by horse and cultivator, wMch, when well done, leaves very little 

 hand-work; but it should be often repeated during the summer. 

 For all the vigorous, hardy varieties, the Kniffen system of pruning 

 and training is probably best (see Fig. 1), which represents a line 

 of posts and two wires, respectively 3 feet and 5|- feet from the 

 ground, with an arm of young wood, 4 feet long, running each 

 way oa each wire. Now if we have 6 shoots on each arm, and a 

 pound of grapes on each shoot, you see we have our 20 lbs. and to 

 spare; indeed, sometimes 40 lbs. are produced, but 20 are enough. 



FIG. 1. 



After the fall of the leaf in November and December, prune out 

 the bearing arms, leaving 4 new arms for the bearing wood of the 

 coming crop. 



For the Delaware, Prentiss, and similar vines, a different mode 

 is better, viz. : as seen in Fig. 2. Here we have our vines 6 feet 

 apart in the row, with only a single arm of 1 year's growth, trained 

 vertically (see A), 6 feet high. The laterals from these upright 

 arms, A B, bear the fruit, C C, and after fruiting are cut away near 

 the ground at D, and renewed by young arms each year for the next 

 crop, as at A. By this method 10 lbs. are expected, and fruit of the 

 best quality. This class of vines requires better fertilization and
