Besides the boulders pointed out by Dr Hibbert, Messrs Peach 
and Horne say that on Papa /SYowr they saw others of “ Old Bed 
rocks, derived from the area occupied by the rocks between Sand- 
ness and Bixiter Voe;” — places on Mainland, situated to the S.E. 
of Papa Stour, and separated from it by an arm of the sea. 
Hilswick NesSf the south end of an isthmus, on the north side of 
St Magnus Bay. 
Dr Hibbert refers to a transported boUldet on the summit of this 
promontory ; — describing it as “ a surprising block of granite ; — ■ 
removed from a rock, the nearest site of which is about 2 miles 
north” {Edin, Journ. Science^ vol. iv. p. 89). 
Messrs Peach and Horne, who had not mentioned this boulder in 
their paper, adverting to Dr Hibbert’s notice of it^ say that “ this 
boulder might have been derived from some of the masses of the 
same material, lying at a slightly greater distance to the E. and 
H.E. of Hilswick” [Geol. Mag\ for August 1881, p. 372)* If that 
view be taken, the transport must have been across an arm of the 
sea running H. and S. on the east side of Hilswick Hess. 
Roeness Hill, on Horth Mavine, 1476 feet high; — Dr Hibbert 
says, this hill being “ composed of red granite^ I was struck with the 
immense number of boulders of a primary greenstone', which appear 
to have been removed from a site 2 or 3 miles oil’, and to have been 
brought in a southerly or south-westerly direction up a gradual 
ascent of 3 or 4 miles {Edin. Joiirn, Science, vol. ivi p* 89). 
Messrs Peach and Horne admit the facts as here stated. They 
say they “ entirely support our conclusions, viz.j of the boulder 
having been carried up hill by the Scandanavian ice-sheet, in a 
S.W. direction” {Geol. Mag. for August 1881, p. 371). 
Additional Localities . — The Kev, Dr Gordon of Birnie visited 
Shetland in the year 1872, and sent to the Committee the following 
notes 
(1) Boulders. — Hear Horth Mavitie (the extreme north of Main- 
land) there are large boulders between Hilswick and Ollaberry. He 
sent to the Committee pencil sketches of three boulders, situated 
in the same Horth Mavine district, between St Magnus Bay and 
Yell Sound. They are syenitic. One near Eela water is 16x12x6 
feet. Another called Crupnd (bent) is 11x8x8 feet. The third 
called Bonhus, situated between the other two, is8xl0xll feet.
