the average tree with possibly an idea of what the tree should 

 be like. 



THE SILVER MAPLE. 



Silver Maple generally has a fairly regular formed crown 

 if not crowded. It forks quite close to the ground, sometimes 

 within two feet of the base of the tree. It attains a height of 

 30 to 38 feet, and varies greatly in diameter. An average diam- 

 eter for a 35 foot tree is 16 inches, but may run far above or 

 below this figure. It is readily susceptible to decay if not cared 

 for. Although it is a fair shade tree, other species, such as 

 Norway or Sugar Maple, are preferable. 



THE ASHES. 



Both the Green and White Ash will be considered together 

 .as there is very little, if any, difference in the conditions of the 

 two trees. The Ashes have a very coarse spray, but due to the 

 compound leaves makes a fairly good shade tree. They average 

 about 8 inches in diameter, trees of this diameter reaching a 

 height of nearly 30 feet, and growing to a height of from 11 to 14 

 feet before forking. Ash thrives well on nearly any site in the 

 city, being well adapted to the drier sites. They usually are not 

 attacked badly by insects or fungi. 



THE ELMS. 



The White and Slippery Elms were the only species of the 

 genus studied in this survey and they were considered together. 

 These trees develop a beautiful broad topped crown with grace- 

 ful, drooping branches. The average diameter is from 6 to 7 

 inches, and the average height from 20 to 25 feet. They finally 

 attain a diameter of from 14 to 16 inches and a height of from 

 40 to 45 feet. The Elms fork at about 7 feet from the ground; 

 "but this can easily be changed to a height of from 12 to 15 feet, 

 if properly cared for when young. The trees are attacked by 

 insects to some extent, but they have not been affected as badly 

 as in some other cities. 



Box ELDER. 



Box Elder usually has a very compact but unsymmetrical 

 crown. The stem is very crooked and forks about 6 or 7 feet 

 from the ground. The tree grows rapidly but is short lived,
