any distant removal, since they repose on rocks of a precisely 
similar kind ” (p. 179). 
Professor Heddle of St Andrews informs Convener that he 
examined these stones, and thought they had been detached and 
wrenched off from other rocks, and moved in a direction towards 
E.S.E. (^Eighth Report, p. 7). 
Fair Isle Parish.— ^qy. Mr Laurence, catechist, reported that 
there are no boulders above 10 tons, but that there are several small 
boulders of Conglomerate quite differing from any rocks in island 
{Eighth Report, p. 7). 
He adds that there was one large block of sandstone which was 
blown up in 1880. It differed from any rocks in island, and was 
similar to the Eday sandstone. 
The island of Eday is about 13 miles to S.S.W. of Fair Isle 
{Eighth Report, p. 8). 
North Unst . — All over Unst the rocks show abrasion, and, in 
many places, deposits of drift, enclosing stones of various sizes. 
Mr Peach, senior, at the request of the late Sir Roderick 
Murchison, examined this most northern isle of the Shetlands, and 
gave in a Report to the British Association in the year 1864. He 
stated that he “ascended the Muckle Heog Hill, reaching to a 
height of 500 feet; and found the W.lsT.W. end vertical, and 
polished to the depth of at least 150 feet.” Professor Geikie in an 
article in Nature, of 17th September 1877, refers to the foregoing 
report by Mr Peach, and says “ that from his own observations he 
can speak confidently as to the correctness of Mr Peach’s deter- 
minations.” 
Sumburgh Head. — Conglomerate botilder lying on sandstone 
rocks {Second Report, p. 44). 
In addition to the information in the foregoing notes, regarding 
boulders, it is right to refer to the information given by Messrs 
Peach and Horne (in their paper on the Shetlands) regarding the 
extent to which all the hills, even the highestj show traces of glacia- 
tion {Jour, of Lond. Geol. Soc. for November 1879). 
They say — that “ from Sumburgh Head northwards to Unst we 
found everywhere the clearest evidence that Shetland must have 
been at one time smothered in ice ” (p. 706), 
“ It is apparent, on a moment’s consideration, that the direction of
