312 GENERAL SCIENCE 



Exercises 



1. Tell what difficulties are experienced in providing and distributing an 



ample supply of pure milk in large cities. Why is it that milk more than 

 other foodstuffs may become responsible for much sickness? 



2. What constitute sanitary conditions for a farm dairy? 



3. What becomes of the cows found unprofitable for dairy use because of age 

 or other reasons? 



4. In what respects is dairy farming as a life occupation (a) rather attractive; 



(b) undesirable? In what respects is there less of drudgery about it than 

 formerly? 



5. To provide an ample food supply the year around for his cows, and to 



avoid excessive expenditures for ground feed, what crops may the dairy 

 farmer raise? 



6. Name several important considerations that largely determine whether or 

 not a region is well adapted for dairying. 



7. From livestock sold and shipped to distant packing houses for beef, what 

 is the farmer as a consumer likely to buy back eventually in one form or 

 another? Why are not all these various forms of foodstuffs and manu- 

 factured products prepared in the home community? 



8. How has it come about that both the tanning industry and the manufac- 

 ture of shoes are carried on at a few centres only, involving as this does the 

 expenses of transportation to and fro of the raw material and of the manu- 

 factured product? 



9. From what parts of the world are there importations of hides and beef? 

 10. What has caused the great increase in creamery-made butter, and the 



lessened amount of the "country-made"? Aside from the taste given to 

 butter by salt, what purpose is there in its use? 



LESSONS ON CORN 



To travel all day by train through the corn fields of the 

 Middle West at a time when the crop is in its stage of most 

 luxuriant growth gives one an idea of bounty, prosperity, 

 and promise that cannot be gained by any reading of crop 

 statistics. The development of the agricultural resources of 

 the corn-growing states of this country, and their growth in 

 population and wealth within a half century, constitutes a 

 wonderfully interesting chapter in the history of the United 

 States. They have become in a very real sense the granary 

 of the nation.
