planted, thereby indicating its age, and column 4 gives the year of 

 grafting. Column 5 shows the congeniality, or the growth of each 

 variety on the different stocks, expressed in the form of a percentage 

 rating, on a scale in which the growth of the variety when not grafted 

 but growing as an entire plant on its own root under conditions to 

 which it is well adapted is taken as the standard of excellence, that 

 is, 100 per cent. These ratings therefore represent the behavior of 

 each variety grafted on the several stocks under the conditions exist- 

 ing at the vineyard at which it was found, expressed in terms that 

 permit comparison with its behavior when growing as an entire 

 plant on its own roots under favorable conditions and not based on 

 a comparison with other Vinifera varieties grafted on the same stock 

 in the same vineyard. The rating in each case is the average 

 rating made in different seasons to and including the autumn of 

 1913. To illustrate: Alicante Bouschet, grafted in the Oakville 

 vineyard in 1906 on different resistant stocks, on Aramon X Rupes- 

 tris Ganzin, No. 1, was rated at 91 ; on Riparia X Rupestris, No. 3309, 

 at 88; on Mourvedre X Rupestris, No. 1202, at 72; and On Riparia 

 X Rupestris, No. 101, at 55. This shows that Alicante Bouschet, 

 which is well adapted to the conditions there, when grafted on these 

 different stocks at the same time, under the same conditions, in the 

 same vineyard, and with the same treatment, varied in growth and 

 behavior in comparison with the same variety on its own roots in 

 accordance with the above ratings. Column 6 gives the pruning 

 method, s being used for spurs and c for canes. Column 7 gives the 

 weight of prunings per vine; 8, the nodes bearing fruit; 9 and 10, 

 the growth-starting dates in early and late seasons; 11 and 12, the 

 blossoming dates in early and late seasons; 13 and 14, the fruit- 

 setting dates in early and late seasons; 15 and 16, the fruit-ripening 

 dates in early and late seasons. Columns 17 to 21 give the fruit per 

 vine for the seasons from 1909 to 1913, inclusive; 22, the average per- 

 centage of sugar, Balling scale; 23, the average acid, as tartaric, per 

 100 c. c. Column 24 shows the size of the clusters, m indicating 

 medium; m-1, medium to large; 1, large; v, very; s, small. Column 

 25 shows the shape of the clusters, whether round (r), cylindrical (cy), 

 long (1), or tapering (t). Column 26 designates the density of the 

 clusters, whether compact (c), medium (m), or loose (1). Column 

 27 shows the size of the berry, whether large (1), medium (m), or 

 small (s). Column 28 gives the shape of the berry, whether round 

 (r), oval (o), or oblong (ob). Column 29 shows the color of the 

 berry, whether black (b), red (r), or white (w). Column 30 indicates 

 the purpose for which the fruit is used, whether for table (t), ship- 

 ping (s), juice (j), wine (w), or storage (st). In this table the nomen- 

 clature of varieties has been brought into conformity with the code 

 of the American Pomological Society in so far as it has appeared 

 practicable.
