two or even three buds on each spur, so as to form two or 

 three bearing shoots from each, in order to obtain a fuller 

 crop. This is, however, dtawing too severely on the vine for 

 continued practice. To maintain the vigor of the vineyard, 

 as well as to obtain large, well-developed, well-ripened 

 bunches and berries, the vin^ should never be over-cropped ;

and one shoot from each spur is, therefore, sufficient. The 

 reports which are often made of six, seven, and eight tons of 

 g^rapes from an acre, may be set down as evidences of bad 

 management and over-exhaustion of the vines. Three to four 

 tons per acre is the largest amount which good and continued 

 success will warrant. 

 By raising bearing shoots from the same spur for successive

years, this spur will become lengthened several inches, or at 

 the rate of about one inch annually. Although little incon- 

 veniences result, it is desirable to keep them short ; and for 

 this purpose the spur may be cut back to one of the smaller 

 btids at its base, and a new shoot thus brought out to form the 

 beginning of a renewed spur. As this new shoot springs from 

 a small bud, it should not bear any fruit the same season, but 

 its whole strength be given to the formation of wood to furnish 

 next year's bearing shoot. By selecting each year a small
