76 MODERN DAIRY PRACTICE. 



still more important, the development of micro-organisms 

 is checked for some time, as the lime-water acts as a weak 

 antiseptic. To become very effective the whitewash ought, 

 however, to be repeated during the summer. 



Disinfection of Stable. In case contagious diseases 

 have appeared in the stable since the last thorough clean- 

 ing took place, or if the milk in spite of all precautions 

 has still proved strongly infected in the stable, the liming 

 ought to be preceded by a disinfection of the stable. This 

 may be effected in various ways. I shall here describe a 

 method in use at an estate in Germany which is reported 

 to have given good results. 



After having scrubbed, cleaned and aired the stable, 

 as directed, all doors, wickets, windows, flues, etc., are 

 shut. If straw or hay is found in the mow it must be 

 removed. The less leaky the doors, etc., are the better. 

 Several earthenware plates with chloride of lime are now 

 placed in the stable and crude muriatic acid poured over 

 them. Chlorin gas is then generated, which will kill the 

 bacteria. It must be remembered that this gas is injurious 

 also to man, especially for the respiratory organs, for which 

 reason one must leave the stable as quickly as possible 

 after the addition of the acid; the stable is now kept shut 

 up for twenty-four hours and then thoroughly aired. If 

 the stable is well closed an application of one pound of 

 chloride of lime and three pounds of crude acid may suffice 

 for every 5000 cubic feet. After airing, all woodwork, as 

 window-sills, mangers, beams, etc., are carefully scrubbed 

 and washed with boiling-hot water. 



Sulphurous acid, which is generated by burning sulphur 

 in a suitable dish, has also been used for disinfection of 

 stables; it acts only in the presence of moisture. Recent
