APPENDIX. J One of the greatest difficulties, which is experienced in arranging such tests, in countries such as those which make up East Africa, is to get people competent to grow and to pick the crops when grown. For such tests one has to depend on European agency or native agency or a combination of both. Native agency by itself is not satisfactory, except in very few exceptional cases, and even in such cases frequent inspection would be necessary. European agency apart from officers of the agricultural services, means a Government official, a missionary, or, if there are any, a settler. The ordinary Government official is often quite willing to help, but being a touring officer, it means in practice that much of the supervision has to be left to native agency. More often than not, also, the Government official’s knowledge of agricultural operations is strictly limited. In any case, it is a question of goodwill, as the supervision of such cultivation throws extra work on him. The missionary, also, is usually very similarly placed to the Government official: his know- ledge of agriculture is limited and he is frequently away from his headquarters. Some of the Catholic missions might offer better scope, as they frequently have on their staff a lay brother, who is a horticulturist if not an agriculturist, but in their case they very often depend on the results of their labours for the funds with which to run the mission and extra work such as this would have to receive remuneration. The settler is usually too busy with his own crops to be of assistance. It thus appears that, except in very occasional cases, agricultural officers must look after such cultivation. It is not clear how the District Agriculturist can do this without prejudicing his work as a touring officer. He may be able to co-operate with the District Administrative officer, but this is largely a matter of personal relationship, which may be severed at any time by leave or transfer. Further, District Agricultural officers are few and far between. In the whole of Nyasaland there are only two such, so here at any rate there is no chance of their being able to conduct more than one or two such tests at most. Where there are sufficient Agricultural officers to run agricultural stations, in addition to district work, it might be possible for those in charge of the former to run sub-stations within fairly easy reach of their headquarters. The question of testing cottons is not merely a question of growing several strains side by side and taking the yield of each plot. Such trials must be repeated several times, and each plot of each series must be harvested separately. There are many other points which have to be considered. The land has to be stumped. The previous cropping of the land has to be considered. Newly cleared land, where there has been tree growth, is apt to affect the crop adversely and usually has a tendency to make the crop run to leaf. It is thus evident that definite and permanent sub-stations for such testing work should be instituted, especially as in many places these plots will have to be protected by fencing. The size and shape of plots is also an important question. = Whether any work has as yet been done to ascertain this is not known. The committee appointed to discuss the question might also record their opinion as to what records during the growing period of the crop should be maintained. indicating (1) those they think are 317
