preparation of tobacco for use. This is the most widely cultivated plant 
of the German colonies, being grown everywhere. Only the species JV, 
Tabacum is extensively grown, NV. rustica, which is so common in some other 
tropical countries, being scarcely known. The fungus parasites which induce 
diseases of this plant are numerous, and the way in which they affect the plant 
is equally varied. At the close of this chapter is appended a bibliography of 
the most important literature upon the subject. Many readers will regret 
that a similar appendix is not to be found with the other subjects. 
The other twelve chapters of the book are not arranged with reference to 
any particular genus or group of plants, but with reference to certain eco- 
nomic products, as “ Grains and sugars,”’ ‘‘ Edible fruits and vegetables,” and 
“Eigentliche Genussmittel””— the coffee and tea group. The colonies pro- 
duce many of the spices, and the number of plants yielding fats and oils is 
no less. Indigo, gums, caoutchouc, and gutta-percha are prominent among 
the products of the colonies. Twenty plants yield textile materials or useful 
The number of medicinal plants grown is very small, and compara- 
. tle space is given to the chapter which deals with these. 
It 8 obviously the author’s intention to deal merely with that part of eco- 
artes botany which has to do with the useful plants; and those unfamiliar 
with this subject will be Surprised to find that there are so many of these.
