MR MILNE ON THE MID-LOTHIAN AND EAST-LOTHIAN COAL-FIELDS. 



At Catscraig, on the shore of East-Lothian, about three miles south of Dun- 

 bar, the shelly deposit may be seen covered by a layer of gravel and boulders, al- 

 together similar to that which is represented in the foregoing figure. 



As this deposit thus lies above the deposit of sand and shells last described, 

 it is hardly necessary to observe, that, in certain situations, it may be expected 

 to be seen covering all the older deposits successively. 



It may be seen at a great many places covering the layers Qifine sand which 

 forms No. 5 of the series. It may be seen, for example, in the cut lately made 

 for the Newhaven Railway, between Easter and Wester Waniston, — as repre- 

 sented in the following section : —

Figs. 1 and 2 are intended to represent sections of the two sides of the ciit, 

 — fig. 1 being the west side and fig. 2 the east. A, represents the existing soil 

 or mould of vegetation ; — B, layers of gravel belonging to the series now described, 

 and lying upon beds of sand which belong to No. 5 of the series. C, represent 

 layers or laminm composed of smaU fragments of coal, none exceeding a man's 

 hand in size. The layers are not more than 3 inches thick. D, are slips or fis- 

 sures which intersect the gravel and the sand. E, are the laminae of the sand-bed, 

 which, as mentioned in a previous part of this paper, are, near the sides of the 

 bank, inclined to the horizon at an angle of about 40°. 



The depth of the sections represented by these figures is about 40 feet, and 

 the length 200 feet. 



In a cut made for the Fisherrow Railway, near Newhailes, I noticed a simi- 

 lar bed of small gravel, overlying the sand. 



This deposit of gravel may be seen covering the houlder-day in the old quaiTy
