NOTES ON TWO BORINGS. 
The object of the following paper is to preserve a record of 
two borings made in the neighbourhood of York. 
The first of these borings was made at Strensall, the object 
being to supply Strensall camp with water. It was stopped on 
Eeb. 9th, 1884, at a depth of 1180 feet, the water, though the 
supply was abundant, having proved useless for drinking* 
purposes. Specimens of the boring cores w'ere, through the 
kindness of Colonel Walker, presented to the Yorkshire 
Philosophical Society; the}" are now deposited in the Museum. 
I must also liere express my obligation to Col. Turner, through 
whose kindness I w^as enabled to compare our specimens with 
the engineer’s plan of the boring. 
The second boring was made in 1891 on the premises of Mr. 
Joseph Rowntree’s Cocoa Works on the Haxby Road. This 
boring was made to obtain water for use on the works and 
was carried to a depth of 233 feet. An abundant supply of 
excellent water was obtained. Mr. Rowntree kindly presented 
specimens of the cores to this Society and supplied the data 
given below from the engineer’s 
plan of the boring.
