it will be well to add three drams of salicylate of soda 

 to each quart of drinking water. Affected chicks will 

 need radical treatment. Take each chick separately 

 and remove the worms from its windpipe. This can 

 be done with a strip of feather. Take a long slender 

 feather, and tear off all the barbules except those at 

 the tip. Mix a little oil of clove and sweet oil. Moisten 

 the feather tip with this, and insert it gently into the 

 windpipe of the chick. Twist the feather around 

 several times, and withdraw it. If you have operated 

 successfully you will draw out most of the worms with 

 the feather, and the oil will kill the others which may 

 have been left behind. After a little practice the 

 operation is easily performed, and does not seem to 

 trouble the chick much. It is seldom necessary to 

 repeat the operation. Clove oil is used with the sweet 

 oil because it has been found that its use is followed 

 by less irritation that when other lubricants are used. 

 The bodies of any birds which may die of gapes should 

 be burned, all worms removed, and all excrement of 

 affected birds should be burned also. 



Hazvks are often troublesome but can be fre- 

 quently caught in an ordinary steel trap, not too large, 

 mounted on the top of a common fence rail or a long 

 pole, set firmly in the ground. It is best located on 

 some moderately high point in the middle of a wide 

 field, where there are no trees or other objects upon 

 which a bird may light. No bait is needed. The trap 

 is simply opened on top of the pole, where the bird 

 sets it off and is caught in the act of alighting. Fig- 

 ure 117. Of course the trap must be firmly secured to 

 the pole. The device is based on the principle that 

 birds of prey habitually light on prominent objects in 

 large open spaces, where they will have a good outlook 

 for game. A trap well placed will, during one season, 

 catch all the hawks within a radius of several miles.
