a rule, imperfectly drained, the greater part being as yet uncultivated. 
It is built on Permian strata, with hills of magnesian limestone rising 
close behind the village, and red Permian marls containing gypsum 
are found in the immediate neighbourhood. 
There are at present four wells, each with a pump room and 
suite of baths, and they are situate close to the western and south- 
western edges of the Pool, a comparatively shallow sheet of water, 
about six acres in extent, lying to the east of the high road between 
York and Doncaster, which runs through the village. 
The Manor Well Baths are on the eastern side of the Pool, in 
lat. 53° 36' 54" N., and long. l u 8' 55* W., but the water as actually 
used is supplied partly from the well at the south-west corner of the 
Pool, which also supplies the Charity Baths. This water is carried 
through the Pool in an iron pipe with flanged joints, and is allowed 
to mix, in a puddled well, with water derived from an old well that 
is under the building. 
The Terrace Baths are on the opposite side of the Pool, the well 
by which they are supplied being dug in the peat about 40 yards to 
the south of the Pump Room, between a row of dwelling-bouses and 
the edge of the Pool, in lat. 53° 36' 52 , 4 ,/ N., and long. 1° 9' 0" W. 
The well is constructed of brick with an outer lining of puddled 
clay, and the water is conveyed to the Pump Room through a lead 
pipe which has been in use for many years. 
The Charity Baths, near the south-west corner of the Pool, are 
supplied by a well which is about 40 yards distant from both the 
Pump Room and the Pool. This well is in the form of a large brick 
tank, built in the peat, with an outer casing of puddled clay. 
Although it is covered in it is doubtful whether the entrance of sur- 
face drainage is entirely prevented, and this fact detracts somewhat 
from the scientific interest of this water. 
The Town End or South Parade Baths are on the high road at 
the south end of the village, some little distance from the Pool. They 
are supplied by the Madder Close Well, the position of which is shown 
on the 6-inch Ordnance Survey Map. It is about 1 20 yards south 
of the Pump Room, in lat. 53° 36' IVf N., and long. 1° 9' I'd" W., 
and is simply a large tank cut in the peat, without any lining of
