PLAT 3. 



This plat consists of European larch and box elders, planted 

 alternately throughout the plat. Larch trees 6 to 8 inches high 

 were bought and ^rown in nursery rows one year, then trans- 

 planted in the plat. Yearling box elders were used, except a 

 few two-year-olds. As will be seen by referring to our Bul- 

 letin No. 20, many larch trees were killed by a late storm in 

 May 1890. The survivors have shown peculiarities in growth 

 that are of interest. Only a very few of the trees have devel- 

 oped a leading branch, and made strong upward growth. Al- 

 most all have made good growth of latral branches, which are 

 horizontal and near the ground. The few that have begun ver- 

 tical growth, first made a similar latral development, so that it 

 is probable the remaining ones will develop "leaders" during 

 the next few seasons. The plat is the poorest in the plantation, 

 both in the number and condition of its trees. The larch 

 have grown slowly, and at the first a good stand of box elders 

 was not secured, so that there has been nothing to catch the 

 snow, and the ground has been bare during the winters- In the 

 summer the slight shade has not been sufficient to keep down 

 weed growth, and though the plat was cultivated two times 

 more than the remaining ones of the planting of '89, it now con- 

 tains the most weeds. The principal weed is Setaria viridis, 

 fox tail grass; the wild licorice, Glycyrrhiza lepidota, and wild 

 rose, Rosa hlanda var. Arkansana, weeds with very tough un- 

 derground stems, are more common in this plat than in any 

 other. They are extremely difficult to exterminate, nothing but
