THIRTY-SEVENTH ANNUAL CONVENTION. 179 



we know those things, gentlemen. How did our generals in the 

 Civil war handle the enemy? Did they attempt to cover every 

 portion of the enemy? They fortified the lines, the bridges, 

 the roads, the railroads, in order that they could use their ar- 

 tillery to the greatest effect. We, in order to use effective 

 measures, must concentrate our artillery. 



The tubercular organism is found in the internal organs 

 of the body, the liver, the lungs, the spleen and even the muscular 

 portions may become infected. That organism goes on, multi- 

 plies and develops until those lumps break down and produces 

 pus, in appearance not dissimilar to that you find in a boil, al- 

 though it is not quite as soft in character. This material, when 

 it is forced into the lungs, produces irritation. It breaks out on 

 the outside, or it works inwardly and that results in a cough 

 and so this material is coughed up just the same as in the case 

 of a human being. The sputum is the danger to the commu- 

 nity. The animal, however, the bovine does not expectorate, 

 but it is forced out in the act of coughing and it goes through 

 the animal into the manure and the manure is rich with these 

 germs. The coat of the animal becomes covered with this ma- 

 terial and' it drops off into the milk. 



Then again it may come through the milk itself; where 

 the disease progresses and develops in the body it reaches a 

 point where the lymph glands are affected, the blood vessels and 

 the lymph glands. The milk itself at the time it is drawn may 

 contain the seeds of the disease. So with a child where the 

 milk contains these germs it passes to the child. With a grown- 

 up person there is no danger if they are healthy, but with a baby 

 it is different. Thus it is our duty to see that our milk is free 

 from these organisms. 



The problem rests with you whether that milk does or 

 does not contain the seeds of disease which are liable to produce 

 this disease in the child.. 



You have, therefore, this expulsion, in the cough, in the 

 manure and through the milk supply. In the case of the milk 

 if it is consumed by the animal or by your child the liability of
