ably; in Mexico twenty-five is the average, whilst 
in East Africa double that number is obtained. The 
estimated yield under good conditions is from 1,000 
to 1,200 lbs. of dry fibre per acre; one ton of raw 
leaf will produce between 60 and 80 lbs. of dry fibre. 
The duration of life of the plant is determined by 
the production of the pole or inflorescence, the 
average length of life in Malaya being about eight 
years. This is a much shorter period than is the 
ease in Mexico and is chiefly due to the local climatic 
conditions. It is stated, however, that this is no 
disadvantage as the same total crop is produced in 
a relatively shorter time. 
In view of the fact that the raw leaf only produces 
from three to four per cent, of dry fibre, the cost 
of transport to a central factory would be prohibi- 
tive; it is therefore necessary to install machinery 
in the locality of the plantation. At least 1,000 
acres should be planted to warrant the erection of 
a factory installation of the necessary machinery 
for the production of first quality fibre. 
Preparation The leaves should be treated in special 
of Fibre. decorticating machines within 24 hours 
of cutting. A woman is said to be 
able to cut 600 leaves per day and a man 800. 
A “ Corona ” decorticator is said to treat 100,000 
to 150,000 leaves per day producing two to two 
and a half tons of fibre per 8-10 hours' day. The 
decorticated fibre is hung on poles to dry in the 
sun for two days, and is brushed in special brushing 
machines to remove any extraneous matter, pulp 
etc. A constant supply of good water is essential
