brook which runs through it leading into the Esk, near Rus- 

 warp (i y 2 miles from Whitby). The ground rises close behind 

 the tree to a height of about no feet above the level of the 

 roots of the tree, which is about 40 feet high. On the other 

 side of the valley the ground also rises rapidly to about the 

 same height. The figure shows at C the space left free 

 by a band of the bark stripped off to a height of about 14 

 feet, which is the height at which the stem first divides. 

 An iron chain {b) is attached to one of the branches, and 

 supports a beam from which a swing is suspended. Large 

 splinters of the bark were thrown across the whole breadth 

 of the valley, i.e % about 60 feet, while others marked a in 

 the figure remained partly attached to the tree."
