vent practically any damage from extreme drouth, and 

 produce a most magnificent crop of corn. 



THE CORN AREA. 



The corn area is greater than has been advertised 

 Corn is not limited to a narrow belt running through the 

 country. Good corn has been grown in western Florida 

 where it was once supposed no corn could be grown. 

 Good corn is being grown every year north of the Canada 

 line. Good corn is being grown on farms far up the 

 mountain slopes of the west. This does not fit in well 

 with what the old books and newspapers have been telling 

 us. What is the reason? 



It is not that we have got new varieties of corn from 

 Siberia or Patagonia, nor is it merely that we have been 

 acclimating corn for these out-of-the-way regions, though 

 a great deal does depend on the selection of the seed for 

 corn. 



It used to be said everywhere, and it was believed by 

 everybody, that corn could not be grown where cool 

 nights prevail. Our best authorities also declared sol- 

 emnly only a few years ago, that corn could not be grown 

 north of Iowa, nor at an altitude of 2000 feet or over. 

 Now we find large yields of corn have been grown at 

 various places in North Dakota and elsewhere at an 

 elevation of over 6000 feet. At Walsenberg, Colorado, at 

 an altitude of 6800 feet, one variety of corn, an early 

 dent variety, has been grown with great success for seven 

 consecutive years. The fifth, sixth and seventh years, 

 the yield was over 40 bushels per acre. The acclimation 

 of this corn has much to do with the success achieved, 

 but the greater part of the success is due to the fact of 

 a better understanding of the soil and how to till it. 



Corn is the one staple crop on thousands of farms.
