LEVENSHULME LIMESTONE. 129 



nently placed so as to be accessible for examination. They 

 present many points of great interest in addition to the 

 fossils which they contain in plenty. Some large blocks, 

 over a ton in weight, have weathered and worn surfaces, 

 bearing evidences of having formed the outcrop for some 

 time before they were covered up by the boulder-drift. 

 Mr. Boyd Dawkins saw some of them in situ whilst the 

 drift was in progress, and he informed me that the appear- 

 ance was like that of the creviced top of a limestone hill 

 in the Craven district ; and some of these blocks have quite 

 this appearance, being coated with carbonate of lime on 

 several sides. There are some which appear to have formed 

 a floor, having been planed down to an even surface, showing 

 the veins of crystal very distinctly, as in a marble chimney- 

 piece. And one large block of a ton weight bears unmis- 

 takable evidences of glacial action, having well-marked 

 striae and a polished surface. These particulars have been 

 pointed out to several geologists who have inspected the 

 blocks, and may be taken to be accepted facts. I think, 

 therefore, we may safely say that the Levenshulme lime- 

 stone formed an outcrop-ridge for some time subject to 

 atmospheric influences before it was covered up by the 

 Boulder-clay, that it bears evidence of glacial action, thus 

 showing the agency by which it was altered to its present 

 aspect and finally entombed. 



Passing eastwards from Slade Lane, it has already been 

 stated that the Boulder- clay was found to exist to a con- 

 siderable depth, as shown by Mr. Harper's section. I 

 have also ascertained from Mr. Worthington, the Engineer 

 of the L. & N. W. Railway, that in the deep foundations 

 for the bridges just erected in widening the railway at 

 Levenshulme, no rock has been found, although it was 

 sought for to a considerable depth. I have also made in- 

 quiry in the village, and cannot learn of any case from
