what justifiable, that the party would see the place where the 

 water ought to fall. It appears that the stream, except when 

 very large, gets hidden among the boulders and debris that fill 

 its course, and that it finds its way to the sea by secret pas- 

 sages. Retracing our steps and resuming the journey, Glenarm 

 is reached a little before the appointed time, and a walk through 

 the park is indulged in, the day having to this point been dry, 

 though too heavy for distant views. After luncheon, the 

 remaining section of the road is accomplished in rain. Larne is

DONAGHADEE. 



The fourth excursion of the season was on 7th August, to 

 Donaghadee. Leaving the County Down Terminus at 1.15

 ducted to Coal-pit Bay, about a mile south of the harbour, 

 where there is exposed a series of black slates and shales, known 

 to geologists as a Graptolitic band. As announced by circular, 

 the principal feature of this excursion was to examine this 

 series. The locality is well known to many of the members as 

 by far the richest in our neighbourhood in these remarkable 

 fossil remains. The conductor announced that a prize would 

 be awarded to the member who, at the close of the day's work, 

 could show the greatest number of species. The leading geolo- 

 gical features of the spot were then pointed out. The black 

 shales and slates, almost vertical, appear in one of the many 

 anticlinal foldings of the Greywacke or Silurian rocks, the 

 axis of which seems to be a large dyke. Subsequent move- 

 ments of the strata have, however, greatly complicated the 

 beds, rendering it difficult to follow any particular zone. With 

 pinch-bar, picks and hammers, the party was soon busy raising
