desired in the winter, the steaming of the wood will be found to 

 loosen the bark so that it will slip. Now hold the branch firmly 

 with the left hand and with the right make a clean, sharp cut, 

 with a budding-knife, through to the wood and one third of the 

 distance around the twig. Now, by another operation, make a 

 straight cut, about one inch in length, at right angles to the one 

 just finished. The two cuts now form a letter T (see Fig. 19). 

 With the budding-knife carefully peel the bark back, down to 

 the wood, thus breaking the cambium layer. Take a bud stick 

 which has previously been procured and, holding 

 it in the left hand, carefully cut a bud from the 

 stick. The bark, including the bud, should be 

 about one inch in length. It should contain as 

 little as possible of the wood of the stick. Now 

 insert the bud into the cut made in the stock, 

 place the bark over the bud, and tie the whole

the stock ^ sn ow first, the longitudinal and the cross cut ; 



second, the bud in place ; and third, the bud 

 wrapped. Make two natural-size drawings of the bud after it 

 has been removed from the bud stick, the first a front view, 

 showing the shieldlike shape of the portion of the bark ; the 

 second a side view, showing the width of the bark bearing the 

 bud. Label all drawings. 



PRONG, OR TWIG, BUDDING 



This is a modification of shield budding in which a short prong, 

 or spur is used in the place of a simple bud. The bud is cut in 

 essentially the same manner as for shield budding. 



Secure for your bud stick small branches of the walnut tree, 

 or any other tree having short prongs, or spurs. By the same 

 operation as in shield budding remove the prong bud. The in- 

 cision into which the prong bud is placed is identical with that of 

 the shield bud. Make two drawings, natural size, of the prong 

 bud, showing the front and side views. Label. Discuss.
