subject of this sort ought to be very encouraging to the 

 districts which we represent. 



The CHAIRMAN : I wish first of all to thank the lecturer for 

 the most interesting address written by himself and Dr. 

 Sansom. I entirely and cordially endorse almost everything he 

 has said. I am fully acquainted with the work that is being 

 done in the Federated Malay States, and have followed it for 

 many years. I wish to mention here also the name of Dr. 

 Malcolm Watson, who is well known in connection with the 

 very active measures he has persuaded the planters and the 

 Government to adopt in certain parts of the Federated Malay 

 States. I must congratulate Mr. Evans also upon the 

 thoroughness shown by his system, of which I quite approve. 

 I am afraid there is no time for me to say more on his very 

 interesting paper, although there are many points in it which 

 I would like to discuss. I want also to thank Dr. Fernando 

 for his very excellent idea that a standing Committee should 

 be formed to deal with malaria in Ceylon. He himself has 

 done much important and useful work in connection with 

 malaria in Ceylon, and if he could get such a Committee 

 formed it would doubtless be able to do a great deal of good. 

 Of course, Ceylon is a country in which very much useful work 

 of all kinds has been done in general sanitation and in the 

 sanitation of plantations, and I feel that they will get ahead 

 very soon. I. think Sir Sydney Olivier's remarks, too, have been 

 very interesting, and I wish particularly to explain a point that 

 he referred to, namely, the fact that coolies suffer from malaria 

 when they are moved off to other places. The Jamaica coolies, 

 for instance, are almost free from malaria when they are in 

 Jamaica, but when they go to Panama they are at once 

 attacked. The same thing has been observed in many other 

 places. We must remember, however, that there are three 

 different diseases included under the head of malaria, and 

 the coolies may become immune to one of the malarial 

 diseases in Jamaica, and may be attacked by another species 

 of parasite when they get to Panama. That is one explanation, 

 but there are many others. Now in thanking the lecturer 

 and all the speakers, I should like to conclude with a sug- 

 gestion, namely, that this Congress of Tropical Agriculture 

 should appoint a standing Committee to consider the whole 

 of this very important subject important to agriculture and 

 important to humanity that this Committee should consider 

 it and report its findings to the next meeting of the Congress. 

 I am not a member of the Congress, and I am not a tropical 

 agriculturist, but I believe that this course might commend 

 itself to the Organizing Committee of the Congress. There 

 is not time to discuss such a resolution, but I believe your
