November is the month when production of the B.B. is normally at its lowest ebb.  Preparations for the Christmas B.B. are usually under way and the November issue is something which gets in the way of this effort. However, this month's issue deserves a few comments as it is the first to be distributed under the latest postal system - for the benefit of those receiving it by post, it is due to be given out in Bristol on Thursday, November 7th.

We regret that there has not been time for Stalagmite's usual comments on the Mendip scene, but welcome instead a climbing article.  The new batch of covers have also arrived.  That would seem to be all until the Christmas edition next month.

Climbing

(North Wales - 26/28th October.)

After a period of inactivity, the Climbing Section bestirred itself sufficiently to have a weekend in North Wales.  The venue was Llanberis and the accommodation was arranged by Tony Dunn, with most of the party staying at the London Mountaineering Club hut.

Saturday morning saw the main walking contingent, comprising of Alan Sandall, Norman Petty, Jim Pembury and Ron Bater pounding round the Snowdon Horseshoe.  This trip was enlivened by some original route finding by Alan.  Some of the party nearly succumbed to the much feared 'Mountaineering Lassitude' caused, it is believed, by walking uphill.  Other causes were suggested.  Meanwhile two climbing parties - Mo Marriott, Kangy King and Brian Reynolds on one rope with Tony Dunn and John Howliston on the other, ascended Avalanche on Lliwedd.  They intended to finish in the Approved Fashion by doing Red Wall, but this was seething with bods, so the second half of Great Chimney was taken instead.  This was finished off by doing the Snowdon Horseshoe in the reverse direction to the route taken by Alan Sandall et al.

The rest of the party assembled in the Ogwen Valley where Lionel Williams and Nora went round the Glyders, having failed to rendezvous with the Bennetts at the foot of some obscure cliff on Foel Goch.  Roy and Joan Bennett completed some vague climb on the aforementioned obscure cliff, and returned from the top of Foel Goch by the not to be recommended North Ridge. The Attwood family were also in the Ogwen Valley and were walking on Y Garn.

The weather on Sunday was unexpectedly good for North Wales in October, and some members even complained of the heat.  Messrs Reynolds, King, Dunn and Howliston walked over Glydr Fawr and Foel Goch from Llanberis.  Lionel and Nora walked on Snowdon while the rest of the assembled company headed for the Carnedds.  The dreaded 'Mountaineering Lassitude' struck once more, and this time several of the party succumbed and had to be abandoned.  Steve Tuck and Roy Bennett drooped off to do amphitheatre Buttress, while the rest of the party forged ahead to ascend Carnedd Llewellyn.  Some even reached Carnedd Dafyd before returning to base.   All bodies being recovered from the mountain, most members headed for home. Jim Pembury and Brian Reynolds stayed over the Sunday night, and ascended the Glyders independently on the Monday.

A most successful and enjoyable weekend.

Social Column

We have included this article in place of 'Stalagmite' as he has hot been able to contribute.  Incidentally, there seems to be an ominous silence about the B.E.C. Dinner this year!??

by Jill Rollason.

The Dinner of that other club, followed by Hywel Murrel's party at "Calamine", went off in fine style on Saturday 19th of October and the B.E.C. was well represented.  A very enjoyable time was had by all, even those (especially those?) who turned green towards the early morning.  The guests partook of turkey and a full tray of twenty peach melbas and ice cream was dropped by a waitress in the vicinity of Mr. David Perry, whose suit suffered somewhat.

Cox's Cave was open to the guests after the dinner, and the intrepid Mr. 'Dan' Hasell upheld the caving tradition of the B.E.C. by undertaking the full trip through this perilous cavern.  The party then continued with great liveliness at Hywel's where the squeeze machine proved very popular.  The record was 6.25", though several others managed to get through 6.5.  Many of the activities took place to the accompaniment of shrieks as ice cubes were brought in and surreptitiously dropped down the back of anyone unwise enough to leave themselves unguarded.  An interesting game was seen where a couple were trapped together under a blanket and told that they had to take off an unnamed article, although unsuccessful in finding out what it was (actually the blanket!) they did their best and produced a variety of unwanted items of clothing.

