Tests of Forest Trees.

The Red cedars have made growth nearly equal to stock set at the 

 same time in the nursery rows in very much better soil. The trees 

 in plat D have not been shaded as closely as those in plat B, and 

 show somewhat better growths, They are fine, vigorous trees. 



TABLE XV. RED CEDARS. 



Planted 1896. Measured November 1903. 



The Jack pine, Plnus divaricata, invoiced at the time of planting 

 as Plnus lanksiana, had not been previously planted here. While 

 not to be compared with the Scotch or Austrian pines as an orna- 

 mental tree, its present vigorous condition and its rate of growth make 

 it worthy of notice and mark it as of probable value for forest plant- 

 ings and windbreaks. Plate 12 (p. 131) shows this plantation. 



Table XVI gives a comparison of twenty-five successive trees of 

 each species growing in plat 1.12. 



Plat .45 was planted upon a gravelly southern slope, growing a, 

 heavy crop of grass, mainly bluestem. The holes were dug and the 

 trees were set in the sod. No cultivation has been given, but the 

 Scotch pines have made a surprisingly good growth for the condi- 

 tions. Considerable care has been required to maintain fire-guards, 

 as the grass has grown tall and rank. The Bull pine, P. ponder osa* 

 has not been so vigorous. 



Tables XVII and XVIII make the comparison.
