been planted with trees set out at a distance of 2>2, 3, 3%, 4, 

 5, 6 and 7 feet apart. Some plots are all box-elder, others all 

 ash and others all elm. Then there are plots with box-elder 

 and ash in alternate rows, box-elder and elm, etc. 



In the transplanted plots >the trees set out 2% and 3 feet 

 apart, cover the ground in the least time and require less 

 cultivation than those set out at greater distances apart. 

 Besides this the trees attain height more quickly and are 

 more suitable for transplanting, and no doubt as they develop 

 will make better trees for any purpose. 



Trees, at a greater distance than three feet, have a tend- 

 ency to throw out branches from the bod}^, and expend their 

 strength in breadth insteed of height. This is especially 

 true of Box-elder and Kim. 



Plantations of box-elder and ash, 1 tree of the former to 

 2 or 3 of the latter, do much better than all box-elder or all 

 ash. With "all ash" plantations there is not sufficient 

 ground protection from the sun early in the season and with 

 Box-elder there is too much. Both together afford sufficient 

 protection, and at the same time permit light and air to 

 enter. For the same reason Box-elder and Elm, in the pro- 

 portion mentioned, do better than all Kim. 



Native Ash (Fraxinus Americana) is, I think, the most 

 valuable tree we have for forest cultivation. Although slow 

 of growth for a few years it takes a smaller amount of moist- 

 ure and less cultivation, and will, no doubt, live in our dry 

 climate many years longer than Box-elder, Poplar or Cotton- 

 wood, and at the same time be more useful for fuel or other 

 commercial purposes.
