 the cow may be disposed of and better returns may be had by 

 selling the farm crops and saving the labor necessary to put his 

 dairy products on the market, whether they be sold as milk, butter 

 or cheese. 



Milk and dairy products are cheap at present prices as compared 

 with many of the more common food products. Scientists like Dr. 

 R. V. McCoUum, of the Johns Ilopkins University, within the last

 known as vitamines so necessary to the proper growth of children, 

 as well as adults. 



The public must get themselves into a state of mind so that they 

 are willing to pay a fair price for dairy products the same as for 

 other food products if they expect to continue to use them as they 

 should be used. Remember there are no substitutes for dairy 

 products.
