Doctor Lak.son. 'Phis cow-testin<; and hnll-association work we 

 liavc h(M>n doin<; (hlFcrs from general t>x tension work in that we do 

 not extend the rcj^idar association woik in the States except so far 

 i\s to show the people of the wState how this work can be done. In 

 other words, in your nci<rld>orhood reccTitly the county ajjent was 

 not .sohl to tlie idea of a hull a.ssociation. We think that is one of 

 the best and cheapest and surest ways of iniprovinpr the f^eneral 

 cattle of this country --throuf]:!! the hull-a.ssociation work, so our man 

 who is in tlie i)ull-association work <joes to your State extension man 

 and goes around the county and arranges a survey of the county 

 and calls on a number of the farmers and he hnds that they are in 

 terested in establishing a bull association. This county agent did 

 not know the constitution and l)y-laws. He did not know the diffi- 

 culties of organization and keeping it going afterwards, but the de- 

 partment man worked with this man long enough to establish an 

 as.sociation. He may do it in some other part of the State. 



Mr. Anderson. Do thev not have people in the State colleges who 

 do that i 



Doctor Larson. They do after you have shown them how. In 

 other words, we have men who study bull association work, make it 

 a special study for a year or two. A college man, if he were going to 

 drop all of his other work for a year, as would bo necessarv to learn 

 all the ins and outs of the bull association w'ork, could do it, but he 

 has something else to do, and our man establishes one or two associa- 

 tions and goes to some other State. That is the line he is doin^^ — 

 not to extend it all over the State as the extension work used to be. 

 It is simply showing the way and letting the State do the rest. 



Mr. Anderson. This fellow operates as a specialist, as I under-

ANIMAL .NUTRITION WORK. 



Doctor Larson. Absolutely. I briefly outlineil the work we are 

 doing in nutrition. This is fundamental work in animal nutrition, 

 and it is not simply feeding animals in the ordinary sense of the 

 word, but it is actually determining as far as possible just what 

 becomes of these feeds and what are tlie precursors to milk. We also 

 study the blood. 



They are discovering proteins, for instance, that are more valuable 

 than othei-s for milk production. You may take a feed and analyze 

 it and find it contains a certain percentage of protein, and take anotlier
