nursery (see Fig. 18). When cut off in this way, the 

 branches should not be allowed to grow in a cluster at the 

 top, as in Fig. 24, thus forming a fork which is sure, sooner 

 or later, to break down from weight of foliage, crowding of 

 branches, or ice and snow. Many trees grow up with forked 

 branches not very far from the ground, as shown in Figs. 

 20 and 21, which when they reach large size will split down 

 and thus ruin the whole tree. In this case the smaller of 

 the two forked branches should be cut away at line , the 

 head be cut back if needed, and a perfectly formed tree 

 will be the result. This fork is sometimes near the 

 ground and the sooner one of the trunks is cut away the 

 better. In Fig. 17 is shown a one-sided tree, which may
