(Figs. 1. 2). From Fig. 2 arj Table 1 ?nd numerous similar datJ is it apparent that large yields ai secured when the average growl is between 2'/2 and 3% inches Ion This is found to be the optimu growth for several varieties, a though the lare:est yields are four on McFarlin's with somewh; shorter growths than is the ca; for Howes. The difference in opt mum growth for these two vTietii is not more than % inch. One of the principal factoi affecting growth anc production the popuplation or stand of u) rights (Fig. 2). Optimum growl and maximum production are foui when the number of uprights from 200 to 300 per square foe As the number of uprights ii creases the length of the growl also increases, apparently as tl result of .shading. As an illustr: tion, the relatively small effect ( the shade produced by sing cheesecloth coverings on four paii of "pollination cages" set up : blossoming approached, which near the close of the growir period, increased the length < growth by per cent. Thinnin the stands by pruning reduces t? amount of growth, apparently as result of increased light. In th same connection, it is interestin that mowing of very vegetati\ stands of vines gives a reduce length of growth until such tin- as high populations of uprights ai again established.
