The numbers of vines of the several varieties are too small and 

 the cause of death not quite certain enough to make definite state- 

 ments as to what stocks and what varieties were most tender to 

 cold ; but the figures in the table may be regarded as suggestive of 

 the hardiness to cold of stock and variety. These show that fewer 

 vines on St. George died than on any other stock. We should 

 not like to state it as a fact but it seems possible that the deep 

 rooting habit of this stock may have fitted it best for withstanding 

 cold. 



After the injury of the calamitous freeze had been repaired as 

 far as possible by resetting, old and new vines made a splendid 

 growth in 1905, the season being most favorable. A considerable 

 number of vines lagged in growth, however, still showing, it seemed 

 to the observers, the effects of the cold of the winter preceding the 

 last. As a commercial venture, and in the light of subsequent 

 events as an experimental one, it would have been better to have 

 dug the vines out in 1904 and to have begun anew. 



1906. — The work this season began with the filling of vacan- 

 cies, of which there were on Gloire stock, 34 ; on St. George, 27 ; on 

 Clevener, 35 ; and on own roots, 9. The dead vines were, it may be 

 assumed, weaklings injured by the freeze two winters past. This 

 was the last setting made of which any account is to be taken. 

 During the .summer, as in all past seasons, the vineyard was left 

 under thorough tillage, all suckers were removed, roots severed 

 from cions and the best cultural treatment given. The effects of 

 fidia, which had appeared in the vineyard a few years previous, 

 began this year to show very perceptibly on some of the vines. 



In the fall of this year for the first time a full record of the har- 

 vest was kept. A good many of the vines were not in bearing and 

 the ages of those in fruit were so variable that the data have little 

 value. 



1907. — No items of experimental interest appear in the 

 account of the work in the vineyard for this year. The vines are 

 reported as making a good growth and as being free from pests of 

 any kind excepting tli<e fidia and this pest seemed to be succumbing 

 to treatment and was not as bad as in previous years. During the
