TESTING GRAPE VARIETIES IN THE VINIFERA REGIONS. 
17 
These adaptability ratings therefore represent the behavior of each 
variety under the conditions existing at the several vineyards ex- 
pressed in terms that permit comparison with its behavior elsewhere. 
They are not based on a comparison with other varieties in the same 
vineyard. Each variety is therefore rated on a scale based on its 
own standard of excellence rather than on any arbitrary scale for- 
mulated for application to all varieties. It is believed that this 
method renders possible a truer expression of the reaction of each 
variety to different soil and climatic conditions than would be pos- 
sible by using any arbitrary scale of measurement of growth. 
To illustrate, Aramon X Rupestris Ganzin, No. 2, planted at each 
of three experiment vine}^ards in 1904, at Fresno was rated 97; at 
Livermore, 83; and at Lodi 7 only 46. This shows that at Fresno 
the growth was very satisfactory, and it was therefore rated at 97. At 
Livermore the growth was good, but not nearly so good as at Fresno; 
it was therefore rated at 83. At Lodi it made a very poor growth, 
which as compared with the growth made at Fresno was as 46 to 97, 
or when compared to perfect growth as 46 to 100, i. e., 46 per cent.
