For the experimental trial of such races as result from the 

 Botanical Research Farm small experimental plots, totalling two or 

 three acres, will be required, and these must be repeated in each 

 recognized type tract. The number of races sufficiently promising 

 to be subjected to such tests will be relatively small for any one season. 

 Repetition is, however, an essence of the trial in order to reduce as 

 far as possible the probable error, and the area here given will allow 

 for the necessary repetitions to be made at each centre of trial. These 

 areas are too small to form a unit in themselves, and they may 

 conveniently form part of an experimental farm. 



An experimental farm will be required for each definite tract, 

 and will form the site on which will be conducted all the purely 

 agricultural experiments, including, in addition to the experimental 

 trials just alluded to, the field trials forming the third stage of develop- 

 ment. For each of these an area of some 150 acres will be required. 



Seed multiplication demands a distinct area, or seed farm, with a 

 minimum of 150 acres, giving fifty acres of cotton. Specialization is 

 here required to ensure purity. Again, one such farm is required for 

 each type tract as defined above. 



The seed derived from the seed farms is available for distribution, 

 and for this, as follows from what I have already said, no equipment 

 in the form of land is needed. 



We may now turn to the question of organization, which will 

 realize most completely the opportunities offered by the institution 

 of such farms throughout the country. 



As before, I may commence with the Botanical Section, witli its 

 staff engaged in detailed investigation leading up to the establishment 

 .of pure races, which, in the first instance, will amount to cultures 

 each totalling in the neighbourhood of some 100-200 plants. From 

 such cultures sufficient seed will be available to provide a supply for 

 the experimental trials and also to multiply up, on the research farm, 

 a seed supply of sufficient magnitude to sow one to two acres. Of those 

 races which satisfy the preliminary experimental tests there will thus 

 be sufficient seed to carry on to the seed farm, which will be fully 

 stocked in the third year. 



The Agricultural Section, with its staff, controls the experimental 

 farms, and, by conducting the experimental trials, will have early 

 opportunity to become familiar with the results of the work of the 

 Botanical Section. It will also have the opportunity of forming an 

 independent opinion of the value of the various races submitted for 

 trial. Such check is valuable, affording, as it does, criticism from a 

 different angle. The ultimate selection as to which races are to be 

 continued and which discarded will rest jointly with the botanical 

 and agricultural officers.
