ning the same number of points. There are also shown similar reports 

 on the three principal propagated varieties, the Stabler, Ohio and 

 Thomas. It is to be regretted that nuts of the Ten Eyck and McCoy 

 were not at hand for similar testing. 



There are also noted the nuts which are best in the various charac- 

 teristics, even though the total number of points awarded them did not 

 bring them among the winners. The tables for using the score card is 

 also given in detail showing how from' the five weighings and three cal- 

 culations the number of points to be awarded was determined. 



The nuts were cracked on the side between two flat surfaces as here- 

 tofore. Noting how well the cracker at the meeting March 3d, 1927, 

 seemed to work, I rigged up steel tubes so as to bring pressure on the 

 long way of the nut in the same way as in cracking with that machine. 

 As'Stabler nuts were the only ones I liad in sufficient quantities to work 

 on, I used these in testing out the effect of using tubes of various diame- 

 ters. Three-fourths inch in diameter seemed the best for the Stabler. 

 The average cracking quality commercial of the one lobe type cracked 

 in his way was 100% and cracking quality absolute 52.0% just the 

 same as when cracked on end between two flat surfaces. The figures 

 for perfect form Stablers were 80% for cracking quality commercial 

 and 0.0% for cracking quality absolute, very similar to the same nut 

 cracked flat surfaces on the side, where the figures were 84.0% com- 

 mercial and 0.0% absolute. While I would not want to conclude from 

 these few experiments on one variety that there is no advantage in 

 cracking black walnuts on end between hollow, pressure-producing 

 ends, I believe that no serious error has been introduced into the 1926 

 contest because the nuts were rated on cracking on the side between flat 

 surfaces. 



The figures set down for quality and flavor of the kernel of course 

 represent my opinion but it was carefully checked with those of Dr. 

 Deming, as noted on the letters, and those of Dr. ^Morris, Dr. Smith and 

 Mr. Reed as noted on the tags. Where there was a diff'erence the nuts 

 were gone over again and in many instances the figures changed. It 

 was noticed that my estimation of highest qualitj' corresponded quite 

 closely to Dr. Deming's notation of "mild," while those he noted as 

 "rich" I had set at 22. The nut which the others had estimated highly, 

 and which I could not put among the winners, was the Fritz (28).
