Description and Classification 27 



Fitch says that the varieties Rural, Early Ohio and 

 Irish Cobbler are the outstanding varieties of Iowa. In 

 regard to the others, he makes the following comments : 



"The following are grown in Iowa to a greater or less 

 degree or reach our markets. 



" Green Mountain, the second most important variety 

 in the United States, and a second best late sort for Iowa. 



" Burbank, still the standard of the U. S. Government 

 for market quotations, formerly important in Iowa, and 

 at some seasons still important in the supply of her cities. 



" Peerless or Pearl, by test at Ames, ranking among the 

 best late sorts, and often coming into her markets from 

 Colorado or Wisconsin. 



" Bliss Triumph, sometimes grown in Iowa for very early 

 use, and extensively grown in the South for the supply 

 of the early markets of Iowa and the northern states." 



William Stuart of the United States Department of 

 Agriculture has recently made a very comprehensive and 

 admirably arranged classification of potatoes. His bulle- 

 tin contains not only a valuable key, but a careful descrip- 

 tion of our standard varieties of potatoes and points out 

 many unnecessary synonyms. The reader is referred 

 to this bulletin for this storehouse of information on 

 potato varieties. 



Stuart gives the following classification key : 



Stuart's classification
