This elegant palm is much planted for ornament in Cali- 

 fornia and Florida. 



THE CONIFERS 



The conifers cannot be used on the street as shade-trees. 

 Their branching and mode of growth are such as to make 

 them absolutely impossible to prune. They must be left to 

 grow naturally. When growing close together in the forest, 

 a process of natural pruning goes on, the lateral limbs die 

 out for want of light and air, and the trees shoot upward, 

 producing straight, tall trunks. When growing in the open, 

 on the other hand, the lower branches commence near the 

 ground. Any attempt to remove the lower limbs disfigures 

 the tree, and, therefore, while these trees are useful and 

 highly decorative for lawn and park purposes they cannot 

 be used for the street.
