required it is better to purchase the stock from nurserymen. One- 

 year-old seedlings cost from $2 to $3 per thousand. 



The green ash does not cast a heavy shade and comes into leaf late 

 in the spring. Close planting on well-prepared sites is advisable in 

 prairie regions. If planted pure, the spacing should be 4 by 4 feet 

 or 4 by 6 feet, but if mixed with other species, 6 .feet apart each way 

 is preferable. Green ash will thrive better and produce a straighter 

 trunk when planted with some other tree. One of the best mixtures 

 is green ash and hackberry. Other desirable species for mixtures 

 are box elder, white elm, Scotch pine, and red cedar. If grown in 

 pure stands the green ash may be underplanted with chokecherry or 

 wild plum. These trees will endure the shade and keep the ground 

 free from grass and weeds. 



CULTIVATION AND CARE. 



The plantation should be cultivated until the crowns of the trees 

 spread out so as to form a complete shade. If the object of the 

 plantation is the production of fence posts, pruning is of importance. 

 Careful pruning will greatly increase the clear length of the trunk 

 and also increase the supply of first- class post timber.
