VINES ON TRELLISES. 75 



train two horizontal thighs out of it, upon which 

 they trim in winter, four to eight spurs. Others, 

 again, trini for full bows — others for half bows, 

 with more or less spurs in all cases. The general 

 idea is, that being less restrained as to room, par- 

 ticularly along walks and around houses, less strict 

 rules are followed as to trimming, it being varied ac- 

 cording to circumstances. Summer trimming is almost 

 invariably entirely dispensed with, unless, indeed, a 

 regular vineyard is planted out upon this principle. 

 Beading the preceding pages^will indicate the general 

 rules. Instead of thighs, branches, &c., the vine will 

 then . be divided into main and side stems, and 

 branches with half bows and often even without any 

 bows, and relying for bearing wood only upon spurs. 

 Where a vine is intended to be drawn up as high as 

 the roof of a two-storied house, the vine had better be 

 trained upon the two-story principle also, by forming, 

 if I may say so, a two-storied main stem. 



To train a ^dne some twelve to fifteen feet straight 

 up, engenders its rapid growth, and imparts to it a 

 heavy, rich foliage, but such vines are seldom good 

 bearers. 



It is in accordance with long exjDerience — one that 

 has never failed — that bending the bearing wood pro- 

 motes its bearing qualities, and equally useful are all 

 checks to the too rapid upward flow of the sap.
