METHODS OF MANUFACTURING POTATO CHIPS. 



15 



score of 28.4 for two seasons 1 tests, 27.2 in 1916 and 29.7 in 1917. In 

 a 1-season test there was only one seedling whose total score exceeded 

 29.7, and that was S 38595 with 29.8, a difference so slight as to be 

 negligible. Many of the seedlings graded 29.0 or more, however. 

 The lowest average score' was 20.9, given to S 7322, and the lowest 

 single score was 12.3, given to S 1449. In this connection, it should 

 be borne in mind that those potatoes which were evidently unsuited 

 for chips were not subjected to this test.

 potatoes tested in 1915, 1916, and 1917.
