INFECTIOUS DISKASES. 509 



1. Sweep ceilings, side walls, stall partitions, flooi*s, un<l other 

 surfaces until frt^} from cobwebs and dust. 



2. Sn-iipe away all aciMinuilation of liUii, and if wcKxlwork has be- 

 come dcray«'d, porous, or absorbent, it should be removed, burned, 

 and replaced with new material. 



3. If floor is of earth, remove 1 inches from the surface, and in 

 places stainetl with uritie a sullicient de])th .should be replaced to ex- 

 pose fresh earth. All earth removed should be rei)laced with earth 

 from an unc(mtaminated sotn-ce; it would l)e better still to lay a new 

 floor of concrete, whi<-h is very durable an<l easily cleaned. 



4. All refuse and material from stable and barnyard should be 

 removed to a })lace not accessible to cattle or ho^s. The manure 

 shouM be sjnead on fields and turned under, while the wood should 

 be buraed. 



5. The entire interior of tlie stalile. especially the feeding troughs 

 and drains, should be saturated with a disinfectant, as li(pior cresolis 

 compositus (U. S. P.), or carbolic acid, ounces to every gallon of 

 water, to which 4 ounces of chloi'id of lime should be added. The 

 best method of ai)plying the disinfectant and the lime wash is by 

 means of a si:rong sjjray pump, such as those used by orchardists. 

 This metluxl is efficient in disinfection against most of the contagious 

 and infectious diseases of animals, and should be applied innne- 

 diately following any outbreak, and, as a matter of precaution, it 

 may be used onc-e or twice yearly. 



0. It is important that arrangements be made to admit a plen- 

 tiful supply of sunlight and fresh air by providing an ample number 

 of windows, thereby eliminating damj^ness, bad odor, and other in- 

 Banitary conditions. Ciood drainage is also very nece.ssary. 



If the use of liquor cresolis compositus, carbolic acid, or other 

 coal-tar products is inadniissibU- i)e< au^e of the readiness with which 

 their odor is imparted to milk and other dairy products, bichlorid 

 of mercury may be used in proportion of 1 to 800, or 1 pound of 

 biclil<»rid to 100 gallons of water. All i)ortions of the stable soiled 

 Avith manure, however, should first be thoroughly scraped and 

 cleaned, as the albmnin contained in manure would otherwi.se greatly 

 dimini.sh the disinfecting power of the bichlorid. Disinfection with 

 this material should be supervised by a veterinarian or other person 

 trained in the handling of poisonous drugs and chemicals, as the 

 bichlorid is a powerful, corrosive poi.son. The mangers and the 

 feed boxes, after drying, following spraying with this material, 

 should be washed out with hot water, as cattle are especially sus- 

 ceptible to merctirial poisoning. The bichlorid solution should be 

 applied by means of a spray pump. :i< t«'<oiiin)ended for tlie liquor 

 cresolis compositus.
