 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 very slowly, and it is best to pour it just 

 inside the cheek instead of into the throat.
