210 JOWETT AND MUFF : GLACIATION OF BRADFORD, ETC. 
(4) In a quarry on the north side of Crag Lane, Windhill 
Crag End, Shipley, well-marked parallel striae run from N. 35° W. 
to S. 35° E. The larger pebbles of quartz are covered with 
numerous close-set and fine scratches. The north end of each 
pebble is rounded and scratched, but the south end is left rough. 
Some of the pebbles, when hammered out, were found to have 
been so worn down that they were represented only by a thin 
lens of quartz. 
(5) In the quarry between Midgeley Wood and Baildon 
Green, to the north of Shipley, the top of a thick substratum 
of gannister is of a montonnee character, well smoothed, and 
with well-marked though not very numerous striae.* Three 
observations taken at distances of about ten yards apart gave 
for their direction, (1) from N. 90° W., (2) from N. 80° W., 
(3) from N. 77° W. The gannister is covered by a bed of clayey 
gravel up to four feet in thickness, which is in turn overlaid by 
10-15 feet of yellowish boulder-clay. 
(6) In the recent excavations west of Apperley Bridge 
Station, the top of the grit in the cutting was found to be striated 
from N. 25° W. to S. 25° E. Knobs of rock projected above 
the general level of the surface, and round these the striae were 
deflected as much as 30°. On two large undisturbed boulders 
in the gravelly clay with limestone which covered the striated 
surface, scratches were observed running from N. 25° W. to 
S. 25° E. 
(7) The floor of the pit opened within the enclosure of the 
Weecher Reservoir, near Fawcather, is composed of ferruginous 
sandstone, which is striated from N. 55° W. to S. 55° E. The 
striae are numerous, and may be seen covering many square 
yards of the floor of the pit. They are also exposed in the bed 
of a small stream a httle to the west. The surface is slightly 
uneven, and it is the north-west sides of the prominences which 
are striated. The scratches can be traced under the yellowish 
boulder-clay, which is about eight feet thick, and contains 
rounded and subangular boulders of sandstone, grit, gannister, 
and limestone.
