with self-boiled lime-sulphnr used with the arsenate. It was further 

 found that self-boiled lime-sulphur used without arsenate of lead 

 gave practically the same results as where the two substances were 

 applied together. The spraying with areenate of lead alone pre- 

 vented a large amount of injury by the curculio. Spraying with self- 

 boiled lime-sulphur filled the wounds made by the curculio and thus 

 prevented the growth of spores in these wounds. 



The veterinarian did some work in testing commercial toxins and 

 antitoxins, and began an invastigation of autogenetic serums. Some 

 work was also done for the State board of agriculture on hog-cholera 

 serums. The animal husbandman reported that in in-and-in breed- 

 ing exi:)eriments with hogs thus far no evil effects have been noticed. 



The station has no definite cooperative work with farmers or other 

 stations, but the station veterinarian is working in cooperation with 

 this department. No well-defined extension work is done, as funds 

 have not been provided for it, but occasionally members of the staff 

 deliver addresses at institutes or farmers' gatherings. On Farmers' 

 Day, June 13, 1910, a large number of visitors inspected the station. 



The following publications were received from this station dur- 

 ing the year: Bulletins 86, Crimson Clover — Its Eate of Gaining 

 Nitrogen; 87, Two Important Leaf Miners; and 88, Annual Report 

 of the Director for 1909. 



The income of the station during the past fiscal year was as follows: 



United States appropriation, Hatch Act $15,000.00 



United States appropriation, Adams Act 13, 000. 00 



Farm products 608.42 



Total 28,608.42 



A report of the receipts and expenditures for the United States 

 funds has been rendered in accordance with the schedules prescribed 

 by this department and has been approved. 



The Delaware station is making good use of the funds at its dis- 

 posal in the conduct of experiments and investigations of substan- 

 tial character. Its relations with the instruction work of the college 

 are such as to allow its staff to devote their attention very largely to 

 the station activities.
