the clusters which failed to set fruit. It is best to make such rec- 
ords early in the season because late in the season it may be in- 
possible to decide whether the absence of a cluster means that it 
failed to set fruit or that the cluster was accidentally broken off. 
After the fruit ripened each cluster was rated on the scale of 100 
according to the percentage of a full cluster of fruit which was 
found, as has already been stated under “‘ Plan of Work.” The 
detailed records are here given for each variety together with the 
records which the same variety has made in previous years when 
tested as to its self-fertility. Unless otherwise stated the tests here 
reported were made in 1899. 
‘The results are summarized and presented graphically on the 
pages following the discussion of the separate varieties. 
AMINTIA, 
Amina self-pollinated.— In 1892, 2 clusters of Aminia which 
were kept covered during blooming season gave no fruit; in 1898, 
_9 clusters which were likewise tested eave nodenws, Unies, 
6 clusters of Aminia at Highlands were hand-pollinated? with 
Aminia pollen brought from the Station, but no fruit set; 10 clus- 
ters which were kept covered during the blooming season were 
rated 0, 0, 0, 0, 0, 0, 0, 0, 0, 12 respectively. Average rating 1.2. 
So far as tested Aminia is practically self-sterile. 
Amimia pollinated with Brighton.—Six clusters tested at High- 
lands were rated respectively 0, 0, 0, 0, 0, 10. Average rating 1.7. 
Amma pollinated with Wyoming.— Five clusters tested at 
Highlands were rated ‘respectively 0, 0, 0, 0, 20. Average rat- 
ing 4. 
Aminia pollinated with Nragara.— One cluster tested at High- 
lands rated 80. | 
2 By “hand pollinating,” is here meant brushing the clusters with the open 
flowers from another vine of the same kind, and then inclosing the pollinated 
cluster together with the cluster which furnished the pollen in a bag accord- 
ing to the method followed in the 1899 experiments in cross-pollinating, as de- 
scribed on a preceding page.
