112 GEOLOGY OF ARRAN. 



cent patronage of art and exquisite taste are well known. 

 His Grace, when yet in middle life, died at Paris, July 

 15, 1863. His memory will long be cherished, as is that of 

 the Duchess Anne, by the grateful islanders. 



57. Between Brodick pier and the gate of the principal 

 approach to the castle there are many curious dikes and 

 irregularities in the strata; indeed, the whole coast from 

 this point to Corrie is worthy of careful study, as illustrating 

 the natural history of dikes; and will prepare the geologist 

 to expect a broad dike to become a thread, and not to 

 be surprised if he see a dike "doubling" at an angle of 

 90 and " throwing" him completely " out." Between the 

 granite boulder and the gate there is one dike which is, 

 as usual, prismatic across, and breaking in westwards among 

 the strata becomes a bed parallel to them, and presents 

 on its upper surface a miniature "causeway" or pavement 

 of prisms of various forms, placed perpendicularly to the 

 surfaces of the bed. The case is very interesting, and 

 is a good illustration of the remarks made in Art. 52. A 

 little way east of this there are some other dikes on the 

 flat beach which change their directions in the most sudden 

 and puzzling way; and under the wall opposite the gate 

 a singular contrariety of dip in the beds; strata dipping W. 

 come "end on" against those dipping S. The dike here 

 which ranges due N. and S. by compass, and the others 

 already mentioned, may have something to do with this 

 irregularity. Near this point is the landing-place called 

 the wine-port, where in the jolly old times, when the 

 retainers were feasted in the castle, wine and beer were 

 brought ashore in hogsheads; and farther up, near the cliff, 

 are shewn the remains of an old burying-place, where some 

 important personages are said to have been interred. But 

 of this there is no special record. 



It would require a separate memoir on this coast to 

 detail all the curious particulars that might be mentioned. 

 We can only state in general that in the bay here are
