1 6 American Grape Training. 



each bearing ten buds. We will call these canes 

 A and B, respectively. (Fig. 3.) In 1892, there- 

 fore, twenty shoots grow from them, and each of 

 these shoots or new canes branches, or produces 

 laterals. We will call these new canes of 1892, 

 A I, A 2, A3, B I, B 2, and so on. Each of the 

 new canes bears at the base about two clusters of 

 grapes, giving a total yield of about forty clusters. 

 These clusters stand opposite the leaves, as seen 

 in fig. I. In the axil of each leaf a bud is formed 

 which will produce a cane, and perhaps fruit, in 

 1893. If each of these new canes, A i, A 2, etc., 

 produce ten buds — which is a moderate number — 

 the vine would go into the winter of 1892-3 with 

 200 buds for the next year's growth and crop; but 

 these buds should be reduced to about twenty, as 

 they were in the fall of 1891. That is, every year 

 we go back again to the same number of buds, and 

 the top of the vine gets no larger from year to year. 

 We must, therefore, cut back again to two canes. 

 We cut back each of the original canes, A and B, 

 to one new cane. That is, we leave only A i and B i, 

 cutting off A 7, A 3, etc., and B 2, B 3, etc. This 

 brings the vine back to very nearly its condition in 

 the fall of 1891; but the new canes, A i and B i, 

 which are now to become the main canes by being 

 bent down horizontally, were borne at some dis- 

 tance-^say three or four inches— from the base of 

 the original canes, A and B, so that the permanent 

 part of the vine is constantly lengthening itself.
