THIRTY-SEVENTH ANNUAL CONVENTION. 327 



Farm No. i produces 994 pounds of milk per acre, or 3 

 pounds more than System No. 1, but at an outlay of $400 for 

 feed. Farm No. 2 falls short of System No. 2 by 134 pounds 

 of milk per acre and an annual expenditure of $500 for feed. 

 Farm No. 3 spends $1,100 annually on concentrated feeds, which 

 System No. 3 supplies from the 12.5 per cent of its area devoted 

 to alfalfa. The excess in pounds of milk in farms No. 3 and 

 No. 4 over Systems No. 3 and No. 4 may be accounted for by 

 the fact that but few calves are raised on farm No. 3 and none 

 at all on farm No. 4. These farms compare so .closely to the 

 systems in percentage of acres devoted to the various crops and 

 the returns received per acre, that they may well be taken as 

 examples of the system in actual practice. 



Many think that alfalfa cannot be grown successfully in 

 Illinois, but it is being grown to advantage in nearly every coun- 

 ty in the state and meeting with but few failures where intelli- 

 gently sown on well-drained land, if the soil has been properly 

 prepared. We have had from 10 to 45 acres of alfalfa growing 

 on the dairy farm at the University for the past eight years and 

 but one piece has winter killed during this time. 



Wonders of increased production have been worked on 

 many dairy farms by getting better cows ; and it is here shown 

 that amazing results may also be obtained by following a better 

 system of cropping. It must be remembered that all results in 

 this bulletin are comparative. 



The value of the different commodities which the farmer 

 receives from the farm without being charged to it, such as 

 house rent, fruit, garden truck, chickens, eggs, milk, etc., are 

 figured as balancing the general running expenses of the farm 

 outside of the interest, labor, etc. 



The most important portions of the following table are the 

 pounds of milk produced per acre, money value of this milk, and 

 amount left for profit in each system, all of which are printed in 

 bold- face type to show the relative efficiency of the four sys- 

 tems.
