old and young flying westwards. He roughly estimated the 
numbers which passed within his ken as follows:—300 to 400 
Guillemots, 800 to 900 Razorbills, 8U0 to 900 Puffins, 100 Scarts, 
and 300 Sea-gulls. ‘This was performed in an east wind, during 
hazy or rainy weather (see also under Solan Goose), and all left 
Cape Wrath in one day and about the same time, viz., 10 a.m. 
The Gulls passed continuously between 9 am. and 8 p.m. 
Notes from other stations can hardly be considered as applying 
to anything but local daily migration in search of food, as is 
constantly witnessed at any rock-bird station on the coast; thus, 
at Rhu Stoir large numbers passed towards S.W., and are 
specially noted on June 12th to 15th; also at Kyleakin, a large 
flock passed southward at 2 p.m., wind S.E. When at the Shiant 
Isles this summer, at the end of June, I witnessed a regular 
departure of thousands of Puffins to their feeding-grounds in the 
Little Minch, about 9 to 10 a.m. 
Sea Guiis.—At Cape Wrath on Aug. 16th, three hundred 
passed west between 9 a.m. and 3 p.m.; wind E., haze, and rain. 
“Sea Gulls bred at the station, and all left on the same day, both 
young and old. The migration goes all to the west.” 
Kirriwake, Rissa tridactyla.—At Skervuile on May 31st, two 
at noon flying north; calm, clear. 
TrernN.—At Dhuheartach, six seen on the evening of Aug. 27th, 
wind 8., cloudy; and four at the same station on the morning of 
Sept. 4th. 
Birps unknown.—At Portpatrick on July 12th, a flock of 
small birds passed overhead at 8.30 a.m., wind §8.S.E., fresh, 
and rainy; and on Oct. 13th a flock passed inland at 4.20 p.m., 
wind §8.W., and rain; on Nov. 13th “a flock of birds not known” 
passed inland, wind E. by N., and clear. At Pladda on Aug. 20th, 
one Snipe, species not known, at 4 a.m., wind S.E., strong, and 
haze; and another on Noy. 15th. At Skervuile, on Nov. 14th, 
a number from 10 p.m. to 2 a.m., wind variable, light, and haze; 
and others on Oct. 7th at Skervuile; ‘‘many killed and fell into 
the sea.” 
RED-BREASTED MrrGANsER.—At Corsewall, on July 20th, a 
‘strange Duck” (since identified as a Red-breasted Merganser) 
was killed at glass at 2 a.m.; wind E., light, with haze.

stations upon our coasts, an extraordinary annual migration of
