two vines had been broken by accident. Of the twenty-one remain- 

 ing seven showed spots of the fungus on the shoots, the remaining 

 fourteen appearing healthy. September 29, 1910, the vines were 

 removed to Ithaca and heeled in for the winter. Some vines were 

 lost in some maimer so that only fifteen vines were set in the disease 

 garden in the spring of 1911. On November 4, 1911, there were 

 eleven vines in good condition, one very weakly appearing one, and 

 three dead. It is not certain whether the three died from disease 

 or from the excessively cold winter and the late planting, or a com- 

 bination of these factors. The latter seems most probable. Octo- 

 ber 12, 1912, the following notes were made on the general con- 

 dition. Two were struck by the plow and died. 



Vine 3, good growth, two shoots infected, one ripe rot berry. 

 Vine 4, excellent growth, most of the shoots infected. 



Vine 5, excellent growth, one arm with tuberculous growth, one arm practically 

 dead. 



Vine 6, good growth, most of the shoots apparently infected. 

 Vine 7, fair growth, severely infected shoots. 

 Vine 8, fair growth, apparently a few infections on shoots. 

 Vine 9, good growth, apparently healthy. 



A similar lot of material was started in 1909 with the same end in 

 view. The record of growth to date is very similar to that already 

 given and may be chronicled here in the brief notes made from time 

 to time. 



1909, July 15, shoots marked in vineyard at Romulus, N. Y. 

 November 29, cuttings made and buried in a box in the garden. 



1910, March 31, 230 cuttings were taken to Fredonia and placed in soil. 

 June 23, most of the cuttings appear to be alive at this date. 



July 17, many of the cuttings dead. Cryptosporella present in abundance and 

 pycnidia oozing spores after 24 hours in a moist chamber. The photograph 

 in Plate IV, C, was obtained from one of these cuttings. 



August 29, only 17 plants with leaves; some others appear alive but if leaves 

 were put forth now the vine would probably winterkill. 



September 29, vines moved to Ithaca. 



1911, May 14, ten vines set in disease garden. 



November 14, eight vines now alive in the garden, the other two vines probably 

 died from severe winter and late planting. 



1912, October 12, vines in the following condition: 



Vine 1, excellent growth, apparently healthy. 



Vine 2, fair growth, apparently healthy. 



Vine 3, excellent growth, 2 dead arms, some shoots apparently affected, 



Vine 4, good growth, apparently healthy. 



Vine 5, good growth, apparently healthy. 



Vine 6, fair growth, apparently healthy. 



Vine 7, good growth, 2 dead arms, 1 shoot infected. 



Vine 8, good growth, apparently healthy.
