the northeastern states with fresh vegetables demanded for con-

To the student who has a desire to study this region further

 the trucking soils, the topography of the region, it is advised 

 that he should read "Truck Soils of the Atlantic Coast Region"

EXERCISE. 



Secure a map of the United States. 



Draw a line from the 80th meridian at Pittsburgh, Pennsylvania, to 

 the middle boundary of North Dakota at the 100th meridian. 



Draw another line from Pittsburgh to the southwest corner of 

 Oklahoma and then draw a line from this point in Oklahoma north on 

 the 100th meridian to the point where it will intersect the line from 

 Pittsburgh to the northern boundary of North Dakota. 



PROBLEMS. 



1. Find the length of each of the three sides of this triangle. This 

 may be found approximately by using the scale on the map. 



2. How many sq. miles of land are included within this boundary? 



3. What part is this of the land area of the United States? 



4. What part is this of the land area of the globe? 

 The population of this region is about 30,000,000. 



The Banner Region in Agriculture. 



Within this area is produced one-half of all the corn in the 

 world. 



This region also produces one-third of the hogs, one-fifth 

 of the cattle, one-fourth of the meat, one-fifth of the oats, one- 

 eighth of the wheat, and one-tenth of the horses of the world. 



This is the region of greatest opportunity in the world, be- 

 cause we can more than double the production per acre, within 

 a very short term of years.
