bable that they are due to the withdrawal of rock-salt which has 

 been going on there of" late years only. In this case the depth at 

 which the cavities are being formed and rock-collapses are, as I 

 believe, taking place, is much greater than in the Sunderland case, 

 the borings for salt being from 1000 to 1200 feet deep. 



I will conclude with a quotation from my paper on the Breccia- 

 gashes,^ p. 174: — "The forms of these gashes, which are gullet- 

 shaped and tapering downwards, unlike the sea-caves ; the breccia 

 with which they are filled ; the matter with which the fragments 

 are cemented ; the half-broken beds which so often bridge over the 

 upper portions of the fissures ; and the unbroken beds immediately 

 above and below them, which would be inconceivable had the 

 fissures and their infillings been due to real earthquakes. All these 

 things are necessary accompaniments of the rock-collapses which, it 

 has been shown, must in time past have happened frequently, are 

 happening still, and must happen more and more frequently in the 

 future."
