north-east of Ramelton, by the new road to Glenalla. At one 

 time it was [a boggy lake, and a bank seems to have been built 

 across its embouchure, to utilize it as a mill-pond. Subsequently the 

 peat in it was cut, and its level lowered by a canal. Now, the cut 

 from the site of the old lake has been made so deep, that the tract, 

 at will, can be entirely drained, so that it is a mill-pond in winter 

 and a peat bog in summer, according as the sluice is down or up. 

 When the waters are out it can be seen that some of the deal 

 corkers in the area are in the position in which they originally 

 grew, while others were evidently originally at a higher level in 

 the peat, and were dropped down by the peat being cut away from 

 under them. There are others also in a sedimentary peat; and 

 although they look as if in their original natural positions, which 

 some of the turf-cutters say they are, yet it seems to me quite 

 possible that they may be "dropped corkers," around which 

 recent sedimentary peat, the washing from the turf-banks and 

 holes, may have accumulated. 



Nos. III. and IV. Cam and Thorn Lakes. — These lie north 

 of Glencarn Bog, in the vicinity of the road. In both, especially 

 the latter, there are numerous deal corkers, most, if not all, of 

 which are in their original positions. In connexion with these 

 lake basins, it is possible that the drainage from them was stopped 

 by the accumulation of peaty matter. 



No. Y. Pollet Lough, between Doagh Bog and Fanad Light- 

 house, in the north-east portion of Fanad. — This loughaun is 

 situated in a shallow, bowl-shaped depression. Numerous deal 

 corkers, the majority evidently in situ. No apparent old site of a 

 drainage vent. 



No. YI. Kindrum Lake. In Fanad- within-the-Waters. — In 

 the south-west arm of the lake is a cut-away bog, with deal 

 corkers in situ. The stream from the lake is now a mill-race, the 

 water of the lake being lowered in summer to allow the peat to be 

 cut. The mill-race is cut in a stony drift, that never could have 

 been brought into its present position by the lake waters. 



No. VIL Tawney Lough, near the village — Numerous corkers 

 in a saucer-shaped depression. They are evidently in their 

 natural positions ; while there are others that show the marks of 

 the turf-cutters. The present drainage of the lake is a deep cut 

 through the drift rim.
