DEVELOPMENT OF FORM 



[CH. 



midal to broadly ovoid-rounded, but it is obvious that as 

 this tree developes the trunk will be more and more lost 

 in the crown, and all signs of the original symmetrical tree 

 with a principal axis running through to the top. Such 

 a type of growth is quite common in such trees or bushes 

 as the Lilac, Privet, &c. 



Fig. 29. 



It would be easy to multiply examples of this kind of 

 modification of the shape of the crown by slight, but 

 increasing, throwing of the energy of growth into certain 

 of the branches at the expense of others, in trees with 

 decussate shoots, but the space at disposal will only permit 

 of one more example of this type. In Fig. 30 a sapling 

 similar to that in Fig. 2(3 has been represented, and its 

 further development in Figs. 31 and 32, traced as before, but
