c APPENDIX. indigenous to the country or locality; besides these, there is always the possibility of pests belonging to other parts of the globe being introduced. It is of great importance that the Agricultural Departments of these different countries should be notified of any such outbreaks, not only for administrative purposes, so that regulations to prevent the spread of such outbreaks can be enforced, but for the information of their entomologists and mycologists, whose work might be greatly assisted by any available information regarding the pests’ life histories, how the disease may be spread, meteorological and ecological conditions which favour their spread and what chances there are for such spread. Unauthorised reports of outbreaks may cause unnecessary alarm in adjoining territories, but if the Agricultural Department concerned were to issue a full report on this, which could be circulated to other countries, it might help all concerned. For example, last year the Government entomologist of a certain colony discovered the pink bollworm in an isolated district: it also occurred in the adjoining district of a neighbouring colony. From information collected by him, it was probable that this pest occurred north of that area on the native indigenous kidney cotton. It was only by chance that the Government entomologist was called to go up to this district to examine native cotton crops, when he discovered the infection. If it is true that the pest does occur to the north of this tract and that there was a danger of infection, then such information, if it had been furnished by one Government to the other, would have been of the greatest importance both from an administrative and entomological point of view. From an administrative point of view because the District Administrative officer had been doing his best to foster cotton cultivation in his district and with considerable success, when suddenly he had to tell the people that they were not allowed to grow cotton any longer: also from the point of view of movements of cotton from this area. If a full statement of the outbreak had been issued and circulated to other countries, stating what steps had been taken to prevent the possible spread of this pest elsewhere, where the area was situated, what were its boundaries and what possibility there was of its spreading by cultivation, it might quite well have allayed any alarm created by any unauthorised reports which may have been circulated. Such reports also, following on such a Conference as this, where scientific officers concerned with ‘cotton diseases have a chance to meet and confer, will undoubtedly lead to closer co-operation and collaboration in the future, esvecially if information concerning such pests is circulated as suggested in this note. (8) SEED IMPROVEMENT: METHOD OF TESTING NEW AND IMPROVED STRAINS OF COTTON IN DIFFERENT PARTS OF THE COUNTRY. (Note by Mr. H. C. Sampson of the British Empire Cotton Growing Corporation.—T.C.(C)Cot.4.) It is taken for granted that, when new and improved strains of cotton have been produced on a central station, they will have to be tested to find out how far they are suitable for different parts of the country. 216
