136 AISTNUAL EEPORTS OF DEPARTMENT OF AGRICULTURE. 



OTHER WORK. 



Various remedies and methods of treatment for intestinal worms 

 in hogs were tested. Oil of chenopodium was found to be the most 

 efficacious of the remedies tested. The dose is 45 drops for a pig 

 weighing from 50 to 100 pounds. Each pig should be dosed sepa- 

 rately, and should receive at the same time about an ounce of castor 

 oil. Mixing the remedy with slop or ground feed and thus dosing 

 a number of hogs at once was found to be unsatisfactory. 



Further investigations on anthelmintics and methods of treating 

 live stock for internal parasites have been begun, with the view of 

 establishing the relative value of the numerous remedies which may 

 be used against parasites and of determining the best methods of 

 administration. 



Certain studies on the nematodes of rodents, tapeworms of carni- 

 vores, discodrilid worms, Fasciola Tnagna in sheep, Syngamus laryn- 

 geus in cattle, the dog as a carrier of parasites, the life history of 

 Gongylonema^ and abnormalities in tapeworms were completed and 

 have either been published or are ready for publication. 



Examinations were made of 120 imported sheep dogs with refer- 

 ence to the presence of parasites injurious to live stock, particularly 

 the gid tapeworm. Fifty-three of the dogs were found to be in- 

 fested with parasites, and of these 14 harbored tapeworms, none of 

 which, however, were gid tapeworms. Seventy-two examinations 

 were made of dogs allowed entrance into establishments operating 

 under Federal meat inspection for the purpose of destroying rats. 

 In 21 of the examinations parasites were found, but tapeworms were 

 present in only 2 dogs. 



The division has cooperated with the Insecticide and Fungicide 

 Board by testing various proprietary articles for which claims were 

 made by the manufacturers with reference to their use as remedies 

 for external or internal parasites of live stock, and an expert witness 

 was supplied to the board in one case tried in the courts. 



As usual, numerous inquiries from correspondents in all parts 

 of the country concerning parasites and parasitic diseases of live 

 stock were received and replied to, and numerous specimens of para- 

 sites were identified for members of the field force of the bureau, 

 stock owners, veterinarians, physicians, and others. 



THE MISCELLANEOUS DIVISION. 



The Miscellaneous Division, of which Dr. A. M. Farrington is 

 chief, was organized July 1, 1914, and is charged with attention to 

 miscellaneous correspondence and other matters which it is not prac- 

 ticable to have handled by the other divisions. It keeps records and 

 prepares data pertaining to the various projects of the bureau. It 

 maintains records and conducts correspondence regarding civil- 

 service examinations for positions in the bureau, appointments to 

 such positions, promotions, demotions, transfers, removals, the con- 

 duct of employees as to efficiency, the acceptance by employees of 

 outside employment, and other matters relating to the general subject 

 of personnel. It also conducts correspondence and makes tours of 

 inspection relative to the supervision which the bureau maintains 

 over veterinary educational institutions under department regu- 

 lations.
