The Acclimatization of Stock in 

 the Tropics. 



*HE largely increa.sed interest, of recent 

 [years, in tropical agriculture, is causing more 

 ^attention continually to be given to various 

 problems that have arisen in connexion with the devel- 

 opment of lands in countries near the eijuator. A matter 

 of considerable importance among these is the intmduc- 

 tion and acclimatization of useful animals in such lands, 

 especially where those animals do not exist already. 



In relation to this subject, a valuable paper* was pre- 

 sented at the First International Congress of Tropical 

 Agriculture held last year at Brussels, which gives 

 the results (if the experience of a veterinary officer in 

 the Belgian army, who has spent much time in work of 

 the kind in the Congo Free State. 



It is pointed out by this authorit)-, first of all, that 

 the chief climatic characteristics of the tropics are the 

 uniformity of the temperature and humidity of the 

 atmosphere, as well as their higher value; the uniform- 

 ity of the atmospheric pressure; and the fact that the 

 wet and dry seasons, or seasons of heat and cold, become 

 more definitely ditferentiated as one passes from the 

 equator. There are, of course, variations of a local 

 nature, due to the influence of altitude, the nature (jf 

 the soil, the neighbourhood of the sea, the prevailing 

 winds, and the rainfall system; these are, however, 

 matters for consideration in each special case. 



In regard to the introduction of stock into such 

 regions, the conditions may be broadly divided into two 

 kinds: those where thecountry has been developedalready 

 to a very great extent, as in the West Indies; and those 

 where there has been little or no development, as in the 

 larger part of Africa. In either case, the acclimatization 

 of an animal will be the gaining of that physiological 

 state in which the organism has become adapted to the 

 conditions of its new habitat. During such adaptation, 

 the equilibrium of the living conditions, and the power 

 of resistance of an animal, are upset and decreased, on 

 account of the struggle made by it against the unaccust- 

 omed circumstances during the period of acclimatiza- 

 tion. In this struggle, the two factors to consider are the 

 climate, including all the conditions produced by it, and 

 the individual animal itself In regard to the first, it has
