large majority of cars belong to race B, to which it was assigned 
in the Rural New Yorker description. Some few ears, however, 
were of race A. It is possible that the race B varieties of the 
Black Mexican furnished the pollen which produced the black 
-ears as in No. 1838, we had unwittingly this type. In 1883 Cros- 
by’s Early did not receive the Black Mexican kernels, and hence 
would have been placed in race B, where it belongs by de- 
scription. | 
Gotpen Sweer.—In the Rural New Yorker classification, I say, 
“this variety is about equally eight-rowed and ten-rowed and 
varies in sample ears from section A towards section B. It is 
probable that selection would readily produce an eight-rowed and 
twelve-rowed sort.’’ Neither in 1883, nor in 1854, did this 
variety receive black Mexican kernels. With my present knowl- 
edge I must call this variety an anomalous type, and must await 
further study. 
Porrsr’s Excrrstor. — This is a variety which varies considerably. 
In 1883 it did not receive the Black Mexican kernels, as was like- 
wise the case with the sample in 1884, but did receive a few soft 
kernels in one sample of 1884. It propably belongs to race C, as 
grown by its originator, and as described in Lewral New Yorker, 
while the Station samples as unquestionably belong to race B, 
both by description and by the test of hybridization. 
Rocurstrer. — This is the same as EKight-rowed Early, as is not 
alone recognized by its appearance, but also as acknowledged by 
its distributer. It is negative evidence only that puts it in race B, 
and it undoubtedly belongs to race A. 
Squantum — Unquestionably of Race C type, both by description 
and the hybridization test, in samples grown in 1883 and 1884, 
and was placed in race B, in the ural New Yorker classitication 
by error. 
AmpBer Cream. — In 1883 some black, sweet kernels noted, which 
would place it in race A. It is said to be a cross between JMJoore’s 
Early and Briggs’ Harly corns of race A and race B type. We 
ean only account for the discrepancy by the presence of Black 
Mexican, race B, pollen, for the description of both years would 
place: it in race B. 
In the Golden Sweet we have a yellow, sweet kernel. This yellow 
kernel appeared on the Hickox, Marblehead, Moore's Karly and 
Stowell’s only of the sweets, all of the same race. 
Proposition. — Current cross-fertilization is facile between 
varieties of the same race. 
If we examine the records of our trials we will find that wher- 
ever we have a test or witness variety present, there seems to be fa-
