LEVENSHULME LIMESTONE. 127 



to Slade Lane ; it then turned southwards until a junction 

 was made in Slade Lane with the sewer ahove described 

 (from Withington to Slade Lane) at Cringle Brook 



These works commenced at Levenshulme in the Lower 

 Boulder-clay and continued in the same all along the Albert 

 Road westwards to Slade Lane, near which some very large 

 lumps of limestone were met with, from a ton to 30 cwt. 

 each. On turning southwards along Slade Lane the red 

 clay was entered opposite the Grange, and was drifted 

 through for about 270 feet. It came within about 12 feet 

 of the surface, and was covered with the drift- clay. The 

 Levenshulme limestone was next reached and was found 

 to be lying upon the red clay. It was drifted through al- 

 together for about 740 feet. The first limestones were 

 about two feet thick and bedded, with red-shale partings. 

 The limestone itself is of a delicate grey pink, and when 

 polished takes a marble lustre. It came at one point 

 within nine feet of the surface, but had a very irregular 

 outline and was much worn. The next was through solid 

 limestone, the course of the workings being nearly in the 

 line of the face of the rock. Upon this limestone lay a 

 band of ironstone six inches thick. The drift then passed 

 through broken metals for about sixty feet, after which 

 solid limestone was again entered and passed through for 

 seventy feet. The strata now became much disturbed by 

 a fault, as marked on Mr. Harper's section. Solid lime- 

 stone was again found beyond the fault, followed by broken 

 metals of brownish rock. The red sandstone was entered 

 at Cringle Brook where the Withington sewerage works 

 joined, and, as has already been shown, the red measures 

 continued thence to Withington, passing from Permians 

 into the Trias. The above description gives the impression 

 that there were several seams of limestone, but I do not 

 think this was the case. The drift appears to have run
