jecting eve stone, which, when complete, must have added greatly 
to the effect of the whole. This is indeed the only attempt at orna- 
ment in the entire building. 
In two of the compartments above mentioned, are two small 
doors: the one, two feet three inches wide by three feet one inch 
high; the other, two feet eight inches square. ‘These open into 
two cells, in the interior of the wall, of different dimensions, both 
of them seven feet eight inches high: but one, seven feet ten inches 
long by five feet wide ; the other, twelve feet long by four feet eight 
inches wide. ‘These are constructed with flags, the one projecting 
over the other, until they come to the top, where a single flag 
finishes. Their figure is oval; and, though built, as before observed, 
without cement, they are water proof. 'This completes the descrip- 
tion of the inside. On the outside, a moat or fosse, of twenty-six 
feet wide and six feet three inches deep, surrounds the whole 
building. This moat is sunk into the gravel, and the side nearest the 
building slopes up to the foundation about fourteen feet ; which, being 
merely laid upon the surface of the ground, and not sunk, on ac- 
count of the natural swell of the hill, elevates the building above the 
opposite side of the moat. The wall rises on the outside, upon an 
average, about eighteen feet. The inequality in its height is oc- 
casioned by the irregularities of the ground, upon the original 
surface of which it was built, it being, where perfect, level on 
the top. In that part, where I took my measurement, it is seventeen 
feet six inches high. It is remarkable that it does not rise 
perpendicularly ; but batters two feet seven inches to the top: 
not In a straight direction, but with a curve, (expressed in the plan 
but difficult to be described,) which has a very striking effect. It 
also batters on the inside, about three feet ten inches, so that it 
reduces from thirteen feet at the bottom to seven feet at the top.
