This is the First report of the new discovery in Stoke Lane Swallet. This will, I think, be one of the most important on Mendip for some considerable time. The report of the ‘Trap Divers’ will follow soon. _______________________________ STOKE LANE SWALLET By P.M. BROWNE Browne’s Passage An exploration party from Bruton, led by myself, made an important cave discovery in Stoke Lane Swallet, one of the least know caverns on Mendip. The members of the party were P.M. BROWNE, D. SAGE AND T.H. UMEACH. During the three hours of our exploration we had the luck to be the discoverers of a new and very interesting series of low tunnels and encrusted grottoes, totalling about 250 feet in length. This new system, now known as Brown’s Passage, doubles back upon the known cave and thereby introduces several very interesting hydrology problems, which I trust will be solved in the near future. Immediately after the discovery I arranged an expedition with the Club for the following Saturday. Accordingly the second party to enter the extension, consisting of D.A. COASE, R.A. SETTERINGTON and I, arrived at the little village of Stoke Lane at about 3.00pm on June 7th. During the preceding four days a considerable amount of rain had fallen on the surrounding land and so, on arriving at the cave mouth, we found the volume of water entering it to be far greater than it had been on the previous trip. In normal weather the entrance of the swallet is dry, or nearly so, but that day the water was thundering over the boulders and pouring into the narrow opening, and on into the darkness beyond. All being in readiness for the adventure I abandoned all thoughts of personal comfort for the following four hours and crawled into the uninviting gateway, to the strange world under the hills. Within a few seconds I was forming an admirable substitute for a leaky drain-pipe, with icy water pouring up the legs of my boiler suit and emerging by means of vents and other outlets somewhere above the knees. A sudden step enabled us to stand in a narrow keyhole shaped passage, in which the stream foamed and boiled around our feet. Suddenly the passage widened and lowered forcing us to crawl along an arch shaped tunnel of a type very characteristic of this cavern. On the floor the stream flowed through a series of muddy, leech infested pools. At about 30ft. from the entrance the roof rose slightly and we found ourselves on the brink of a large swiftly flowing stream, the main stream of the cavern, coming in from our right. Crawling in the water beneath a low arch we entered a long, narrow rift at the end of which was the first chamber. The murmuring river flowed through the chamber and vanished under a huge boulder at the far end. Looking back along the rift by which we entered this place we saw the lights from the rear of the party beautifully reflected from the surface of the rushing water. Now began the discomforts of the journey. Climbing over huge blocks of limestone we left the stream and struggled upward through a small and very muddy aperture to a steeply inclined bank of wet, glutinous mud. Below us, on the left, the stream again appeared from under a low arch. From here we had as it were the choice of two evils. One method was by following the water, the level which was just above one’s neck; and the other by what is known as the Muddy ox-bow. I enquired whether it was to be mud or water and the unanimous reply was mud please. At the top of the slope we literally slid through the door shaped opening which gave access to a small muddy grotto preceding one of the most uncomfortable portions of the whole cave. Those who have been through the Devil’s Elbow in G. B. Cave will be able to visualise a similar tunnel, entered through choice of two holes bored through a mass of solid mud, the floor covered by a pool of stagnant water. Dropping into the glue like mixture of mud and water I began to move forward, using my forearms as skids and my feet as barge poles. A sharp bend brought us to a long, narrow, and comparatively dry tunnel, at the far end of which I crossed the stream, which once again came rushing past from a large passage on my left, and turned to watch my companions wallowing through the mud-lined tunnel.
