for a moment. I have found it economy to have my herd 

 examined by a veterinary surgeon of acknowledged skill, 

 and, on his declaration that my herd was free from disease, 

 have obtained from him the following certificate, which I had

 the care and disposal of milk, for, if this is not of our 

 subject, it is pertinent to it. Have a milk room, if possible, 

 entirely separate from every other apartment, and allow 

 nothing to be kept in it but milk and its receptacles. I 

 need not say anything here of the necessity and wisdom of 

 taking the milk from the barn with the least possible delay, 

 for upon that point we are all agreed ; but let me speak

 volatile odors. The mechanical contrivance for the accom-
