old and young flying westwards. He roughly estimated the 

 numbers which passed witliin his ken as follows : — 300 to 400 

 Guillemots, 800 to 900 Razorbills, 800 to 900 Puffins, 100 Scarts, 

 and 300 Sea-gulls. This was performed in an east wind, during 

 hazy or rain}' weather (see also under Solan Goose), and all left 

 Cape Wrath in one da}' and about the same time, viz., 10 a.m. 

 Tlie Gulls passed continuously between 9 a.m. and 3 p.m. 

 Notes from other stations can liardly be considered as applying 

 to anything but local dail}' 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 

 dei)arture of thousands of Puffins to their feeding-grounds in the 

 Little Minch, about 9 to 10 a.m. 



Sea Gulls. — At Cape Wrath on Aug. 10th, three hundred 

 passed west between 9 a.m. and 3 p.m. ; wind E., haze, and rain.

 young and old. The migration goes all to the west."

 small birds passed overhead at 8.30 a.m., wind S.S.E., fresh, 

 and rainy ; and on Oct. 13th a flock passed inland at 4.20 p.m., 

 wdnd S.W., and rain ; on Nov. 13tli "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 Nov. loth-. xVt Skervuile, on Nov. 14th,
