Hills and their cappings of tracliytic rock examined. This 
igneous sheet was intruded into the Upper Old Red Sandstone 
rocks, and a quarry between tlie Mid and East Eildon shows 
one of the pipes, and pieces of altered marl are found caught in the 
igneous mass. In Mid Eildon specimens were obtained of a 
variety of the same rock containing riebeckite. To the north 
of the Eildons is a large mass of volcanic agglomerate filling the 
neck of an old volcano, and forming now a mass about a square 
mile in area. A similar neck was examined near Jedburgh, 
associated with extensive extrusions of dolerite. The Tweed 
below Melrose exposes in its banks some interesting glacial 
sections, and there is an old river valley, across the corner of 
the bend at Old Melrose, which is choked with drift. There is 
a ring of high-level gravels running round the sides of the valley 
from St. Boswell's to Galashiels, which probably mark the edges 
of a lake. Opportunity was taken to visit the renowned Abbeys 
of Melrose and Dryburgli, and all i)ronounced the field excursion 
to have been most pleasant and instructive, and it is hoped that 
it will lead to the identification of some rocks in the East York- 
shire drifts which have not hitherto been located. 
The Underground Waters' Committee has continued the 
investigation of the drainage of the slopes of Ingleborough in 
conjunction with the Committee appointed by the British 
Association. At the Belfast meeting the following report was 
presented to the Geological Section by Mr. A. R. Dwerryhouse. 
M.Sc, F.G.S. :— 
On referring to the last report of the Committee for the 
Investigation of the Underground Waters of Ingleborough it will 
be seen that on September 5th. 1901, three-quarters of a pound of 
fluorescein was put into the water flowing down Long Churn, 
near Alum Pot. at four p.m.. and that a further quantity of 
three-quarters of a pound was introduced at 5.30 p.m. on the 
same day. At the time of writing the last report the outflo\^' 
of this had not been observed ; but it has since been learned 
that it issued from Turn Dub, on the opposite side of the river 
Ribble, and close to the bank of that stream, on September
