in Senegal as 2,000 kilogrammes per hectare, 7.¢., 1,780 Ibs. per 
acre. In his experiments in South France, mentioned earlier, 
M. Chaise obtained the large yield of 2,200 kilogrammes per 
hectare or about 1,960 Ibs. (Heuzé, op. cit., p. 139). 
xperiments have been tried in Florida with this plant on 
irrigated land, but the yield is not known to us. 
One thing is very evident, that the size of the crop depends 
largely upon intelligent cultivation. 
The yield of haulms per acre is given by Subba Rao (Le., 
p- 275) as 1 ton per acre, by Handy for the United States as 1-2 
tons peracre. — 
CONCLUDING REMARKS. 
We have followed the history of Arachis hypogea from its 
discovery by the early colonists of the New World to the present 
frica t 
the Portuguese, who traded on the Guinea Coast ; we have noted 
its early and obscure history in Asia, and have seen how widely it 
is now acclimatised, and what a great part of the world is capable 
of producing crops of it; even in Central Europe this is possible. 
Then, when the scarcity of olive oil demanded a substitute, 
France holding the chief trade in oil-seeds not only came forward 
as the market for ground-nuts, but her settlements obtained the 
export trade, and Gambia, Senegal, Pondicherry, and in a measure 
At first West Africa supplied Europe, then nuts came from India, 
and even China and the Argentine, and now in addition there is- 
an increasing importation from the Mozambique coast ; the latter
