Fig. 7, called the Lady's Chair, is from a photographic sketch, 

 looking eastward up the slope from the west side of the Causeway. It 

 shows the articulations of the joints, both vertical and horizontal; 

 some of the latter convex and some concave. The points called spurs 

 referred to in the last paragraph, are seen broken off in several of the 

 blocks. Half an inch from the base, near the left hand corner, some 

 water is seen in a black spot of oval form, resting in the hollow of one 

 of the columns. Visitors can walk over this slope with facility.

Balsaltic Columns, at the Giant's Causeway, called " The Lady's Chair." 



At the south end of the Causeway is a whin dyke, about 10 feet wide, 

 which cuts through the Causeway itself. This dyke has had the effect of 

 elevating the columns which come in contact with it on the west side, 

 so that the present position of the columns shows the sloping outwards, 

 at an angle of about 110°. The guides call this group the Giant's Artil- 

 lery, or the Giant's Cannon. It is worthy of remark, that the columns 

 are as complete as any others about the Causeway, and that they must 

 have been hardened and crystallized before the intrusion of the melted 

 matter of the dyke. 



The eastern facade of the Causeway is called the Giant's Loom, and 

 the longest column in the loom is 34 feet. Some of them have 38 

 joints visible. The base of the layer at the loom is not visible at low 

 water. As it rises, however, in the cliff to the east, it is seen in its 

 continuation to rest on red ochre. 



In the Giant's Organ, a noble facade, which is situated at the east 

 side of Port Noffer, the bay next east of the Causeway, the longest 

 column is 42 feet ; but the red ochre on which it lies is not visible
