516 EXPERIMENT STATION RECORD. 



Until. 11 of this insect in the province <>f Kilwa as observed during the author's travels 

 in that region. The tsetse fly appears not to prefer thick brush lands, but occurs 

 in greater numbers in grass lands, especially in the vicinity of a forest. The fly is 

 not particularly associated with a swampy region, but occurs most frequently on 

 higher ground, at considerable distances from swamps. The insect is described in its 

 various stages and notes are given on its life history. 



According to the author's observations, there is no remedy which is likely to be 

 effective in destroying this pest. The adult flies may be captured in considerable 

 numbers, and this method of destruction would assist to some extent in controlling 

 the insect. Attention should be devoted chiefly, however, to the prevention and 

 treatment of tsetse-fly disease.

Irrigation in Northern Italy, I, E. Mead ( U. S. Dept. Agr., Office of Experiment 

 Stations Bui. 144, pi>- 100, pis. 18, figs. 14)- — This is an account of a study during the 

 summer of 1902 of irrigation methods and practices in Lombardy and Piedmont 

 which was undertaken in accordance with the law requiring this Office to report 

 "upon the use of irrigation waters at home and abroad," and which had for its 

 special object the obtaining of suggestions for the improvement of administrative, 

 engineering, and agricultural practices in the United States.
