APPENDIX. 315 
With regard to the former, the situation would be very much 
cleared if suitable arrangements could be made to put into effect the 
suggestions put forward in T.C.(C)Cot. 3. At the present time 
information about the presence and distribution of insect aud 
fungoid pests is so scanty that the several countries have to protect 
themselves by enforcing stringent regulations to prevent the possible 
introduction of unknown pests. This action may seriously hinder 
fhe development of the cotton industry in many parts of East Africa, 
where the natural outlet for inland transport passes through territory 
controlled by another Administration. The boundaries between 
these different Administrations are often purely artificial and may 
run through the centre of a well-defined cotton tract where the same 
variety of cotton is grown and the same pests occur. 
Another question which appears to need attention is the 
necessity of obtaining information as to what pests, whether insect 
or fungoid, can be carried in seed, seed cotton, or lint. It is possible 
that sufficient is known of the life histories of many such pests to be 
able to state deflnitely in what cases such danger exists. 
The question of keeping seed stocks pure is ome which needs 
consideration in the event of cotton being allowed to pass from one 
territory to another, as is frequently the case when tentative 
cultivation is started and there are no means of ginning the crop 
without transporting it elsewhere. This seems to imply that there 
should be closer co-operation between the Agricultural Departments 
of different administrations. If it is intended to attempt cotton 
cultivation in an area where the cotton harvested must be transported 
through another territory before finally being baled for export, then it 
seems clear that the variety of cotton used for such tentative 
cultivation should be the same as that grown in the country where 
it is to be handled. This would obviate any danger of contaminating 
the seed supply with seed of other varieties. 
There is one aspect of the question which seems to need 
examination. In reports on cotton growing in some of these countries 
the seed from certain tracts has been condemned for sowing because 
the area where this has been grown does not produce the same length 
of staple as is produced in other tracts or climate where the same 
seed is used. This means that the soil in which the cotton is grown 
influences the quality and length of the staple. It does not, however, 
prove that the variety has deteriorated, and it seems that this is a 
matter for experiment. The experience of the writer of this note is 
that if such seed is again used in soils which are known to produce 
stanle of good quality no deterioration is evident. 
(7) NOTIFICATION REGARDING THE DISTRIBUTION, 
EXISTENCE AND OCCURRENCE OF INSECT AND 
FUNGOID PESTS. 
{Note by Mr. H. C. Sampson of the British Empire Cotton Growing 
Corporation.—T.C.(C)Cot.3.) 
At the present time there appears to be very little co-ordination 
between the different countries comprising East and South Africa in 
the matter of giving information regarding insect and fungoid diseases 
and a perusal of the various annual reports of the different countries 
shows that these do not give such information in sufficient detail. 
In a new cotton country, such as East and South Africa is, 
there are possibly many pests which attack cotton, which are
