Horsury. Morainic Ridge. 
About half a mile down the valley from Broad Cut, from which 
point the river runs a little over a mile nearly due east, on the right 
natural bank, a low ridge, or a slight elevation of the ground 
commences, which leaves the river at an angle of about 45° and 
runs south-east for about a mile, when the land slopes down to the 
level of the valley, which at this place is a broad plain (80-100 ft. alt.), 
bounded on the south and south-east by high land (100-225 ft. alt.), 
in the form of a quarter of a circle, or rather an oval formed by the 
slopes of Sandal Castle and Milnthorpe. The ridge does not 
continue over this low land, but spreads out over the south side in 
afan-shape. ‘This ridge with its fan-shaped termination is composed 
of clay largely mixed with boulders from the size of a walnut to that 
of a cricket ball, ferruginous sand and fine gravel. There are a few 
boulders a foot in diameter. I have found granites. The ridge is 
from 300 to 400 yards wide, about 4 ft. thick in the middle, and 
thins out on both sides.

MILLWoop. 
An excavation for a gasometer tank at Millwood, Todmorden, 
cut through a bed of glacial drift of considerable thickness, which 
contains large quantities of foreign boulders, all more or less 
rounded, as well as the local stones with which they are associated, 
and varying in size from that of an egg to blocks weighing three- 
quarters of aton. Some of the foreign stones have one or more flat 
sides, showing them to have been subjected to glacial action for 
a considerable time; they are well polished and very finely striated, 
the striz running the longer axis of each stone. This deposit of 
gravel and boulders, situated on the north side of the Calder, and 
some 15 ft. above its bed, is about 17 ft. thick. It is thickest to the 
north, and thins out towards the south where the Yoredale shales dip 
into the hill. The proportion of foreign stones to that of local is 
about eight per cent., and there is no sign of stratification in the 
deposit. ‘The interspaces between the boulders are filled in with 
mud and gravel. A very local patch of tough blue clay containing 
boulders was cut through in one part of the excavation. It had 
a resemblance to boulder clay, and was about 2 ft. thick. It 
occurred at the base of the cliff and rested on the decomposed 
Yoredale shale. Some of the larger boulders have been removed to 
the grounds of Mr. Wm. Ormerod, Todmorden. The following
