Inspection'' where none exists or "milk from herds that are free 

 from tuberculosis," unless the herd has recently passed the tuber- 

 culin test. A person has no right to say that a herd is free from 

 tuberculosis because his stable is well lighted, ventilated and 

 drained, and his pastures are on high land. A herd may be badly 

 diseased with tuberculosis where just such conditions exist. Ke 

 has no right to tell his customers that his herd is free from tuber- 

 culosis unless he has taken all known means of finding out this im- 

 portant fact. There are many herds where tuberculosis does not ex- 

 ist and it will not develop in such a herd unless it is brought into it. 



In a large herd where cows are being purchased in the open market 

 to take the place of unprofitable animals, it is very unusual to find 

 such a herd free from tuberculosis. New cows are not in every in- 

 stance free from tuberculosis even if they were tested and passed as 

 sound at the time of sale, because the disease may be in the incuba- 

 tive stage when they are first tested. Such cows should be tested 

 again in from one to two months. These cows if left in the herd 

 for a year or more might infect a large percentage of the herd. 



AVe hope that the time will soon come when every first-class dairy 

 in the State can produce Certified Milk and get Certified Milk prices 

 for it. 



OPPORTUNITIES IN DAIRYING FOR YOUNG MEN OF 



ABILITY. 



By PROFESSOK JOHN W. DECKER, Ohio State Universltu. 



There are two things that I believe in. I believe in the dairy 

 business and I believe in young men. If I did not believe in them 

 my position as professor of dairying in an agricultural college would 

 be untenable and my work a failure. My subject conceives young 

 men. Old men have their habits fixed, and it is hard work straight- 

 ening an old tree, but a 3'oung man is still plastic and has life before 

 him. I want to assure you that it is interesting work shaping 

 thought and action of a young man into the channels in which they 

 will run through the years of a busy life. My subject has to do also 

 with young men of ability. A pretty poor stick is he who has no 

 ability. Every man has some ability though it may be of different 

 kind or degree from that of another, so my subject is not for a 

 limited class but is general. The extent of one's ability is measured 

 bv the keenness and definiteness of thought, and the measure of this 

 keenness and definiteness of thought is often expressed in material 

 things. A man works on the street digging ditches. It requires 

 a great deal of muscle, and some mental effort to dig the ditch ac- 

 cording to directions. He gets at the rate of a dollar a day and 

 at the end of the week gets six dollars in money. That six dollars 

 represents stored up energy physical and mental. The money is 

 simply a medium of exchange by which he can exchange his effort 

 or energy for some other person's effort and money is a means of 

 measuring the effort of different men in terms of benefit to the 

 world. The more the world needs a certain kind of effort the greater 

 is the money — or material value placed upon it. The man who works
