4. OESTKLCTION OF TllK KU.Mi' GLAM). 



There is a gland at the point of the rump that se 

 cretes an oily substance that tends to keep the feal It- 

 ers in this region oily and sleek. This gland is the 

 largest of the superficial glands of the body and some- 

 times the orifice through which it discharges its secre- 

 tion becomes obstructed. Then the region of the 

 gland swells and becomes painful. It may swell to 

 such an extent that it reaches the size of a walnut. 

 This causes considerable ])ain. the afflicted fowl be- 

 comes sluggish and generally indis^wsed and when it 

 is caught and examined (he local swelling can be 

 readily discovered. 



If the gland cannot be emptied by gentle pressure a 

 small incision should be made into it with a sharp 

 knife and its contents removed. If, however, the con- 

 dition has existed for a long time, the gland may fill 

 with a thick, clu-esy-like material that cannot be 

 S(iueezed out. It then becomes necessary to make n 

 somewhat larger opening and scoop the substance out 

 with the handle of a small si>oon or some similar ob- 

 ject. Then the cavity shonld be washed nut l.v in 

 jecting into it a very weak solution of carbolic acid 

 (i part of carbolic acid to 200 of water"!, or a solutioTi 

 of boracic acid (15 grs. to the ounce). To prevent the 

 parts from becoming hard while healing an applica- 

 tion of oil or cosmoline should be made.
