GREEN ASH. 
Native green ash was used for timber-claim planting more exten- 
sively, perhaps, than any other one species. It grows slowly, but is 
hardy with respect to both drought and cold. The tough, straight- 
erained wood has considerable value and is frequently used for fence 
posts. Ranchmen say that a seasoned ash post will last about ten 
years. 
Green ash is a fine street tree. It is easily trained to excellent form, 
attains a good height, and has a neat, clean appearance. Borers are 
the principal drawback, with some trouble from leaf-aphis and heart- 
rot. The ash borer is not nearly so serious as the black-locust borer, 
but it has done much damage in some localities. The green ash is 
frequently called ‘“ white ash ” by tree planters and even by nursery- 
men, 
Ash responds well to good care, and the slow average growth given 
in the table is due to the fact that many of the measurements were 
made in neglected plantations. In the valleys, under the most favor- 
able conditions, the tree may grow an inch in diameter in two years, 
while in neglected upland growths it sometimes requires nime years. 
The growth in plantations is generally much slower than in the case 
of well-cared-for rows and individuals in parks and along streets. It 
is doing well at Cheyenne Wells, Colo., thus showing that care is 
more important than climate. 
The following table gives upland measurements. Whole groves 
were not measured, but enough individuals were taken in each case 
to insure a fair estimate.
