
Silva, although some such arrangement as that of Engler and 
Prantl, being more in accordance with modern ideas, will no 
doubt ultimately be adopted. The nomenclature adopted in 
the Manual is that of the Silva, and as this was freely criticised 
when that work appeared, it will be unnecessary to refer to it 
here in any large measure. But as Professor Sargent has not 
given the synonyms in the Janual, English readers will have 
difficulty with some of the names. For example, the Douglas 
fir occurs as “ Pseudotsuga mucronata, Sudw.—Douglas Spruce, 
Red Fir.” Of course “Douglas Spruce” leads one at once to 
the plant the author refers to, but Pseudotsuga Douglasit and 
Douglas fir, the technical and the common names respectively 
which we have adopted for the tree in this country, nowhere 
occur in the book. To take another example, the tree 
commonly known in Britain as Prince Albert’s fir, which 
is generally placed in British works either under TZsuga 
Mertensiana (Carr.), as in the Kew Hand-list of Contfere 
(2nd ed.), or Z. Albertiana (Kent), as in Veitch’s Manual of 
the Conifere (2nd ed.), occurs in the J/anual under “Tsuga 
heterophylla, Sarg.—Hemlock,” with no reference whatever to 
any of its synonyms, or to any common name but “ Hemlock”; 
while Zsuga Mertensiana (of Sargent, not of Carriere) is the name 
applied, as is the case in Veitch’s Manual, to the “‘ Patton spruce” 
(Z. Pattoniana, Engelm., in the Kew fand-list). This mixing 
up of names is very puzzling, but it is rendered much more so 
when, as is the case in this JZanwa/, no synonyms are given. 
It is difficult to understand, too, how Ades Lowiana (of 
Murray), which is recognised by British authorities either as
