it in quality, and, if necessary, in quantity, as she ap- 

 proaches the time of calving; by this means the extra 

 demand of nature in the increasing size and wants of 

 the calf will be supplied without at all affecting the 

 health or strength of the mother — thus insuring a 

 natural parturition. Third, dry up milk in all cows 

 that do not in the natural order of things stop secret- 

 ing milk, say three months before their time of calving, 

 by giving sulphate of iron three drachms combined 

 with half ounce of gentian root (each finely powdered) 

 once daily, mix in feed for one week, no milking should 

 be done other than to prevent injury to the udder if it 

 becomes distended. Fourth, mix one ounce of pure 

 carbolic acid with one pound of lard and smear with a 

 paint-brush over an after-birth that is adhered. Keep 

 your sick cows away from your healthy ones, partic- 

 ularly those that have lost their calves by abortion.

 might ask him some questions instead of simply having 

 his paper read. For my part I do not agree with his 

 opinions; my experience has been different. He rec- 

 ommends dicing up a cow r three months before she 

 calves. I do not agree with that in the first place. Of 

 course no man can tell all the causes of this disease, but 

 we do know one thing for certain, that it is very con- 

 tagious ; that if one cow is affected with it the chances 

 are that there will be more in the same herd, and if we 

 escape it w T e escape it by very great precautions, just as 

 we can only escape an epidemic of cholera by very great 

 precautions. The remedies suggested by Dr. Powell are 

 not the remedies that I have employed. I presume they 

 are good, but they are not what I use. I use a vaginal in-
