NOTES ON THE GEOLOGICAL RESULTS OF 

 THE EXCURSIONS. 



BY MR. A. COLLENETTE, F.C.S. 



Although I have been asked to speak of the results of the 

 excursions, presumably those organised and planned by the 

 Committee, I shall to-night consider myself free to include 

 many which have occurred and which were hurriedly organised 

 to investigate finds reported either by, or to, our members, for 

 these have a place in our summer's work. 



The excursions, although spoken of under the heading of 

 " Geological," will include some in which the interest was 

 more " Antiquarian " than geological. 



This year I have written under the following sub-heads : 

 («) Caves; (b) Rocks; (c) Superficial Deposits ; (d) Anti- 

 quities. 



Caves. 



I regret to say that the search for signs of occupation of 

 caves by prehistoric man has resulted in failure. 



The search was confined to two caves, that over the arch 

 at Les Tielles and the Dog's Cave (Creux an Chien). In 

 neither cave was it considered necessary to organise working 

 parties. The Tielles cave was difficult of access, but Mr. 

 H. Le Messurier and Mr. Tanner made the descent from the 

 cliff by means of ropes and succeeded in examining the cave 

 which, they reported, had a very shallow earth bottom which 

 gave no indication of man's occupation. 



A large party went down the cliff to the " Dog's Cave," 

 the work being made easy by ladders and ropes. The cave 

 was found to agree with the description already published.* 

 The search party consisted largely of our prominent members, 

 who gave no hope of the cave proving of value. 



Rocks. 



Owing to the interest attached to the statement made by 

 the Rev. E. Hill and Prof. Bonney, that the so-called horn- 

 blend schist of Pleinmont Point proved to be, under penolo- 

 gical microscopic examination, an altered shale, one of the 

 outings of the Society was organised (and was well attended) 

 to view the rock in situ.
