man and made him responsible for its condition. In 1914, however, 

 a district was covered by a squad and the squads shifted from one 

 district to another. Countj^ C has adhered to the plan of assigning a 

 certain territory to one inspector and holding him responsible for its 

 condition. 



It should be said that the inspector is not a permanent employee 

 and that his tenure begins and ends with the mosquito breeding season. 

 Two to four inspectors are usually kept on throughout the year for the 

 purpose of doing ditching and filling work and to serve as teachers for 

 the inexperienced men of the larger force. 



Of the total expenditures the percentage devoted to inspection shows 

 considerable variation. In Count}^ A 18 per cent and 20 per cent were 

 devoted to inspection in 1913 and 1914 respectiveh"; in Count}^ B 45 

 per cent, 31 per cent, 24 per cent in 1912, 1913 and 1914; in County C 

 24 per cent, 28 per cent and 33 per cent in 1912, 1913 and 1914. 



Elimination 



Under the term elimination is included all those operations of drain- 

 ing, filling, oiling, cleaning and stocking with fish that are necessary 

 to do away with mosquito breeding places. All the small jobs are 

 attended to by the inspectors as they go about their duties, and a very 

 considerable part of this work is thus cared for under the head of in- 

 spection. The treatment of the larger places is a matter for laborers 

 employed by the commissions or for doing under contract. 



A large share of the funds go to this work. In County A 63 per cent 

 and 61 per cent were used in 1913 and 1914; in County B 33 per cent, 

 51 per cent and 54 per cent in 1912, 1913 and 1914; in County C 59 

 per cent, 46 per cent and 40 per cent in 1912, 1913 and 1914. Of the 

 total expenditures for elimination only a part was used on the upland, 

 the rest being expended on the salt marsh. Of the expenditure for all 

 purposes, in County A 31 per cent and 32 per cent were used for elim- 

 ination of upland breeding places in 1913 and 1914 respectively; in 

 County B 19 per cent, 21 per cent and 23 per cent were used in 1912, 

 1913 and 1914; while in County C 32 per cent, 31 per cent and 21 per 

 cent were employed in 1912, 1913 and 1914. 



Thus it appears that about half of all expenditure is devoted to 

 elimination of large breeding places, and that of this amount about 

 one-half goes to the upland.
