longer than it should be. The letter b shows 

 the point at which the addition was made to 

 the arnr ; and the letter a the buds on the un- 

 der side which are to be rubbed off. 



To make the matter plainer, we introduce 

 Fig. 30, a piece of an arm, with its cane, on a 

 full scale, a is the point 

 at which the cane is cut to 

 make the spur ; e and/ are 

 the two principal or pri- 

 mary buds ; b and c are 

 base buds, so called be- 

 cause situated at the base 

 of the cane. These base 

 buds vary greatly in num- 

 ber, and in some cases are 

 not apparent. All the spurs on the arm are 

 sometimes formed to produce two canes, and 

 sometimes only one ; at others, again, these two 

 kinds of spurs alternate. If we wish to grow 

 two canes, the cut is made at a if only one, 

 the cut is made about half an inch above the 

 bud f. To save repetition, we will alternate 

 the spurs in the vine we are growing, pruning 

 every other one for two canes; the canes, there- 

 fore, will be cut alternately at a and about half 

 an inch above/. We shall thus illustrate the 



Fig. 30.
