 brought within easy reach. Now introduce the oiled feather into the 

 windpipe and carefully twirl it round and round, by this procedure

The water given to fowls to drink, when an epidemic of " gapes " 

 prevails, should be drawn from ta})S and renewed daily. If tap water 

 cannot be given them, water drawn from ponds or wells should contain 

 salicylate of soda in the proportion of 3 teaspoonfuls to a qviart. 

 Salicylate of soda kills the embryos, and it is not inadvisable to put a 

 little of it into every drinking vessel. All birds affected should be 

 isolated and kept in as small an enclosure as possible, preferably one 

 with a brick floor. The floor should be washed daily with strong 

 solutions of phenyle, as this destroys the coughed up worms and 

 embryos. Poultry should be kept off marshy places as it is in such 

 spots that they pick up the embryos, either free, swimming or enclosed 

 in the bodies of snails, &c.
