    7] VARIOUS CAMPAIGNS 4i There is no doubt that a great reduction in the number of mosquitos was effected by our measures; but, of course, our work was meant only for a temporary object lesson, and we stated clearly that the improvement would last only if our measures were continued by the local authorities. Later in 1902, however, Logan Taylor reported that these authorities did not appear very anxious to continue them; and we consequently closed the work when our money was expended —having done, we thought, as much as private persons could do.1 After my third visit to Freetown, Prince August d’Arenberg, President of the Suez Canal Company, asked me to advise regarding the prevention of malaria at Ismailia on the Canal. I arrived there in September 1902 with Sir W. Macgregor, who did me the honour to accompany me. The town was swarming with both Culicines and Anophelines; and efforts to control the malaria by liberal quinine distribution had not succeeded. I advised a continuance of this measure with general mosquito-reduction. In this case “intelligent and persistent efforts ” were made ; and within a year the insects of both groups were almost entirely banished, and the ad¬ missions for malaria reduced from about 2,000 a year to 214. Since then, endemic malaria has entirely disappeared. Dr A. Pressat says that he originally reduced the disease by means of a mosquito brigade of only four men qui a tout fait [1904]. Scarcely less brilliant was the campaign at Klang and Fort Swettenham in the Federated Malay States, commenced in 1901, and carried out chiefly by Dr Malcolm Watson. At Hong Kong also, a campaign was commenced at the same time, and carried out chiefly by Dr J. C. Thomson with very good results. Several anti-mosquito campaigns have been con¬ ducted in the United States; and in 1906-1907 my brother, E. H. Ross, acting under the orders of Sir Horace Pinching, 1 A year later it was pretended that our efforts had failed, and the only thanks which we ever received for our pains was a subterranean effort to injure us.
