but dry, underfoot and overhead, and by the time Calder Farm 
was reached the members were in need of a good fire to dry 
their garments. After a rough-and-ready lunch some of tlie party 
went with the conveyances to Ingram, but the major portion 
took a traverse over the moors to see a fine series of overflow 
valleys which were caused by the advance of a glacier into the 
Breamish watershed. A porphyrite full of quartz amygdules was 
found on the nortliern side of the valley above the footbridge. 
On Tuesday morning a visit was paid to Chillingham Park 
to see the herd of wild white cattle. This famous herd, which 
numbers about fifty, was well seen, and lunch was partaken of 
in the park summer-house. On the return journey the party 
alighted at Akeld, and ascended the moors to the south of the 
highroad to examine some glacial overflow valleys. A series of 
these dry valleys was examined continuing across three spurs, 
and exhibiting evidences of cutting by considerable volumes of 
water. These valleys are wide and open at both ends, cut 
across the lines of ordinary drainage ; all dip in the same direc- 
tion (southward), and are related to one another just as a series 
of overflows would be from a succession of lakes held up by an 
ice-sheet which closed all the easterly valley mouths. In ex- 
amining the drift of Calder Farm and Akeld abundant boulders 
of a gre3"-green quartzose greywacke sandstone were found, 
boulders of which are also frequently found in the drifts of the 
Yorkshire coast. This was an important identification, as the 
locality of the rock had not been previously known by Yorkshire 
geologists, and, though not found in situ, the numbers in which 
it is found as a constituent of the Cheviot morainic gravels gives 
the direction of its source. 
Before the party separated a specially enthusiastic vote of 
thanks was accorded to Mr. Percy F. Kendall, F.G.S., for the 
way in which he had put his geological knowledge and experience 
at the full disposal of the members, and done so much to render 
the meeting a thorough success. With the exception of Monday 
morning's thunderstorm the weather was hot and clear, and the 
excursion was most enjoyable and instructive.
