The walls of these are cracking in many places, and give 

 signs of such weakness, that 'ere long, some of the details 

 which to-day we examine with so much interest, may be 

 numbered amongst the things of the past." 



The next object of interest, was the Parish Church of Bever- 

 stone, over which the visitors were conducted by the Curate, 

 the Eev. W. H. Kemm. The Norman work and some old 

 inscriptions were examined, and a parish register dating from 

 1565 was pointed out as an object of curiosity. 



Leaving Beverstone, the Club visited the quarries near 

 Chavenage, and the Great Oolite with its subdivisions of Brad- 

 ford Clay and Forest Marble were pointed out by Mr. Witchell, 

 who drew attention to the great benefit the district derives 

 from the beds of Bradford Clay. These beds, three in number, 

 and each about a foot in thickness, are the water-bearing 

 straia throughout the district, and but for them no ponds or 

 pools could be maintained except at a great expense, and no 

 water could be obtained except from wells 80 or 100 feet deep, 

 and sunk in the solid rock. The " shelly beds" of Minchin- 

 hampton are here represented by a single bed, and the "white 

 limestone beds " of Bussage and Sapperton have thinned out 

 and are altogether wanting. 



After Dinner at the White Hart, Tetbury, Professor Chttech 

 called attention to some experiments he had made with the 

 clays of the " Forest Marble," and he regarded the Bradford 

 Clay, as similar in character. He found that the percentage 

 of Carbonate of Lime in the Clay was greater than in the Forest 

 Marble. He then refen-ed to the clays found in the fissures 

 of the rocks in the district, upon which he had likewise experi- 

 mented, and the result showed that these clays differed entirely 

 from all other clays in the district. 



Mr. WiTCHELL was of opinion that the clays found in the 

 fissures were formed of glacial mud, and he mentioned having 

 discovered in it small pieces of iron, quartz and other pebbles, 

 and some small pieces of Mammoth bone. 



Further experiments were promised by Professor Church, 

 the results of which will be communicated to the Club.
