enumeration there is an index to the families, and in addition a 
large and very interesting map of Upper Guinea, showing the 
routes followed by the author, the character of the vegetation, 
and the geographical range of the more important economic 
plants, which include among others, the rubber producing species 
of Apocynaceae, the Oil and other palms, the Shea-utter tree, 
and Gum-arabic. 
Dr. Chevalier is to be warmly congratulated on this contri- 
bution to our knowledge of the vegetation of “ Upper Guinea,” 
which, together with the numerous collections we already possess 
from our own West African Colonies, would provide abundant 
material for a critical and more comprehensive study of the 
whole of this part of Tropical Africa. J. H, 
The Book of the Mango.*—This work contains chapters on the 
History, Propagation, Planting, Culture, Marketing, Transport 
of Trees, Scions and Seeds, Renovation of neglected plantations, 
Flowering and Pollination, Pests and Diseases, Uses and Canning 
and Classification of the Mango. In the earlier chapters, 
especially on history and propagation, Woodrow, Firminger, 
Watt and Maries in India, Wester (Phillipines), Popenoe (Cuba), 
Collins (Porto Rico), Macmillan (Ceylon), Higgins (Hawaii), and 
other well-known writers on the subject have been quoted; but 
the greater part of the work is, as stated in the preface, the 
results of original observations and experiments made since 
1908 in the Ganeshkhind Botanical Gardens, Kirkee, and in 
_ various parts of the Bombay Presidency. This Presidency, from 
its more favourable situation, seems to have taken a prominent 
part in popularising the fruit in the markets of this country. 
Fruits have come into Covent Garden from India and Jamaica 
at odd times, and only recently, in the ‘Times Weekly ” of 
May 20th last, an examination at Covent Garden Market is 
illustrated of a consignment of ‘‘ Alphonse ”’ Mangoes, which 
had just reached London from Bombay (by the use of speci 
packing cases) in good condition, Experiments have been made 
in sending fruits from the Ganeshkhind Gardens to Marseilles, 
Trieste and London by Mail Steamer (not in cold storage), and 
the authors express the opinion that, unless fruit can be sent in 
large quantity and in cold storage, there is no likelihood of 
developing an overseas trade; they were, however, more hopeful 
that a trade in canned mangoes may be developed, and apparatus
