finger into the fauces to rouse the reflex active emesis. Usually 

 the crop can be quickly and satisfactorily emptied in this way. 



When this proves impossible there remains the operation of 

 direct incision through the walls of the crop and the evacuation 

 of its contents. This can be done by a pocket-knife or even a 

 pair of scissors. The crop is punctured in its lower part and the 

 incision is continued upward as far as may be necessary to allow 

 the escape of the contents. Usually half an inch will suffice. 

 Then the crop is squeezed so as to press the contents through this 

 opening and it is emptied by a process of enucleation. If the 

 contents are fibrous it may be necessary to employ forceps to- 

 dislodge the material. The empty crop may be washed out with 

 tepid water, any food attached to the raw edges of the wound 

 must be removed and the skin stitched accurately together. 

 The wound rarely fails to heal by first intention. To avoid 

 stretching it, the food for a day or two should be restricted to 

 milk, gruels, or a little soft mash.
