The layer that was transplanted to the vineyard grew well, and in 
1912 ten branches were bagged before any buds had opened. Again, 
none of these flower clusters set fruit, and no fruit developed on the 
exposed branches of the vine. 
In 1913 ten branches with a total of twenty flower clusters were care¬ 
fully bagged, and this time eight of the ten bags contained some fruit. 
The whole vine had a fair sprinkling of fruit. 
In 1914 twenty branches witli not less than a total of forty clusters 
were bagged, and from each of these twenty bags some ripe fruit was 
harvested in the following September. The largest fruit cluster that 
was taken from these bags consisted of eight berries, while the largest 
cluster that was ever borne by the vine consisted of only ten berries. 
In 1915 ten more branches with no less than twenty flower clusters 
were bagged, and fruit was harvested from eight of these bags in the 
fall of the year. Again there was a fair crop of fruit on the exposed 
parts of the vine, and every year since then a fairly good crop of fruit 
has been produced.

From the results of these bagging experiments we learn these impor¬ 
tant facts: 
1. That the pollen of this vine, Hope, can under normal conditions 
fertilize the flowers on the same vine and on the same flower cluster. 
2. That with proper cultivation and care this vine assumes the charac¬ 
ter of a hermaphrodite vine, while with neglect its pistils gradually 
cease to function and the vine assumes the general role of one that is 
staminate. 
3. That cultivation, pruning, and general care exert a marked effect 
on the size and the regularity of the crop. 
This last point is of considerable economic importance, because the 
general belief is that varieties of rotundifolia grapes can endure con¬ 
siderable neglect and still produce good crops.
