al APPENDIX, 
all future factories to be erected should adopt. No definite 
regulations other than this were made about the disposal of seed, but 
this is hardly necessary under Indian conditions, where the seed will 
always find a ready sale as cattle food. In Africa, however, the 
matter is different. In many parts of the country the seed has no 
commercial value; some of it is certainly used for engine fuel to run 
the factory with, but the rest as often as not is left out in a heap in 
the open to rot. In Africa also, the saw gin is frequently installed 
and, unless the condenser is cleaned out thoroughly before ginning 
another grade of cotton, there is bound to be considerable mixing of 
seed with the next grade to be ginned. 
It appears that this is an aspect of ginning which might be 
investigated to see what steps can be taken to ensure that the quality 
of seed for sowing is the best procurable, and that all factory 
precautions can be taken to prevent the spread of disease. 
(12) TEMPORARY EXCHANGE OF TECHNICAL SPECIALISTS 
BETWEEN DEPENDENCIES. 
(Paper by the Director of Agriculture, Tanganyika Territory. 
. —T.C.(C)Cot.11.) 
The purpose of this would be to make the widest possible use of 
the knowledge and experience of the different specialists and in turn 
to increase their own knowledge and experience under the larger 
variety of conditions that would be made available to them. 
It is manifest that cotton investigations and cotton specialists 
would benefit by such a scheme. It should be a matter for interesting 
discussion as to whether it would be of important benefit to other 
technical agricultural officers such as agricultural economists and 
chemists, and myecologists and entomologists. 
In any case it would be a necessary part of the scheme to ensure 
that such temporary exchange would not interfere with the continuity 
of the work and investigations of outgoing officers. The latter would 
be responsible for informing incoming officers fully of the details, 
purposes and intended development of their work, and these would 
be strictly responsible in an even greater degree for ensuring (as far 
as humanly possible) that no interference or interruption occurred in 
regard to that work. 
Administrative arrangeinents and control for such a scheme 
would be simple. What is not as simple is the making of a plan to 
ensure that all participating dependencies obtained a fair share of 
the exchange, and that the scheme was not followed desultorily or 
was likely eventually to fall through. The formulation of such a 
plan is a matter for discussion. It is suggested as a basis that the 
scope of the duties of a technical officer should for the purpose include 
the obligation to spend a definite proportion (interrupted or not 
interrupted ?) of each period of two consecutive tours (or period of four 
years) on exchange, and that each Director of Agriculture in the 
countries participating in the scheme should be made responsible for 
advising his Government in good time when the exchange period of 
an officer was due. 
Not the least useful part of the work of those delegates at 
agricultural conferences occupying administrative posts would be to 
devise a working basis for the exchanges required in the period to
