red Calciferous sandstones, from their close resemblance to those 
about Wemyss Bay. If such be the case, we have here 
evidences of a very extensive displacement having taken place 
_the dark-red sandstones and conglomerates have undergone 
little change, but the calciferous sandstones and shales on the 
north side of the dyke have been extensively faulted down, in all 
likelihood during the time of volcanic activity, of which this trap- 
dyke and others in the neighbourhood are the mementoes. 
Time will not permit me to say more at present, but if what 
I have said leads to more interest being taken in the rocks 
along our coast line my purpose shall have been served. I may, 
however, explain that since I set myself to, write these few 
notes a great many things have had to be attended to which 
curtailed my little leisure, with the result that I have been able to 
touch only on a few of the more salient points connected with 
the geology of this part of Clydesdale.
