fertilizer another tract to receive the treatment usual in that vicinity. I do 

 not call that a scientific experiment or a method of scientific research; I do 

 call it a demonstration. That is where we may differ as to definitions. We 

 have done the same work in the orchard. As ii pertinent example, our horti- 

 culturists at the beginning of the nineties went down into southern Ohio and 

 persuadetl a large apple grower to spray a part of his orchard with the then 

 new Bordeaux mixture. He was unwilling to lislc his whole orchard, and he 

 sprayed al)()ut a third of it. and the contrast between the two portions was 

 such that it figured out to him .$.500 that first season, and he has been an enthu- 

 siastic si)rayer from that day to this, reporting his annual profit from spray- 

 ing at $1,.jOO to .$2,000 a year. He only became convinced through seeing along- 

 side of his unsprayed trees the trees that had been sprayed under our direction. 

 That was in no sense a scientific investigation. We certainly induced him to 

 make what he might have called an experiment, but which was to us simply a 

 demonstration of what we expected to be the outcome, and which was the out- 

 come of his work. 



Now, we expect to make each of the thousands of farms which we hope will 

 take up this work which is being carried on l)y our department of cooperative 

 experiments — a department which is supported entirely from State appropria- 

 tions for that specific purpose and not at all from the Hatch fund — a point of 

 demonstration, and a point, we hope, of education to the people around it: and 

 to a certain extent we hope tliat these people will become experimenters. We 

 hope that because no man can make progress in agriculture in our day unless 

 he is more or less of an experimentei' — I want to use another term : unless he 

 has more or less of the spirit of scientific research — and we hope he will take up 

 that work and carry it forward. But the work which he may do is a work of 

 demonstration to himself and his neighbors of principles which we have previ- 

 ously worked out at the experiment station in connection with these adjunct 

 farms. 



C. G. Hopkins. We hardly feel that we can separate experiment from demon- 

 stration. I might say that if we go out on a certain area, and take 40 acres of 

 corn, or a 40-acre tract of land, no matter if we have in mind simply exijeriment 

 and discovery — which we never do have in mind — that becomes a demonstration 

 to all the people in that section. We do not separate it and do not want to 

 separate it. We feel that it is more economical to do the two things at once, 

 and we do some things 100 or 200 miles away from the university that we 

 l)()ssibly could do at the university in order not only to discover truth, but to 

 demonstrate it to the people of that section. 



Furthermore, while I can not quote exactly the language of the Hatch Act, I 

 believe our State law is copied in part from it, and I know our State act says 

 '• for discovery and dissemination ; " and we take any means of dissemination. 

 If the best means of disseminating a truth is to go right in the field and demon- 

 strate it and teach it to the people of tlmt section, we use (mr State funds for 

 that just as freely as we do for experiments in the laboratory : and I believe we 

 use the United States funds just as freely. I will not state this positively, but I 

 believe the Hatch Act says " dissemination " as well as " discovery." 



W. H. Jordan, I just want to say another word. I get troubled sometimes 

 over what I might speak of as the responsibilities of the institution I am in 

 charge of. And I have had quite a good many arguments with my friends and 

 colaborers in my State over what its resiionsibilities are for education or in 

 the way of dissemination. It seems to nie entirely clear that the function of 

 the station is. first, to find out things, and then to see that they are properly 

 pl.-iced before the public. But what constitutes i)roi)erIy i)lacing them before the 

 public? There is where the ditticulty comes. I sometimes have troubles with
