XXXII. Note on a Section of Boulder-clay containing a Bed of Peat

About two miles east of the town of Airdrie, at Burnhead quarry, there has lately been exposed a section of clay, apparently Boulder-clay. I do not positively assert that it is so until I have made further investigations, and, therefore, I only wish now to make a statement of actual facts which can speak for themselves. Indeed I would not have brought the subject before your notice at all at this time unless I had thought that during the summer months there would be a good opportunity for some of the members to examine the section for themselves, and perhaps decide the question, especially as every one knows that when a section such as this is fresh, it is much better seen than after weathering influences have had an effect on it. I may, however, add that several geologists of note who have visited the quarry have expressed their opinion that the section is true Boulder-clay. This section of Boulder-clay, containing a bed of peat which was brought to light through a downthrow of the dolerite on the north side of the quarry, is about 12 feet thick, and the Boulder-clay appears to lie both above and below the peat, but as it dips to the north, the thickness cannot be at present ascertained. The peat is 17 inches thick in the section; when split up into layers, as it readily does, it is of a pale-brown colour, but turns of a darker shade when exposed for a few minutes
