222 REPORTS ON THE STATE OF SCIENCE.—1912. 
the island are the remains of a Dun, or are the actual foundations, 
is not now easily determined, but I incline to the view just stated. 
“In addition to those mentioned in my former letter, there appears 
to be an artificial island on Loch Orisay (spelt phonetically) between 
Grimsheder and Loch Chlathamir, in the parish of Lochs. The Road 
Surveyor, Mr. MacLeod, informs me that the island is undoubtedly 
a ‘‘ built island."’ It may be of interest to know that some years ago, 
when alterations in the water-supply system to Stornoway were 
rendered necessary, the loch from which the town’s water is drawn 
(Loch Aird-na-lice) had to be partially drained. At the N.W. 
corner of the loch, some yards from the shore, a-perfectly formed 
island was exposed consequent on the draining operations, and it still 
exists, but now, of course, totally covered by water. If I remember 
rightly some stakes were found about it. I am afraid I have not 
helped you much, but if I can be of any further service, please com- 
mand me—Yours very truly, C. G. Mackenziz.’ 
With the example at Tolsta, the most north-westerly point of the 
British Isles, and a site which may yet prove of the greatest interest, 
I shall conclude this list of the Artificial Islands which have been 
notified in reply to the circular issued by the Committee. That so 
large a number have been suggested is surely matter for congratula- 
tion, for even if some should eventually be found to ‘ draw blank,’ 
the evidence in the vast majority of cases is quite conclusive. 
Remembering, as I do, the welcome accorded to my paper suggest- 
ing the first addition to the then-known examples, I cannot but wish 
that the same congratulations should be offered to each of those who 
have succeeded in adding to the list. I feel sure that I am express- 
ing the feelings of the Committee when I cordially thank each of the 
correspondents for the information which they have, often with con- 
siderable trouble, elicited in regard to the examples in their various 
districts.
