MOSQUITO CAMPAIGN
 TO WIPE OUT FEVER
Experiments in Suez Canal Country
 Are Successful.

Under the title of "The Prevention of Fever on the Suez Canal" F. H. Ross has published an important ac- count of the details of the campaign against mosquitoes which was con- ducted under his direction at Port Said, and subsequently, at Ismailia, and which has afforded invaluable experience of the methods most cal.- culated to be successful in other localities
 Commencing with the European quarter at Port Said, the whole of the district to be treated was divided into seven portions, each of which was visited once a week by the mosquito brigade, which entered ev- cry house and renewed the supply of oil by which the larvae lurking in cesspools and other receptables were destroyed. The success attained was so marked as to induce the inhabit- ants of the native quarters to ask for the extension of the resulting benefits tO themselves. and to waive the objection to the admission Of of- ficials into their houses which they would in the first instance have en- tertained; so that ultimately the whole of Port Said could be effec- lively dealt with.
 The inhabitants had been accus- toned to suffer frequently from fever" of a somewhat obscure type. which was sometimes called "dengue," and was usually treated successfully by quinine. but which had not been recognized as mosquito until q, those pests revealed the truth. Every one was accustomed to take quinine on the occurrence of any symptoms of fever, and hence the blood of the patients contained no parasites, 1 and it was said that there was no i malaria in the town.
 Find Parasites in Blood.
 The discovery of some specimens | of anopheles modified these views. | and led to a search for parasites in l the blood of native children, to whom | quinine is never given, and in whom | they were found to be abundant | True. dengue was also prevalent, and | came in epidemics, communicated by gnat called Culex fatigans, which | was common in the town, so that single imported case might become the source of many others.
 There was also a common form of what was called simple continued fever" the cause of which is still unknown, but which affected whole households or workshops, and which. after continuing for four days, was followed by severe prostration often lasting for a considerable time.
 During the summer of 1907. after mosquito reduction had been in prog Il ress for a year. it was noticed that the levers were disappearing. An epidemic of dengue occurred in other parts of Egypt, but Port Said es- capped.
 Some of the doctors complained that their practices were diminish ing. The life of the town became more active. visitors increased in there was more going on, and people were not as i'll as they used to be: but it was with chill dren that the change was most ap- parent. These, before the campaign was started, were always ailing dur ing the hot weather, and the infan- tile mortality was enormous. Now they are we'll and strong, with some color in their cheeks. able to play upon the beach and the schools are better attended
 The deaths during 1908 were 150 below the annual average for the last five years: while the popula- ion increased steadily and the town S growing in size.
 Abolished in IsmaiIia.
 In Ismalia, under the strong gov ernment of the Suez Canal company. l still more decisive result has beef cached. for both mosquitoes and ma aria have been abolished; but this of things is only maintained ,y constant vigilance. There are still
