APPENDIX. 
There are many difficulties to contend with, even In civilised 
countries. In America a system of what are known as cotton 
communities ~* has been instituted with success In certain states. 
Whether such a method would be possible where cotton growing is a 
purely native industry is doubtful. Here one has to deal with small 
scattered areas belonging to a very large number of people. One has 
to deal often with a people whose knowledge of agriculture 1s strictly 
limited and whose methods of marketing are primitive. It is a 
difficulty in all countries where cotton is cultivated; and it would 
assist matters greatly if this subject could be dealt with by a strong 
committee at the Conference. 
(11) THE CONTROL OF GINNERIES WITH SPECIAL 
REFERENCE TO THE SPREAD OF DISEASE. 
(Note by Mr. H. C. Sampson of the British Empire Cotton Growing 
Corporation.—T.C.(C)Cot.7.) 
It is an accepted fact that certain diseases of cotton of both 
insect and fungoid origin are conveyed by seed, and the question 
arises as to what action, if any, can be taken to lessen the risk of 
such spread. It is obvious that the source of the seed, viz., the 
ginning factory, is the place where any action desirable should, in the 
first instance, be taken. 
The custom in those parts of Africa, where cotton is a native 
industry, is for the cotton to be purchased in grades. These are 
usually three in number, graded according to the cleanliness of the 
sample of seed cotton and amount of freedom from leaf. In Kenya 
and Tanganyika there are rules under the Cotton Ordinance which 
read that seed of each grade of cotton ginned shall be marked and 
stored separately and that no dirty cotton shall be mixed with clean 
cotton, either before or after ginning. In Tanganyika, also, all seed 
has to be stored within the ginnery buildings and the owner of such 
seed is not allowed to retain this after March 31st of any year without 
written permission. It is presumed that the enforcement of this rule 
can be checked by the ginning figures supplied to the Director of 
Agriculture from each ginning factory, as these have also to report 
what quantities of each grade of seed cotton have been purchased in 
addition to the quantity of each grade ginned. 
Beyond this there appear to be no regulations which will assist 
in checking any spread of disease. It seems that something could 
be done if the authorities had some control over the construction, 
plan, and arrangement of the ginning factory. Tanganyika has some 
rules for this purpose, but these seem to be designed from sanitary 
and fire protection points of view rather than for the protection of the 
quality of the ginned cotton and the prevention of seed mixing. The 
Indian Cotton Committee were so impressed with this aspect of the 
question that they made a specific recommendation that all ginning 
factories erected in the future should conform to a standard plan and 
in factories where roller gins are used laid down the dimension for the 
seed cotton platform, the distance between gins, and for separate 
entrances for seed cotton and exits for lint (para. 225). In this 
paragraph also (section K) it deals with the disposal of seed with 
special reference to seed infected by pink bollworm. This committee 
even went so far as to publish standard plans which they considered
