INFECTIOUS DISEASES. 509 



1. Sweep ceilings, side walls, stall partitions, floors, and other 

 surfaces until free from cobwebs and dust. 



2. Scrape away all accumulation of filth, and if woodwork has be- 

 come decayed, porous, or absorbent, it should be removed, burned, 

 and replaced with new material. 



3. If floor is of earth, remove 4 inches from the surface, and in 

 places stained with urine a sufficient depth should be replaced to ex- 

 pose fresh earth. All earth removed should be replaced with earth 

 from an uncontaminated source ; it would be better still to lay a new 

 floor of concrete, which is very durable and easily cleaned. 



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

 removed to a place not accessible to cattle or hogs. The manure 

 should be spread on fields and turned imder, while the wood should 

 be burned. 



5. The entire interior of the stable, especially the feeding troughs 

 and drains, should be saturated with a disinfectant, as liquor cresolis 

 compositus (U. S. P.), or carbolic acid, 6 ounces to every gallon of 

 Water, to which 4 ounces of chlorid of lime should be added. The 

 best method of applying the disinfectant and the lime wash is by 

 means of a strong spray pump, such as those used by orchardists. 

 This method is efficient in disinfection against most of > the contagious 

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

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

 may be used once or twice yearly. 



6. 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 dampness, bad odor, and other in- 

 sanitary conditions. Good drainage is also very necessary. 



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

 coal-tar products is inadmissible because 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 

 bichlorid to 100 gallons of water. All portions of the stable soiled 

 with manure, however, should first be thoroughly scraped and- 

 cleaned, as the albumin contained in manure would otherwise greatly 

 diminish 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 poison. 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 mercurial poisoning. The bichlorid solution should be 

 applied by means of a spray pump, as recommended for the liquor 

 cresolis compositus.
