Taking up now the next phase of the question, 7, e., the number of 
clusters on each plat. and also the number of perfect, part-perfect, and 
worthless clusters, we have the following table:

perfect, and diseased clusters, and per cent of perfect clusters, September 17.

A comparison of these figures with those in Table 4,made on July 7, 
brings out some interesting points. In the first place it will be seen 
that the total number of clusters did not materially change, the loss 
being only 235, or 0.40+ per cent. There wasa considerable change, how- 
ever,in the figures in the second column and a decidedly marked onein 
the others. Take plat 3, no treatment. On July 7 there were 240 per- 
fect, 71 part perfect, and 29 worthless clusters on these vines. September 
17 there were 146 perfect, 68 part perfect, and 116 worthless, an increase 
in worthless and a decrease in perfect clusters of 296 and 40 per cent, 
respectively. 
The per cent or perfect clusters on the treated plats, taking themasa 
whole, was 89.6 against 94.5 when the count was made on July 7. On 
the untreated plats the per cent was 41 against 61.4 July 7. As pre- 
ventives against rot the final arrangement of the fungicides, based 
on the figures in the preceding table, is as follows:
