encouragement in order to replace the short (native) kinds of Gos- 
sypium indicum, as their product is superior both in quality as well 
as quantity, to that of the last named. 
If we bring TEYSMANN’S classification in accordance with the 
latest views, that is the 5 principal kinds, G. barbadense. L. (Sea- 
island cotton); G. peruvianum. Cav. {G. religiosuni ) ; G. hirsutum. 
L. (Upland cotton); G. herbaceum. L., (G. indicum. L.) and G. arbo- 
reum. L. (tree-like cotton) then that which TEYSMANN calls G. 
religiosuni must be G. hirsuium , and that which is described by 
him as G. vitifolium must be G. peruvianum. 
Whether the native kinds of cotton can be replaced by those 
which offer planters better advantages is a question which we may 
well ask ourselves. 
It is not sufficiently satisfactory from an economical point of 
view to satisfy ourselves as to the similarity of the conditions of 
growth with those of the lanek from which the cotton is imported, 
(t is true that it is a prominent factor, but the others, capital, 
labour, transport etc., are of equal if not greater importance, to 
the production as the growth conditions which are unsuitable can 
be modified if they are not favourable. 
The special remarks concerning this we will postpone at present, 
but later on will find an opportunity to view this point closer. 
Conditions of Growth. 
The cotton plant requires an atmosphere containing a Jot of 
moisture. It likes chiefly sunshine during the day and dew at 
night. Heavy rainfalls are harmful to it, both in the first, and in 
the last growing stages. If they happen to fall in the harvest time, 
they may do great damage. 
Occasional mild showers followed by sunshine are good from 
the beginning to the blossom time. A want of rain can be re- 
medied by artificial irrigation. If this is not possible then the 
rainfall in the first 3 months must amount to at least 7 5 ni * m ; P er 
month. Later on the dew may be able to completely replace this. 
A proof that the cotton "and this is especially the case of the 
finer varieties, grows best in tropical countries with a medium 
rainfall may be seen from the rainfall tables of the cotton growing 
countries in America which are given below : —
