have plenty of sunlight to destroy the germ that is destroying the 

 hen. Then ventilate the house and remove the droppings often. 

 If you have a valuable hen, quarantine her by removing her from 

 the flock, then mix one part of carbolic acid with ten parts of lin- 

 seed oil and sponge the head and face of the hen. We call it 

 " carbolized oil." 



Will sour milk cause indigestiou when fed to calves? 



Mr. Cook. — Not if fed carefully. As a rule, indigestion is caused 

 by over-feed or by feeding too rich milk to young calves. But I 

 would not feed very sour milk. There is a tendency on the part 

 of most of us to over-feed the calf. I believe that mildly soured 

 milk will not injure the calf, but I should prefer not to give the 

 calf milk until it is two or three weeks old, milk containing more 

 than two to three per cent, butter fat; later, I would feed skim- 

 milk, sweet.

Is it well to give a horse linseed oil in his feed as oil meal? If so, how 

 much would you give? 



Dr. Smead^ — Oh, no; linseed meal is a food very rich in protein^ 

 which makes blood, bone and muscle. Linseed oil is a medicine 

 which is used sometimes in veterinary practice.

Is there a preventive of the " Buffalo fly? " 



Prof. Felt. — I know of no remedy. Lime sprinkled on the drop- 

 pings is doubtless the best preventive. We may keep the stable 

 dark during the day, or spray with kerosene oil, but most of these 

 remedies are only temporary. 



Is there any remedy or preventive of the railroad worm in apples? 



Prof. Felt. — The only remedy is to destroy the fruit, pick up 

 the apples and feed them to hogs. Spraying will not affect the 

 apple maggot. It will the codlin moth, however. We know that 

 the moth does not fly far, so that if one takes care of his orchard, 

 even if his neighbor neglects his, the insect may be quite largely 

 obliterated in any one orchard.
