 homed, from willow fence posts, and from the 

 stumps of felled oaks and maples. The latter 

 show brilliant bits of color in tha early summer 

 and fall. Always adventitious buds make a 

 remarkable growth, because of the extensive 

 root system which finds it but child's play to 

 bring up material for these few shoots, after 

 having once supplied the needs of many 

 branches. 



Yet another kind of bud is the "summer" 

 bud. In August we find it on the same- branch 

 with the winter bud. Its business is to pro- 

 mote the growth of the young shoot, so it does 

 not need to be made into a parcel, and devotes 

 all its time just to stretching out. With some 

 trees the growing season is very short, with 

 others, like the staghom sumach, the locusts, 

 and the catalpa, it lasts until frost kUls the 

 ambitious buds. It is the summer buds which 

 tip the yellowish-green and rosy shoots of young 

 saplings and the branches arising from stumps. 

 They persevere until blighted by the cold. Be- 

 side the topmost spring buds of the late growing 

 branches is always a little black scar — ^"the

 If in latter summer a branch top is broken off,
