divisions, while the black oak 

 has five. However, the leaves 

 of these two trees vary consider- 

 ably, and one must always look 

 for the typical leaf, which is the 

 one shown in the sketch. The 

 black-jack is a small, shrubby 

 tree, with branches often twisted 

 and contorted, and its wood is 

 not very valuable except as fuel 

 or for making charcoal.

 tral view shows vertical cut at center of tree. View on right shows verti- 

 cal cut between center and bark as illustrated in Fig. 73.
