AND U. S. EXPERIMENT STATION. 11 



The month of July brought with it many seasonable showers, and 

 these, with the warmer weather, enabled the trees to make a good start. 

 The last cultivation was given during the week ending July 27th; after 

 that date the barn grass and tall growing weeds were kept down with 

 hoes. 



THE SEEDLING FOREST PLAT. 



This plantation, covering two acres 49 rods, was planted with tree 

 seeds in the fall of 1887. The method of planting, and growth during 

 1888, has been described in Bulletin No. 12. In April all the vacant 

 places were set with one and two year old trees of the following varie- 

 ties: Box elder, cottonwood, Norway poplar, laurel leaved willow, 

 white birch, yellow birch, Scotch pine, white pine, white ash, white 

 elm. On June 14th all the tips of the lateral branches of the trees 

 which had come from the seed planting were pinched back, leaving 

 only one leader; the effect was to increase the growth of the leading 

 branch. 



In the following table the letter T after the name of a variety in- 

 dicates that it has been set in the plantation the present year. All 

 other varieties are of the original planting of seed in the fall of '87, 

 and hence the measurement of the two years' growth is given. It has 

 been interesting to observe the growth of the transplanted trees com- 

 pared with those grown from the seed where they stand. Without ex- 

 ception, the seedlings are far in advance of the transplanted sorts. It 

 is equally apparent that the trees in the forestry plats, for which the 

 ground was deeply plowed before planting, have grown better, as a 

 rule, than those set among the seedlings where plowing was impossi- 

 ble, though as thorough culture was given in one case as in the other.
