 consists of a piece of rubber tubing about 3 feet

 fastened to a post. The flow of liquid through the 

 tube is controlled by pinching the rubber tubing 

 near the point of union with the metal tube. It is 

 important not to raise the animal's head too high 

 on account of the danger of the dose entering the
