you bend with it you pass a goodly cluster of tulip 

 trees, tall and fair and straight, with leaves cut rather 

 squarely at the tops, and beautiful tulip-like flowers 

 in late May or early June. These flowers are very 

 handsome, large and challice-shaped, greenish yellow, 

 strongly marked about the base with yellow. The 

 cup-shaped corolla is of six petals. These handsome 

 flowers are succeeded by light brown "cones," which 

 remain on the tree late in winter, showing conspicu-

 They are sure signs of the tree's identity. In the 

 autumn the tulip tree is a glory. Its leaves turn a 

 rich brilliant chrome yellow. 



The Walk carries us over the Bridge and, just be- 

 yond, it forks right and left. Directly in the branch 

 of the fork is Austrian pine. Taking the left branch, 

 we go westward a little and step out on the large rock 

 which fronts the Ball Ground like a buttress. As we 

 stand overlooking the Ball Ground, almost within reach 

 of our hand, a few feet to the right of the rock on 

 which we stand, is a lusty young shagbark hickory 

 with five leaflets and a bark mostly smooth, but be- 

 ginning to shag in places. Note the buds with their 

 distinctively strong outer scales, the sure mark of the 

 shagbark in winter. Following the path along, it 

 bends to the northward, tumbles down between rock 

 masses, and swings out upon the Ball Ground itself. 

 Just as it opens out upon the main Walk here, it 

 leads us by a tall old scarlet oak almost in the corner 

 of the junction of the two paths. Here we take the 

 Walk which runs about the Ball Ground like a girdle,
