NATURE-STUDY REVIEW [14:5— May, 1918 



Accounts 



D. Other Garden Facts. In 1889 there were 889 varieties. 

 New varieties are obtained from seed. Some varieties never 

 produce fruit; others do not even blossom. 



Two crops are grown in one year on the same land in the South. 



1 900-1 9 10. The average acre yield in United States was less 

 than 93 bushels. 



1900-1910. Average acre yield in Germany and Great Britain 

 200 bushels. 



E. H. Grubb, "Potato King" of Colorado, produces 600 bushels 

 per acre. Earl of Roseberry, Potato wizard of Scotland, 2000 

 bushels per acre! Germany yields one-fourth of the world's crop. 

 We consume 3^2 bushels per person a year in the United States. 

 We import about one-fourth of potatoes used in United States. 

 There is no garden crop for which spraying is so necessary as for 

 the potato crop. 



The best potatoes are about 12 ounces, somewhat cylindrical, 

 shallow-eyed, and white in color. 



E. Pictures. Collect pictures as well as specimens to show 

 varieties, diseases, different characteristics, machinery for culti- 

 vation, and methods of caring for the crop. These may be 

 arranged in the booklets. Obtain Millet's "The Angelus", 

 "The Potato Gatherers", and "Going to Work".
