HAWKESWORTH : SOME DRIFT DEPOSITS >'EAR LEEDS. 461 
Whinmoor (see G on map). — The Geological Survey noted 
that over the country to the north of Leeds, great masses of 
drift occur, consisting mainly of stiff blue clay, containing 
amongst others mentioned, trap, flesh-coloured granite, and 
chalk. A bore hole at Whinmoor went through 114 feet of this 
stoney clay.* 
Scholes. — Near here, in the cutting of the Leeds and 
Wetherby railway, between Scholes and Thorner, at over 350 
feet above O.D., is a section of drift, in which have been noted, 
amongst others, cherts and grits. 
At about same elevation, in Scholes, rounded boulders of 
very fine hard whitish sandstone were found in digging for 
foundations of a house (see I on map). 
Cock and Carr Becks. — In many parts of these valleys, 
and adjacent, pebbles of sandstone, grit, ganister, and chert 
are abundant. 
In other parts of this district traces of drift have been noted, 
as, for instance, in the fields north of Barnbow, about 300 feet 
above O.D. (see J on map), which are sprinkled with rounded 
pebbles of chert, sandstone, and ganister. At a higher eleva- 
tion still, west of Scarcroft (see K on map), in making pipe 
trenches similar pebbles, with limestone in addition, were found. 
Conclusion. 
With the present available information, the writer is in- 
disposed to generalise upon these observations, which are very 
detached, and somewhat obscure in some cases. The occurrence 
of real boulder-clay at Whinmoor and Rothwell Haigh seems to 
require further elucidation ; especially does the presence of 
igneous rocks at the former locality. 
It seems fairly certain that the Oulton and Rothwell Haigh 
deposits are not " river gravels of considerable antiquity," 
but these, taken in conjunction with the dispersal of pebbles 
and boulders very similar to those contained in them, between 
the Aire and the Wharfe, denote a period when the country be- 
tween the Wharfe and Calder (if not further north and south).
