They represent very fairly the average condition of the various plats 
on July 10. 
From July 7 until September 17, when the fruit was gathered, the 
vines received no treatment. Following the plan adopted in Vineyard 
1 the fruit clusters were counted and weighed, the classification being 
the same in both cases. In the table below, the total numbers of clus- 
ters is first given; then follows the number of perfect, part-pertfect, 
and worthless clusters in the order named; finally, the percentage of 
perfect clusters is given.

A comparison of this table with that on page 28 is very interesting. 
First, it will be seen that a considerable number of clusters on both the 
treated and untreated plats disappeared. Second, the number of worth- 
less clusters increased to a considerable extent, especially on the plats 
receiving the late treatments. Third, and finally, the per cent of per- 
fect fruit on the plats treated early with full and half strength slightly 
increased, while on most of the other plats there was a decrease. As 
a final arrangement of the treatments with respect to their efficacy as 
preventives of rot we have the following, 100 representing perfect:
