to run through the entire thickness of the wall. The sill, likewise, is a single 

 slab, running through the wall. There is a socket-stone for the lower horn 

 of the door, and a projecting sill inside ; and there are traces of the stone which 

 received the upper horn of the door, but this is broken away. There are two 

 holes like putlog holes, one at each end of the sill, roughly broken in the 

 masonry on the outer face of the wall ; they are possibly meant for receiving 

 the supports of a platform. (2) On the north side, above the level of the 

 doorway, a window with a triangular head on the outside, square inside, 

 made of two slabs of stone meeting at an apex, w^ith a tympanum recessed 

 within. 'J'his is shown in Plate XIY, fig. 2. (3) About half-way up the 

 tower, above the doorway, a square-headed opening. (4) On the south side, 

 still higher up, another square-headed opening. 5) Another square-headed 

 opening, near the present top, on the west side. 



The following traces of floors are to be seen inside the tower : ' 1 ; At the 

 level of the door inside, an offset. (2) Sixteen courses above this, a row of 

 large undressed blocks projects into the interior of the tower, evidently 

 corbels to support a second floor. This floor was probably of stone, needing 

 therefore a stronger support than the others. (3, 4, 5j Three other offsets 

 at more or less equal distances between the corbels and the top of the tower. 



The tower is built of fairly large stones, which are well dressed to the 

 curve of the wall. 



I add the following from the Ordnance Letters' : — " On this island, stands 

 a round tower, which is locally called clogds,- and is a splendid construction of 

 large stones, bearing strong resemblance in this i-espect to the round tower of 

 Uoscrea." Then follow measurements, after which the wiiter pi-oceeds : " The 

 lower part of the tower inside, is tilled up with clay as high as the door. At 

 the depth of -i feet below the surface of this clay, long stones jut out, it is 

 said, from the wall of the tower, so as to form a floor (or a support for 

 a floor ?). 



" Henry Boucher, the grandfather of Henry Allen, who lives at the lake 

 opposite the island, and who went with me into it, saw an iron door on this 

 tower. The traces where it was fastened, are still visible to the left, as one 

 enters ; and the traces where it was bolted when closed, are visible on the 

 right. There is a bit of iron said to be a part of a holdfast, inserted in a stone 

 on the left as one enters. It is supposed to have been fixed in the stone at 

 the time of the building of the tower, Most of the stones at the door, all of 

 which are chiseled, extend the whole thickness of the wall.
