3. Disinfect the premises. 



This procedure should be executed \vi1li (he most exacting 

 care. Partial or iuefticient disinfection is practically use- 

 less. To disinfect, where fumigation with the vai)or of for- 

 maldehyde cannot be employed, llic spray pump furnishes 

 the best means. It should be borne in mind that disinfect- 

 ants do not destroy germs that they do not come in contact 

 with. So, all large accumulations of bedding, forage and 

 manure should be removed and every place that may harbor 

 a germ should be reached with the disinfectant. Especial 

 eare should be used to drive it into every crack, knothole, 

 behind every loose board, on top of every beam and into 

 every partly concealed hole as well as upon every exposed 

 surface. 



A 5 per cent, solution of good (not crude) carbolic acid may 

 be used for this purpose. 



Following the disinfection by spraying and the cleaning 

 of the stable, it may be whitewashed with lime — wash con- 

 taining one pound of fresh chloride of lime to each 3 gal 

 Ions of water. This may be applied with a brush or, better 

 with a spray pump. 



The barn yard should be well cleaned out, the manur( 

 being spread in some field that the cattle do not have access 

 to. The bottom of the yard should be well scraped and the 

 earth stained with leachings from manure should be removed. 

 Then the surface of the yard may be flushed with a saturated 

 solution of sulphate of iron or thickly spread with lime. 

 The outer wall of the barn, facing on the yard, and the ad- 

 joining fences should be disinfected or whitewashed. 



4. Irrigate the genital passages of the cows that have aborted. 



The purpose of this procedure is to disinfect the genital 

 passages. A convenient method is as follows: 



Hang a bucket containing the antiseptic solution back of 

 the cow. To a spigot on the side of this bucket attach a 

 rubber hose f inch in diameter and about G feet long. Insert 

 the hose into the vagina and, if possible, into the uterus of 

 the cow. Allow from 3 to 4 quarts of the warm solution to 

 flow into the cow and out. Take a fresh hose and irrigate 

 the next cow, allowing the first hose to soak in an antiseptic 

 solution in the meantime. 



This treatment should l>e repeated every second or third 

 day so long as there is any discharge from the cow. After- 

 wards it may be used once or twice a week. As appropriate 

 solutions the following are recommended: Lysol, 1 per cent.; 

 creolin, 2 per cent.; bichloride of mercury, 1-3000; carbolic