The breaking up of the party at about 3.30 am found many of the participants a little uncertain of their whereabouts.  Mr. Ponynting found the ground rather unstable, lost his balance and "bottomed" the Hillgrove track at one stage when it lurched more violently than usual.  The party spirit had not disappeared next lunchtime outside the Hunters when some climbing techniques were demonstrated, altogether a very entertaining time.

Brixham Bone Cave or Cavern (S.C.)

Due to my working in this area, and to the Editor's plea for more material, I found myself with the "missus" paying one and sixpence to see the wonders of Brixham Cavern (page 233 in Britain Underground - Windmill Hill Cave.)

It was discovered in 1858 by some workmen - probably leaning on their shovels too hard - digging the foundations for houses that were to be built for a Mr. Philip.  The cavern is entered through a door beneath the house and is located where the cellar might have been.

Throughout this system there are definite signs of its having been encouraged by vast water activities at some early stage in its life.  Since its discovery, it has been exhaustively dug by the Geological Society and has provided masses of archaeological material.  Most of the discoveries are on view in the London Natural History Museum.

 

According to the guide pamphlet, one of the large stalagmites is estimated to be over 200,000 years old, but the most important discovery was that of the existence of man in the form of a few bones and flints etc., in the same layers as that of bones of long extinct animals, thus proving fairly conclusively that man was contemporary with the animals in question.

(There are four main sections to the cave.  In the Reindeer Gallery the remains of reindeer can be seen still embedded in the stalagmite floor, along with that of cave bear and hyena.  Off this, as an extension, runs the Crystal Gorge, where bone remains of the cave lion and mammoth were found.  The mammoth remains are considered to have been washed in by the vast amount of water which followed the glacial period.  We next come to Flint Knife Gallery where, in addition to flint knives, scrapers and more remains of cave bear, hyena and cave lion were found.

In West Chamber there are several showcases of bones and photographs, displaying the varied species of bone remains.  A notice states that the minimum age of these specimens is 20,000 years.  Finally, South Chamber contain a few formations which are small in keeping with the general size of the cave.

That, to the best of my knowledge, is it.  Not being much of a chronicler, you will have to excuse by bad style but I hope this short write up will suffice to help fill in another small gap for those who are interested in oddities of caving information.

An Echo Sounding Bird.

In the year 1800, a German Scientist, Alexander von Humboldt, described a remarkable cave dwelling bird found in South America.  The bird is called the Guacharo (Spanish for 'one who cries and laments') and Humboldt visited the great cavern of the Guacharos near the town of Caripe in the highlands of Venezuela.

He reported the bird to be the size of a chicken with a wing span of three and a half feet, an extremely strong beak, and blue eyes dazzled by the daylight.  The bird is covered with extensive deposits of fat and is much prized for its oil - a transparent, odourless butter-like food that was said to keep for a year without becoming rancid.  Once a year, the Indians went into the cave with long poles and knocked down the nests from the high roof, killing several thousands of nestlings. Today the bird is government protected.

One of the most remarkable attributes of the Guacharo is its powerful voice.  Humboldt wrote “It is difficult to convey any idea of the frightful noise which thousands of these birds produce in the dark portions of the cave."  In 1953; an American team led by Prof. Griffin from Harvard went to the cavern to investigate the possibility that the bird used its cries in a similar manner to the bat.  Firstly it was established that the birds did, in fact, live in complete darkness during the day and fly out of the cave at night in order to feed.  The next problem was to find out whether the birds used the squawks and shrieks for orientation.  Some of the sounds uttered by the Guacheros were rather sharp, short, clicks but they only formed a small part of the total noise.  Accordingly a microphone, together with an oscillograph and suitable recording devices were set up to record the flight of the birds at twilight.  To the surprise of the party, there were no shrieks or squawks but instead a steady stream of very sharp clicks, each click had a duration of only one or two thousandths of a second - about the same length as the ultrasonic signal of bats.

By catching some birds and taking them to a dark room, it was shown that they do, in fact, use the clicks as a means of object location when flying in the dark and use ordinary vision in the light.  The birds sounds have a frequency of about 7 thousand cycles per second (7 kc/s) and their wavelength (about 5 cm) compared with that of a bat's ultrasonic sounds (about 1 cm) indicates that the bird could probably not detect objects as small as those which a bat would detect with ease.

The Guachero is another case of echo sounding in nature.  I wonder how a Mendip caver would feel if suddenly confronted by such a bird on entering a cave at twilight?
