ON THE TRAINING OF VINES. 95 



orous, as to generate wild or long-jointed wood. It 

 may, also, be further mentioned, that every shoot 

 trained in a serpentine manner, ought to be wholly cut 

 down at the next autumnal pruning after it has borne 

 fruit, as the further retention of it would produce great 

 confusion in the future training of theshoots. 



Summer Training. In order that the principles on 

 which this important point of culture is based, may be 

 clearly understood, it will be necessary to point out, 

 as distinctly as possible, the circumstances under which 

 bearing- wood is produced. 



It must be borne in mind, that the fruit of the 

 vine is produced on shoots of the preceding year's 

 growth, or, in other words, the grapes that are grown 

 in the present year 1843, are produced from shoots 

 grown in 1842. Now, during the growth of a current 

 year's shoot, all the buds which it developes previously 

 to the month of August, will be fruit-buds, provided, 

 first, that the size of the shoot be large enough for its 

 vessels to convey a sufficient quantity of the juices of 

 the plant, to generate and nourish bunches of fruit in 

 embryo ; and, secondly, that the shoot be duly exposed 

 to light, and to the full operation of the sun's rays, on 

 the surface of a wall, having any aspect south of and 

 including the eastern and western points of the horizon, 

 by which these juices will be elaborated, and the pro- 

 cess of the formation of fruit-buds thereby completed. 

 If, therefore, the shoot itself be not sufficiently large 

 to develope fruit-buds, or, if being so, it be shaded from 

 the sun's rays during the first protrusion and early for- 

 mation of them, then, in the following year, shoots only 

 will be produced, but no fruit. But, on the contrary, 

 if the shoot, being of a proper fruit-bearing size, be con- 

 stantly triined on the surface of a wall, having any of 

 the aspects before-mentioned, and a clear space of five 

 inches be left on each side of it, by which no adjacent
