 ing with the feed, to prevent and stamp out the gape dis- 

 ease. M. Megnin gives each pheasant seven and one-half 

 grains of assafoetida combined with the same quantity of 

 pulverized yellow gentian in their feed. Five to ten 

 drops of turpentine to a pint of meal and made into dough, 

 is used by some. When garlic or onions are faithfully fed, 

 the trouble is much reduced. The explanation is that the 

 volatile part of these substances, 

 being absorbed into the system, 

 is thrown off through the lungs 

 and brought into contact with the 

 parasitic worms in the windpipe, 

 to which it is fatal, and they are 

 ejected with the mucous. Meg- 

 nin recommends adding about 

 fifteen grains of salicylic acid to 

 each quart of the drinking water. 

 Prevention is better than a cure. 

 The importance of the total de- 

 struction of the parasites after 

 their removal, should be realized. 

 If the worms are killed and 

 thrown upon the ground, it is 

 scarcely likely that the mature 

 eggs will have sustained any in- 

 jury. Decomposition will set

 well as the dead bodies of anything affected with them, 

 should be burned, if we wish to prevent the spread of the 

 disease. If infected birds are buried, earthworms or 

 skunks may bring the infection to the surface. 



Pools and wet places are supposed to be favorable to the 

 preservation and development of these germs. It has often
