five and seven-tenths inches in sixteen years. The wood of this- 

 species is chiefly valuable for fuel. On land which would other- 

 wise remain idle and where the value for fuel is sufficiently 

 great, this species can be planted and grown at a profit. 



The Box Elder, Green Ash, White Elm, and Catalpa have 

 not made good growth. The Russian Mulberry which was also 

 planted in mixture as a nurse tree has assisted in establishing a 

 good forest floor. 



In 1907 experiments were started to determine the effect of 

 different spacing on height and diameter growth. The trees 

 are still too young and have not made growth sufficient to state 

 accurately the comparative merits of wide and narrow spacing. 

 There are, however, evidences of considerable difference which 

 have already been brought out in the experiments and which 

 are shown in the following table : 



The Ash in Sub-lot 3 with 4x4 foot spacing have attained 

 an average height growth which is 93 per cent of the height 

 growth in Sub-lot 1 with 6x6 foot spacing. The average D. B. H. 

 of the trees in Sub-lot 3 is 85 per cent while the diameter 1.5 

 feet from the ground is but 76 per cent of the respective diam- 

 eters of the trees in Sub-lot 1. There seems to be a very evi-
