The two outstanding facts in the history of malaria in Algeria 

 during the years 1916-1917 are the epidemics that broke out in the 

 departments of Algiers and Oran in 1916 and 1917 respectively. These 

 epidemics, by their gravity, have had an important effect on the 

 economic life of the regions attacked ; happening at the time of 

 agricultural operations, thoy have hindered the planters, who were 

 frequently rendered short of labour. The mortahty among the natives 

 increased in Algiers in 1916, and in Oran in 1917, fatal cases among 

 Europeans being equally numerous. Both outbreaks were due to 

 abnormal rainfalls in June, that in 1916 transforming a plain in 

 Algiers into a sheet of water more than 2| square miles in extent, 

 which became the breeding-place of innumerable Anophelines. 

 Accessory causes were the neglected state of the canals, ditches and 

 drains, there being a shortage of labour due to war conditions ; storms 

 and wind, which, in the opinion of the inhabitants, brought great 

 flights of the insects in October ; the rapid increase in summer of 

 numerous green algae in the breeding- places of Anophehnes, especially 

 those of Anopheles macuUpennis. 



A. turlchudi [Pyretophoras myzomyifacies), already recorded from 

 the Sahara and the coast, was found in 1916 at an altitude of 3,100 feet. 

 No connection could be traced between the increase of malaria and 

 excavations of the soil during the two years of the epidemic. There 

 seems to be no foundation in fact for the view that the outbreak was 

 due to importation by infected French and Serbian troops from 

 Macedonia, since there was no correlation between the geographical 

 distribution of these and that of the malarial epidemics of 1916-17, 

 which must thus be accounted for by the exceptional meteorological 

 conditions of those years.
