TUMORS 



Animals are afflicted with tumors of various kinds about the same 

 as are found in man. Some are malignant, others are harmless so 

 far as the usefulness or life of the animal is concerned. It is not pos-

 of tumors without laboratory assistance.

MILK HYGIENE 



The work of milk hygienve in Pennsylvania is divided into several 

 phases and placed under the jurisdiction of different divisions of the

 agents have been trained to assist dairymen and farmers in solving

 instances, dairy farmers who contemplate remodeling barns or
