Greening (W. R.). Mosquito Control at Messina [Transvaal].— 

 S. African Med. Record, Cape Toivn, xv, no. 7, Uth April 1917, 

 pp. 105-107. 



Prior to the auti-malarial measures adopted at Messina, a mining 

 camp in the northern Transvaal with a population of about 500 whites 

 and 2,500 natives, an annual outbreak of malaria of more or less severity 

 occurred, especially in 1914 and 19 1 5. Hollows abound in the country 

 around the town and in a series of shallow water-holes, one and a half 

 miles to the south, Anophelines found a breeding place throughout the 

 vear. The sanitary conditions in the camp were imperfect and 

 favoured mosquito breeding, which was also promoted in the mine 

 itself. All hollows that admitted of being filled up were dealt with 

 in that manner, whilst in others the pools were oiled. Some trees were 

 found to be a source of danger, as they harbour water for a long period 

 after rain. The maroola tree is one instance of this, the baobab being 

 another. No further complaints were received from a police station 

 after a maroola tree near by was removed. This tree contained a 

 couple of gallons of water teeming with larvae. It was noticed that 

 cattle, more especially those of a dark colour, brought mosquitos into 

 camp on their coats, and for this reason water-holes at a considerable 

 distance were brought under control. Anophelines were also detected 

 on the dark helmets of police coming into camp from patrol duty. 

 As a result of the measures taken not a single locally-acquired case of 

 fever has occurred during the past and present season.

Haseman (L.). The House-Fly and its Control.— Missown Agric. 

 Exten. Service, Columbia, Circ. no. 16, April 1917, 11 pp., 4 figs. 



This is a popular bulletin on the life-history and habits of the 

 house-fly and its danger to man as a carrier of disease. In Missouri 

 there are probably 9 or 10 generations in a year. Methods of control 

 and, more particularly, means of preventing infection by the house- 

 fly are discussed. The importance of farm sanitation and the need for 

 co-operation in towns, which is essential in control of the fly pest, are 

 emphasised. All the methods of control advocated have previously 

 been dealt with in this Review.
