been sunk for the reception of it. The water issues from the shales 
below the Millstone Grit in a piece of highly disturbed bedding — 
the first shales discoverable on the N.W. side of the anticlinal axis 
on the north side of Harlow Hill. A great fault is believed to run 
through this spot for several miles to the S.W. and N.E. 
One mile nearly due S. of Harlow Car is Low House, Beckwith^ 
near which in a small stream which joins Crimple Beck, you will 
find some thinly bedded hard sandstone (the Yoredale grit, well 
exposed in the quarry on the road close by) dipping at a very high 
angle, and forming an anticlinal axis. At this point a sulphur water f 
flows into the side of the brook, where the strike of the bedding 
suddenly turns from E.N.E. to almost due N. in the direction of 
Harlow Car. This sharp turn of the anticlinal axis is interesting in 
respect to the issue of sulphur water through the highly disturbed 
bedding of the sandstone. 
Numerous small jets of sulphur water are also readily detected 
issuing from the Yoredale shales seen in the bed of Crimple beck? 
about a quarter of a mile to the south of Low House. 
The chemical composition of the Beckwith Sulphur water is 
essentially that of the Harlow Car issues : the sulphide in both being 
associated with a good proportion of alkaline carbonates, and with a 
small amount of chlorides. They also resemble the Bilton and 
Starbeck issues to the east of Harrogate, in containing alkaline car- 
bonates — salts which are not found in the strong saline waters of 
Harrogate. J 
2. — The Bolton Woods Sulphur Spring. 
The highly crumpled district of Bolton Bridge, 13 miles to the 
west of Harrogate, also provides a sulphur water which flows in 
Bolton Woods from the Yoredale shales. The association of this 
t Some few years ago I isolated this water by digging down to the shales 
through which it rises, and by fixing a drainage pot. This issue is now, however, 
silted up with sand ; but the sulphur water has since broken through the lamin- 
ated and highly ferruginous sandstone on the opposite side of the stream, and has 
there abundantly precipitated the iron as black sulphide, and has besides left 
whitish streaks of uncombined sulphur. 
X This statement is not invalidated by the fact that Mr. Hayton Davis 
has lately found alkaline carbonates in some mild sulphur waters near the 
Victoria Baths, and in the Crescent well : for these are not representatives of the 
strong saline issues.
