Vines on poor soil, on the contrarj;should be planted closer together and prunedshorter, or with fewer fruiting-buds, in order tomaintain their vigor. Type I.—This is the ordinary short-pruningpracticed in ninety per cent of the viueyards ofCalifornia, and is the simplest and least expensivemanner of pruning the vine. It is, however,suited only to vines of small growth, which pro-. 317.

The chief objection to thismethod for heavily-bearing vines is that thebunches are massed together in a way that favorsrotting of the grapes and exposes the differentbunches unequally to light and heat. 508 VINIFERA GRAPE TRAINING The Fig*. 317 represents the shnplest form ofthis style of pruning. The vine should be givenas nearly as possible the form of a goblet,slightly flattened in the direction of the rows. Itis important that the vine be kept regular andwith equally balanced arms. This is the chiefdifficulty of the method, and calls for the ex-ercise of some judgment. From the first, therequired form of the vine should be kept inview. On varieties with a trailing ha
