The successful cultivation of cotton depends on a variety of circumstances, to each of which attention should be paid; amongst the foremost in importance are, attention to the climate, and to the soil. In endeavouring to introduce into one country the mode of cultivation, long known and practised with success in another, the local peculiarities of the country, as influenced by the form of the surface, the vicinity of hills, and nature of the surrounding countries, together with the consequent modifications of atmospheric phenomena produced by it, must be observed. These, in connexion with the capacity for heat, the radiating power, the rapidity of evaporation, and the structure and composition of the soil, both physical and chemical, require investigation. These points are all of vital importance, and must be studied both in detail and in connexion with each other, to obtain useful results.
