THE EBBING AND FLOWING WELL.

In the vicinity of Chapel-en-le-Frith is a steep hill, rising to the

hight of more than a hundred feet, immediately beneath which this

natural phenomenon lies. It is of an irregular form, but nearly

approaching to a square, from two or three feet in depth, and about

twenty feet in width.

Its ebbings and flowings are irregular, and dependent on the quantity of

rain which falls in the different seasons of the year; when it begins to

rise, the current can only be perceived by the slow movement of the

blades of grass, or other light bodies floating on the surface;

notwithstanding which, before the expiration of a minute, the water

issues with a gurgling noise, in considerable quantities, from several

small apertures on the south and west sides. The interval of time

between the ebbing and flowing is not always alike: consequently the

proportion of water it discharges at different periods, also varies. In

the space of five minutes flowing, the water occasionally rises to the

hight of six inches; and, after remaining a few seconds stationary, the

well assumes its former quiescent state.

The cause of the intermittent flowing of this well may be satisfactorily

explained, on the principle of the action of the siphon, and on the

supposition of a natural one communicating with a cavity in the hill,

where the water may be supposed to accumulate; but for the phenomenon of

its ebbing, no satisfactory reason has been assigned. The opinion of a

second siphon, (which is ingeniously advanced by one tourist,) that

begins to act when the water rises, is inconsistent with the appearance

of the well, and therefore can not be just.
