the Chicago market values that I have given practically reflect the 

 differences applying to each one per cent of moisture as shown by this 

 table. 



This close comparison between the actual sales in Chicago and the 

 dry-matter basis shown by the card would not probably hold if there 

 would be an excessive volume of receipts of extremely heavy moisture 

 content corn, as the supply of that particular kind of corn would ex- 

 ceed the demand, and, as frequently occurs, the capacity of the driers 

 might not be sufficient to take care of it, consequently buyers would 

 not feel that they are safe in buying the corn with heavy moisture con- 

 tent and take the risk of storing it or forwarding it in transportation 

 with such heavy moisture content. 



I am not informed technically as to the feeding value of corn, but 

 I assume that an excessive amount of moisture in corn does not con- 

 tribute to meat production. 



If as a feeder you should buy 1,000 bushels of 24 per cent moisture 

 content corn, 8 per cent of your money would be expended for excess- 

 ive water content above the normal moisture content of the 16 per 

 cent; that is, considering that the average moisture content of the best 

 quality of corn v.'ould be about 16 per cent. 



If the price of corn is 40 cents per bushel, based on the maximam 

 of 16 per cent moisture content, your loss by excess moisture would be 

 $32 on the purchase of the 1,000 bushels. 



In other words, you should pay $32 less for 1,000 bushels of 24 per 

 cent moisture content corn than for 1,000 bushels of 16 per cent mois- 

 ture content corn, at 40 cents per bushel, in order to receive the same 

 feeding value. 



In conclusion, I want to urge upon you as growers of corn to give 

 the question of the moisture content in breeding, growing and caring 

 for the corn after it is harvested, your earnest attention, in order that 

 we may not incur further interference in the marketing of this most 

 valuable of grains by drastic pure food regulations with which we are 

 now threatened. 



Following Mr. Well's address, Mr. Brown, of Chicago, made a 

 practical demonstration of the use of moisture-testing apparatus.

BEEP MAKING IN IOWA.

How shall we feed our cattle so as to make the maximum profit? 



This is the dominant issue in beef making in Iowa. The first essential
