part, and tapering at each end. The longer axis was nearly at right- 

 angles to the axis of the hill, lying south by west and_ north by east. 

 The section at right-angles to the one given in the diagram, Tig. 2, 

 and at a place near the centre of the patch, and nearly in the direc-

 it rested, having been broken off and pushed along bodily over the 

 undisturbed portion, in the direction of the valley, somewhat in the 

 manner indicated in the annexed figure. The hill is the spur
