Seed spots with red oak and black walnut have given good results, but 

 with hickory have practically failed. It might be mentioned, however, 

 that planting hickory has not been any more satisfactory on the sites 

 where it has been tried. 



In the first plantings of conifers, where the soil was cultivated, 2-0 

 stock was used throughout, but where the grub hoe method is used, 

 stronger stock has been found necessary, especially on the heavier 

 soils. The main trouble in these latter cases seems to have been the 

 encroachment of the sod, resulting in a much lower catch and slower 

 growth in the early years. As a result of our experience, the present 

 practice is to use 2-2 stock with white pine, Norway spruce, and 

 Douglas fir and 1-2 stock with Norway, Scotch, and western yellow 

 pines. Unfortunately, the parallel plantings made with different ages 

 of stock of the same species were placed upon privately owned lands 

 and were allowed to run for a short time only. One case will illustrate 

 the general trend of results obtained. Two plantings of white pine 

 were established side by side on level ground with all conditions the 

 same, except that one was started as 2-0 stock and the other as 2-2. 

 At the end of two years, the 2-0 stock showed a catch of 52 per cent, 

 the other 95 per cent ; the average height of the 2-0 stock was five inches, 

 of the other 18 inches. 



All hardwoods have been started as one-year seedlings, except cotton- 

 wood, which was established by cuttings. 



Spacings used have been 3x3. 2x4, 4>^x4>4, 5x5, 6x6, 7J/^x7i/2, 

 10x10. The 2x4 spacing was used only in seed-spot work; the 10x10 

 only with cottonwood. In a few cases parallel plantings have been made 

 with the same species, using two or three difl'erent spacings. The 

 results of these are already instructive. 



Three areas of black locust were set in lOOG with spacings of 3x3, 

 4^x4^ and 6x6. Measurement of all the trees on these plots last 

 year showed the growth to have been as follows : 



These figures represent the growth during 14 years after planting.
