APPENDIX. 



THE following tables are prepared merely to facilitate selections of trees and shrubs on the 

 basis of size and growth alone. Deciduous trees are arranged by classes in three tables, as follows : 

 First, DECIDUOU* TREES OF THE LARGEST CLASS. Second, DECIDUOUS OF SECONDARY SIZE. 

 Third, DECIDUOUS TREES OF THE SMALLEST CLASS. The usual growth, under good culture, 

 at twelve years from the seed, is approximated ; and the ordinary height and breadth the tree 

 attains at maturity, in the latitude of New- York City. Evergreen trees and shrubs are divided into 

 three similar classes, except that evergreen shrubs are included with the smallest evergreen trees. 

 Deciduous shrubs form a separate class, with their development indicated at six years after plant- 

 ing such plants as are usually received from nurseries ; and also at maturity. These estimates of 

 size are all based on a supposed good soil and culture ; and for specimens having an open exposure. 



The trees are classed as of the first, second, or third class, in size, on the basis of their entire 

 weight. The Lombardy poplar, for instance, by height belongs to trees of the first class, but by 

 breadth ranks with the smallest ; it is therefore put between the two extremes in the second class. 



When trees are budded or grafted on other stocks, as many weeping trees are, the age of the stock 

 is included in the age for which estimates of sizes at twelve years from seed are given. But as such 

 " worked " trees are grafted at quite different heights on stocks of the same age, it must be under- 

 stood that the estimates here given are for trees grafted in the manner most common in the great 

 nurseries. Trees marked with a star * are those generally grafted on other stocks. 



It must not be inferred that these tables embrace all the trees described in the preceding work. 

 Most of the leading species are represented by one or more out of many varieties. The 

 species and varieties which are not included in the tables will be found at once by referring to the 

 INDEX.
