At the close of the season, this long ri-pened shoot or cane has produced a bud everyfoot or less, from which new fruit-bearing shootsare to spring next year. But if all these budswere allowed to remain, the vine would be over-taxed with fruit the coming year, and the cropwould be a failure. The cane is, therefore, cutoff until it bears only as many buds as experi-ence has taught us the vine should carry. Thecane may be cut back to five or ten buds, andperhaps some of these buds will be removed, or HOW THE FRUIT IS BORNE 405 rubbed off, next spring if the young growtliseems to be too thick, or if the plant is shoot will bear, on an average, two orthree clusters.

The number of clusters which a vine^can carry well depends upon the variety, the ageand size of the vine, the style of the training,and the soil and cultivation. Experience is the 406 AMERICAN GRAPE TRAINING only guide. A strong vine of Concord, which isa prolific variety, trained in any of the ordinarysystems and set nine or ten feet apart each way,will usually carry from thirty to sixty clusters will weigh from a fourth to a halfpound each. Twelve or fifteen pounds of mar-ketable grapes is a fair or average crop for sucha Concord vine, and twenty-five pounds is a verj^heavy crop. The pruning of the grape vine, therefore, isessentially a thinning process. In the winterpruning all the canes of the last seasons growthare cut away except two to six, whi
