reduce breeding of mosquitoes, and has made reports on same for the benefit 

 of officials interested. The field staff of the board, in addition to work on the 

 projects mentioned above, has checked many projects, endorsement of which 

 was given the previous year, but the work of which was carried on during the 

 year 1936. Work on mosquito control under the supervision of the State Re- 

 clamation Board has consisted largelj' of ditching for drainage purposes. The 

 use of larvicide has been very much limited in projects in Massachusetts. 

 About the only material being used is the usual fuel oil, and in all of the pro^- 

 jects under the supervision of the board, expenditures for oil during the fiscal 

 year did not exceed $400. 



With respect to developments regarding the interrelation of mosquito prob- 

 lems and wild-life conservation, the Reclamation Board has worked with the 

 Division of Fisheries and Game of the State Department of Conservation on 

 experiments on modifying conditions in certain salt marsh areas where mos- 

 quito control ditching has made the marshes less attractive to ducks and shore 

 birds. By restricting the depth of drainage of salt marsh pools and sloping 

 the banks, the pools apparently can be made attractive to wild fowl without- 

 creating conditions likely to produce mosquito breeding. It is hoped to con- 

 tinue observations in the experimental areas during the present year to deter- 

 mine if such modifications can be safely made. The Reclamation Board has 

 endeavored to carry on the mosquito control work in such a way as to do as 

 little damage to wild bird life as possible, and has found the wild-life interests 

 willing to co-operate in a reasonable manner. 



Following are tables of expenditures for the fiscal year on projects other
