124 C. R. Wilson — Topography of old Fort William. [No. 2, 
mistake till he came to put in the details of the rooms along the east 
curtain south of the gate. Then, finding that there was not sufficient 
room to put those details in properly, he crowded them in together, 
This, I think, is clearly the case with the cross walls. The discrepancies 
between Wells’s plan and the results obtained by actual excavation may 
be exhibited as follows : — 
Wells’s plan shows walls at 43, 70, 95, 108, 122, 135 ft. 1 from tho centre of 
Excavation shows walls at 75, 100, 126, 146 ft. ) the East gate. 
Looking at this comparative table, and remembering that Wells’s 
distances are short of the true distances, we easily discover which walls 
correspond. The first cross wall shown by excavation (aa L ) corresponds 
to the second wall given in Wells’s plan. The second cross wall shown 
by excavation (bb^ corresponds to the third wall in Wells’s plan. The 
fourth cross wall shown by excavation (cc x ) corresponds to the fifth wall 
in Wells’s plan ; and the last wall in Wells’s plan corresponds to tho 
last wall shown by excavation. The two missing walls not shown by 
excavation are the first cross wall of Wells’s plan, which was the south 
wall of the barracks (w), and the fourth wall of Wells’s plan which 
must have come between bb l and cc L . This wall could not have been 
a very substantial one, as it must have been built over the subterranean 
chamber b'bf o'c{. The room tt in Wells’s plan, which is tho southern- 
most of the series of rooms built within this part of the east curtain, 
and is, therefore, the Black Hole, corresponds with the space cc x dd v 
This is the site of the Black Hole. As regards the staircase to the 
south-east bastion, I have unfortunately very little to say. This stair- 
case is mentioned by Hoi well and is shown by Wells in his plan. It is 
a long staircase. Its head is put by Wells at about 8 ft. from the south 
face of tho southernmost cross wall, and its foot at a distance of about 50 
ft. I have not been able to find any trace of it by excavation, but I 
see no reason for doubting its position to be correctly marked by Wells. 
If I might be permitted to make a few conjectures I should arrange 
tho rooms along the east curtain thus. The 
Arrangement of the w h 0 le range of rooms is contained between 
rooms along the east & 
curtain. Ike south wall of the east gate CG 1 G z and the 
cross wall dd± and between the east curtain

pillars of these arches were about 8 ft. 9 in. distant from each other 
from centre to centre. West of them came a second parallel line of 
arches, forming the piazza before the rooms. The first of tho 
cross walls dividing off the rooms occurred after tho fourth arch in 
the first line of arches C y D v Thus it would be about 35 ft. distant 
from tho wall CC L G%. These four ai’clies were left quite open to tho
