A BORING AT EAST HARLSEY. 
BY EDWIN HAWKESWORTH. 
{Read Uh March, 1909.) 
East Harlsey is a village about five miles N.E. of North- 
allerton, at the foot of the western escarpment of the Hambleton 
Hills. The bore-hole was put down with the intention of obtain- 
ing a supply of water for the hall and village, but was stopped 
at a depth of 350 feet* from the surface, owing to this object 
not being attained, though I have since been informed that 
some water is being yielded and used for outdoor purposes. 
The site is close to the church, between 300 and 350 feet above 
sea-level. As it is a little to the east of the assumed outcrop of 
the Rhaetic beds beneath the drift, it seemed likely to furnish 
valuable information as to the exact thickness of these rocks, 
but, through a most unfortunate chapter of accidents, exact 
measurements could not be obtained. However, such informa- 
tion as was obtainable may be worth putting on record. 
There is a bore-hole marked on the Geological Survey map, 
a few yards distant from this one, but it has not been possible 
to obtain details of the rocks passed through. Some of the 
old inhabitants of the village remember a boring being carried 
out many years ago, and the drillers went through two thick 
coal-seams !!! (Probably black shales.) 
The cores in the boring now described got so mixed up, 
particularly the upper ones, and the shales weathered so rapidly 
in the very severe weather prevailing at the time, that a fully 
detailed section cannot be made, but the following is approxi- 
mately correct : — 
Ft. In. 
1. — New soil, probably an old rubbish tip 2 9 
2. — Good paved road, with apparently an 
older road beneath . . . . . . 11 
3. — Hard shelly rock, variable in colour and 
texture, full of Gryphcea incurva 12 8 
4. — Dark shales, with several hard bands . . 113 6
