the stations will be glad to send him any information they 
can to help him overcome his difficulties. 
ADMINISTRATION OF MEDICINE. 
Medicines which are not distasteful can be given with the 
feed, provided the hog has not completely lost its appetite. 
Wherever possible, the administration of medicine in the feed 
is preferable to drenching. 
Dr. Craig (“ Diseases of Swine”) recommends the fol- 
lowing method of drenching hogs: 
“To hold the animal while drenching it, a noose of sash- 
cord or quarter-inch rope can be placed around the upper jaw 
well back toward the angles of the lips, and the medicine thrown 
into the back part of the mouth with a dose syringe. As there 
is danger of the hog breaking the syringe, it is best to use a 
metal one, Sometimes, when the drench is bulky and the hog 
hard to hold, it is necessary to elevate the head and raise the 
fore-feet off the ground. For this purpose a pulley and rope 
wire stretcher is recommended, It is best to wait until the 
hog has become quiet and well under control before giving it 
the drench, as there is some danger of the medicine getting 
into the air-passages and doing harm.” 
The writer has seen more than one hog killed in the opera- 
tion of drenching. If the drench is poured too rapidly into 
the throat, it is almost sure to be drawn into the lungs, and 
the hog will probably die in a few minutes. The medicine 
should be poured verv slowly, and it is best to pour it just 
inside the cheek instead of into the throat. 
Hairless Pigs.— Wisconsin Bulletin 297 deals with hairless 
pigs. Hairless pigs are of normal weight and size. They are
