would not let us fairly test the matter in his section of the State. lie furnished 

 part of the fertilizer, and we furnished the rest. We did all the work. This 

 farmer is now demonstrating to the farmers of Jackson County. Mich., the 

 practicability of using the finely .ground phosphate rock. 



In the matter of animal industry we have certain difficulties (uivironing the 

 whole proposition which have niiule us reluctant to undertake any demon- 

 stration work whatever. In some i)arts of the State God has tested the powers 

 of man severely hy giving him a soil to work on which possesses nothing but 

 sand and wind. In that particular part of the State live stock does not 

 nourish. At the college we undertook some experiments to find out why the 

 live slock does not flourish and we came to cei-tain conclusions. The station 

 went up in that country where a silo was unknown and built a silo, and I am 

 here to say that the results of the demonstration were extremely satisfactory, 

 financially, to at least three counties in the State of Michigan. On the station 

 farm we do not consider it beneath our dignity to carry on considerable demon- 

 stration work. For instance, in the matter of legumes, in the matter of seed 

 selection, we like to demonstrate on the station farm, because it is close at hand, 

 \k-hat our station has done and what other stations are doing and have done in 

 this matter : but we keep this work entirely divorced from the experiment- 

 station work. 



W. II. Jordan, of New York. I Itelieve I fathered this suitject which is before 

 you by ]>roposing it at the last meeting, and your discussion has taken some- 

 what the turn I expected it would. I have heard a definition here from 

 Professor Corbett of what is demonstration work. Now. I expect we will have 

 to give an arbitrary definition to that. Possibly I can illustrate what I mean. 

 Some years ago the problem of red spot in cheese came up to us in the State of 

 New York, and we had first to determine what red spot is. That was laboratory 

 investigation. After determining the nature of the trouble, then we bad before 

 us the additional problem of how to get rid of the trouble, or control the trouble 

 in the factories. We continued our work until we believed we had a method, 

 and then went into the factories. To do what? To demonstrate the applicability 

 of the method to connnercial conditions. Now, according to Pi'ofessor Corbett, 

 that would be experimental work, because that was the last step in our solution 

 of the problem. His definition, however, of demonstration would be this, I 

 suppose, that after having taken the last step in a few factories, and showing 

 the applicability of the method, if we were then to distribute ourselves to the 

 various portions of the State and repeat that whii-h we knew would happen, in 

 a merely educational way, that that alone is demonstration work. Now, I did 

 not have that restricted definition in nnnd when I propo.sed the problem. 

 Demonstration work seems to me, as I suggested the problem, that last step of 

 demonstrating in some form the final relation of a theory or a process to prac- 

 tice. I'ossibly that had better be included in experimental work, and let demon- 

 stration work cover merely that which is extension work or educational work. 

 That is for us to determine. But tli(^ larger question which comes up to me is 

 not how we shall define demonstration work, but where the limits of experiment 

 station work shall be. That is the larger problem with us in New York. And 

 the way in which we settle that (piestion will be determined. I suspect, to some 

 extent by the i)lace that the matter of expediency has in our minds. Now, 

 academically sjjcaking. I hold that the projier function of the experiment station 

 ceases wlien we have shown in a suHiciently extensive and practical manner, so 

 as to leave no (piestion. that our theory or our method is applicable to practice 

 in a profitable way — or an uni)rofitable way. as the matter may be determined — 

 ;ind when we go beyond that we have stepped into the educational field, the 

 field of merely teaching that which i;? known. Of course the experiment station
