DISCUSSION OF RESULTS. 
The records of the same variety for the same season in different 
localities will first be considered to see what influence a difference 
in locality appeared to have on the degree of self-fertility. 
At Penn Yan the self-fertilized Niagara clusters were nearly 
compact enough, on the average, to be called marketable; at 
Branchport they were slightly looser. At Penn Yan, Vergennes 
covered clusters averaged nearly half-filled, but at Branchport the 
covered clusters on the average were about one-fourth filled. At 
Penn Yan and at the Station, Worden self-fertilized gave nearly 
perfect clusters, but at Branchport only moderately compact. clus- 
ters. At Penn Yan self-fertilized Diana gave perfect clusters, but 
at Branchport its clusters averaged but little more than half 
filled. At Penn Yan self-fertilized Prentiss on the other hand 
bore only moderately compact clusters, while at Branchport it 
bore nearly perfect clusters. At Penn Yan, Lindley, out of 25 
covered clusters, produced fruit on but one and that bore four 
berries; 25 clusters covered at the Station gave no fruit. At 
Penn Yan 25 covered clusters of Brighton produced but one fruit; 
at Branchport 5 clusters were covered and 3 produced fruit (see 
Plate LI, Figure 1); at the Station 27 were covered but no fruit 
formed, : 
It appears from these records that some varieties show a differ- 
ence in the degree of self-fertility which they possess in different 
locations. On the other hand other varieties which were tested 
in the same season in the different locations gave practically simi- 
lar results in different localities. Brighton, Catawba, Concord, 
Delaware, Diamond and Salem gave practically similar results for 
the same variety at Penn Yan and at Branchport. Moore, Early 
and Worden gave similar results for the same variety at Penn Yan 
and at the Station. 
Some of the varieties tested at Penn Yan and Branchport were 
not tested at the Station the same season, but were tested there in 
various other seasons. In these cases the differences in environ-
