HAWKESWORTH : SOME DRIFT DEPOSITS NEAR LEEDS. 457 
Messrs. Jowett and Muff* mention yellow boulder-clay, 
10 feet thick, with boulders of ganister. encrinital chert, and 
striated Millstone Grit, at Roth well Haigh. Mr. Muff informed 
the writer this was exposed in making* drains, and its relation- 
ship to the gravels was not noted. 
Present Sections. 
Bothivell Haigh patch. — Xear the westerly edge an excava- 
tion was made in 1904 for a storage reservoir, above the 250-foot 
contour-line (see A on map). It exposed about 10 feet of 
varying sand and gravel, of yellowish colour, with intercalated 
beds of large stones, current -bedded in places, with traces of 
contortion in one place. Towards the upper part, especially 
at the northern end, the material became more clayey. Rock 
was not reached here, but other temx3orar\' excavations in the 
neighbourliood prove a thickness of quite 30 feet of similar 
material. 
About 150 yards south-east of the previous section (see B 
on map) is a sandpit showing from 10 to 15 feet of yellowish 
sand and grav^el. but the number and size of the contained 
stones is not so large as at the reservoir, though they are so 
plentiful that all the sand has to be screened. To show the 
extreme variability of these dejDOsits, this pit is now being 
w^orked in a westerly direction, exposing the following section : — 
Very coarse gravel . . . . 2-3 feet 
Sand, evenly bedded, practically 
free from stones . . . . . . about 10 feet 
Gravel . . . . . . . . .. 1 foot 
Large boulders resting on rock . . .. 1 foot 
In the sand are distinct incursions of rough, clean, angular 
white quartz grains, reminding one of broken-up coarse Mill- 
stone Grit, evidently not water transported for any considerable 
distance or time. 
The finest and most interesting section in this patch is 
found in a large sand pit nearly opposite the John o' Gaunt Inn,
