buckets or refuse buried, the pit should be sealed with sackuig to 

 prevent flies emerging through the earth. 



Various methods of trapping the fully-fed maggots, based on their 

 migratory habit before pupating, are noticed, and the usual methods of

Malaria is common in the southern third of Illinois, and this paper 

 describes a mosquito survey in two or three representative towns, 

 particularly Carbondale. Accurate estimates of the number of malaria 

 cases ;n this town were not available, but this is probably about 2 or 

 3 per cent, of the population a year. The survey was carried out in the 

 usual way, the district being mapped out and the various types of 

 breeding places considered. The species of Anophelines found were 

 Anopheles quadrimaculatus, Say {guttulatus, Harris), and A. pnnctipennis, 

 the former being rare. A. punctipennis seems able to adapt itself to all 

 kinds of breeding places. The usual anti-mosquito measures, namely, 

 the drainage of breeding places ; keeping the margins clear of vegeta- 

 tion ; oiling ; the use of larvicides ; the screening of houses ; fumiga- 

 tion of rooms ; and the use of repellents [R.A.E., B, vi, 69] are described. 



Report from the Select Committee on the Spread of East Coast Fever 

 in the Union, together with the Proceedings of the Committee, 

 Minutes of Evidence and Appendix. Pretoria, 15th July 1920, xvi 

 + 152 pp. [Received 23rd August 1920.] 



The investigations of the Select Committee appointed in South 

 Africa to inquire into the continued spread of African coast fever 

 in the Union are reported fully, and many examinations of farmers and 

 others who have had practical experience with the disease are given 

 verbatim. The history of the disease in South Africa, the losses to 

 the country, remedial measures in the past, and the present situation 

 are discussed. 



As a result of these investigations and in view of what has been 

 done in America and Australia, the Committee recommends that the 

 Government be requested to consider the advisability of : — 



(a) Estabhshing a separate section in the Agricultural Department 

 for the express purpose of combating and preventing the outbreak 

 of African coast fever, and appointing a capable, energetic and 

 firm ofl&cial with wide experience of the disease as the head of 

 such section, who shall be responsible directly to the Minister for the 

 carrying out of the regulations, (b) Placing the local administration 

 of the tick fever regulations in the hands of the resident magistrate 

 of the district, (c) Making the local veterinary officer advisory to 

 the magistrate (thereby relieving him as far as possible from administra- 

 tive office work), and providing him with motor transport to get into 

 closer touch with farmers, and not only to perform the proper functions 

 of his office in tendering advice, but also to check the field administra- 

 tion of the magistrate, (d) Selecting as inspectors and cattle-guards
