 giving bulky drenches it is most convenient to use a long-necked, 

 heavy glass bottle. The horse should be backed into a narrow 

 stall and the head elevated by placing a loop in the end of a small 

 rope over the upper jaw, passing the rope back of the nose piece 

 on the halter and throwing it over a beam, and raising the head 

 until the mouth is slightly higher than the throat. If tlie horse

 into the nostril. This forces it to swallow. A dreilch should
