22 CONSERVATIVE LUMBERING AT SEWANEE, TENN. 



Slope and Lower Slope, where it reaches a diameter of 30 inches. It 

 requires good soil. Sugar Maple bears abundant seed every few years, 

 and the slopes below the old trees are thickly covered with seedlings, 

 which thrive in the deepest shade. The eagerness with which cattle 

 devour the seedlings limits the reproduction of the species. 



Red Mapli is confined to moist Bottom, where it associates with 

 Black Gum and White Oak. It is usually very crooked and has a low, 

 forking crown. One unusually large tree measured 27 inches in diam- 

 eter. The average size is about 8 inches. Seed is plentiful every two 

 years, and a good part of it germinates where the ground is so wet 

 that lire can not burn. In drier Bottom the reproduction is wholly 

 from sprouts, which are sometimes so abundant as to form thickets. 

 Bed Maple is very sensitive to lire. 



Yelloxo Buckeye is found only in the coves, where, on the benches 

 of Northerly Slope, it forms a large, full-crowned tree, with an aver- 

 age diameter of 18 inches and a maximum of 38 inches. It occurs 

 also on Lower Slope, where it is of poor quality. Buckeye bears seed 

 about once in three years. The seedling reproduction is usually good. 



White Basswood is scattered over Northerly Slope. It grows rather 

 tall, and has a large, tapering crown. The larger . trees are usually 

 hollow. The average diameter was 17 inches, the maximum 37 inches. 

 White Basswood seeds about once in two years. Although it is 

 tolerant of shade and sprouts freely, its reproduction is poor. It is 

 sensitive to fire and is much harmed by the browsing of cattle. Borers 

 attack the wood. 



[Flowering] Dogwood is common on Northerly Slope in the coves, 

 but is found sparingly on the plateau, where it is limited to Oak Flat. 

 In both situations it forms a short, crooked trunk and a flat crown. 

 The largest Dogwood found measured 17 inches in diameter. The tree 

 bears fruit almost every year, and reproduces well in deep shade. 



Blue Dogwood occurs with [Flowering] Dogwood on the benches of 

 Northerly Slope, but is not nearly so abundant as the latter. No 

 specimen was seen over 4 inches in diameter. 



Black Gum grows in all situations and soils at Sewanee, but makes 

 its best growth in the rich, moist soils ®f Bottom, where specimens 

 30 inches in diameter may be found. Black Gum seeds freely every 

 year, and its seedlings form a considerable part of the forest repro- 

 duction. Young growth of varying ages may be found wherever there 

 is a large Black Gum to scatter its seed. When well started, the 

 seedlings will bear a great deal of shade, and they have such dense 

 crowns that they shade out other species. Fire ha> hollowed out the 

 butts of many of the trees, but Black Gum seldom dies until blown 

 over. 



Soxirviood is common to the plateau. The largest trees are in Bot- 

 tom and far clown on Hickory Slope. Most of the growth consists of 

 bushy sprouts. Occasionally a tree attains a diameter of 11 inches.
