TWELFTH ANNUAL YEAR BOOK— PART IV 161 



Professor King : Of course you understand that side of the 

 question, but that is something that I can't answer. 



H. C. Wallace : Let me make a remark here. In our case be- 

 fore the State Kailroad Commission on this minimum Aveight 

 case, the railroad attorneys tried to make the commission believe 

 that all of our stock feeders were getting rich. We summarized 

 a large number of experiments which had been published, includ- 

 ing these Indiana experiments, and made calculations, taking 

 into consideration the interest, insurance, and all the elements 

 that enter into this matter, and introduced them in evidence in 

 this case a couple of weeks ago. Our testimony before the com- 

 mission showed that on a margin of $1.50 between the buying 

 and selling price, the feeder was losing money under conditions 

 this year. We had some difficulty in making some of the rail- 

 road attorneys believe that, but I think w'e convinced the com- 

 mission that that was correct. We argued that $2 difference 

 was necessary for the feeder to come out fairly. 



Mr. Murray : Have you made any test on the question of the 

 comparative values of linseed meal and cottonseed meal? 



Professor King: We have not. I was at the Missouri station 

 for a while, and there we fed about fifty or sixty bunches of cat- 

 tle on blue grass pasture and made comparison between cotton- 

 seed meal and linseed oil meal. We found that w^hen cattle are 

 twenty months of age or over there is not a great deal of differ- 

 ence, pound for pound, between linseed meal and cottonseed meal, 

 but when the cattle are younger than eighteen or twenty months 

 the linseed meal is worth a little bit more, pound for pound, be- 

 cause it doesn 't have any poisonous properties at all ; and on 

 our results we figured that if there is not more than $4 a ton 

 difference in the cost of the two, we should feed the linseed oil 

 meal if the cattle are younger than eighteen months. 



Mr. ^Murray : I was speaking of dry feed. 



Professor King: I wouldn't venture, except on the basis of 

 the grass results, because we have made no direct comparison 

 with dry feed. 



A Member: How about the effect on hogs of the cottonseed 

 meal in the droppings"? 



Professor King : I know of one or two men in our state who 

 reported that their hogs did not do well when they fed cotton-
