AT PORT SAID AND ISMAILIA 21 



The cesspools were old and leaky, and in many 

 houses had burst into the cellars, and there the 

 mosquitos were breeding in myriads. 



New-comers felt the effects of mosquitos most. 

 They were inexperienced in the use of mosquito 

 nets. They forgot to tuck them in under their beds. 

 They were bitten terribly. Their faces would some-

 insects. Children especially suffered. The old resi-

 was bitten too, although he did not feel the bites 

 so much ; he was used to them. Only the mosquitos 

 themselves were really happy. 



Mosquitos were abolished, and that was the end 

 of the trouble. Malaria had been already abolished 

 at the neighbouring town of Ismailia, and we followed 

 suit at Port Said. All kinds of mosquitos were dealt 

 with as at Ismailia, and the town is now free from 

 fever carried by these insects. It has made a great 

 difference to life there. In the course of the 

 mosquito campaign several interesting facts were 

 brought to light. Malaria was found ; the cause was 

 Anopheles maculipennis and Cellia pharoensis both 

 species were found breeding in dirty water. The 

 most insanitary places were discovered and dealt 

 with. The presence of a few Phlebotomus flies and 

 an occasional case of three-day fever, which is con- 

 veyed by them, were noted. These small blood- 

 sucking flies breed in stone walls, their eggs and 

 larvae being found in tiny crannies in the stone. 

 The culex fever disappeared ; so did the dengue ;
