Problems in Production. 



If we are now producing annually crops on the farms valued at nine 

 billions of dollars when our population is about 100 millions ; what should 

 be the value of our agricultural products in 1950, if our population reaches 

 200 millions? 



2. There are now employed on the farms of the United' States 12 

 million laborers. If the present number of laborers, by better methods 

 of farming, could increase our production 50 per cent ; how many laborers 

 would be required to raise the production 100 per cent? 



4. If we could double our production and prevent half of the 

 amount of our annual wastes, what would be the value of our annual 

 production of crops with prices remaining the same? 



5. The national and state governments of the United States are 

 spending $40,000,000 annually to maintain the National Department of 

 Agriculture, state experiment stations, state boards of agriculture, agri- 

 cultural colleges, and for other purposes of agricultural education to pre- 

 vent wastes and losses to agriculture and to improve the welfare of the 

 country generally; what per cent is this amount expended of the losses 

 sustained by agriculture as shown by the table? 



6. Various estimates have been made of the losses occasioned by 

 bad roads, it would not be out of the way to estimate this loss at least at a 

 billion dollars annually; if there are 100,000,000 people in the United 

 States; what is the average loss per capita? 



7. According to experiments conducted in the feeding value of corn 

 in the form of ensilage, 65 per cent is in the kernel, and 35 per cent is in 

 the stalk and leaves ; when the value of the corn in the U. S. was one 

 and one-half billions as estimated in the value of shelled corn, what would 

 have been the value of the rest of the corn crop in the form of ensilage. 



8. It has been estimated by agricultural experts that at least 90 per 

 cent of the corn stalks of the country under the present system of farm 

 management are lost; what would be the gain to agriculature if the full 

 value of the stalks could be saved when the grain value of the crop is 

 valued at about the average value of the corn crop for the last ten 

 years which was 1.4 billions of dollars? 



Years ago the first settlers had before them millions of acres 

 of virgin soil. As fast as they cleared away the forest they added 

 new fertile fields to their domain, but when the forests were gone 

 the addition of virgin soil ceased and the old fields began to
