Lark.--The most northern station noted this year was Dhuheartach, and thence southward they are noticed at M'Arthur's Head, Skervuile, Rhinns of Islay, Lamlash and Corsewall. The earliest date is Aug. 17th, when twenty struck at Dhuheartach between 10 p.m. and 3 a.m.; wind W., with haze. The latest date is Dec. 6th, when one struck at 9 p.m.; wind S.E., fresh, and haze, at Corsewall; the time thus occupied was one hundred and twelve days (but the last was no doubt due to the severe frost inland at that time). The previous date is Nov. 18th, which would make the time only seventy-nine days. The greatest rush appears to have been in October, about the 12th to 24th, but the numbers observed are so small that it is difficult to judge. The locality most favoured was Dhuheartach, whence I have returns on eight different dates, between Aug. 17th and Nov. 24th. An earlier rush took place about Aug. 17th to 21st, at Dhuheartach and Skervuile. A later rush about Nov. 15th to 18th at Dhuheartach, Skervuile, and Rhinns of Islay, but of small dimensions. Larks appear to migrate principally when the wind is W. to S.W., or late in the season, when still more southerly, say S. Exceptions occur at Dhuheartach on Nov. 24, when wind was N.E., fresh, and weather clear; at Rhinns of Islay on Nov. 7th, wind N.W., light breeze; at Skervuile on Oct. 10th, when wind was N.; they migrate in calm, variable, light, or fresh winds, and are noticed at lanterns principally in haze and fog. They migrate mostly at night, at all hours, but the majority pass between 7.30 p.m. and 4 a.m. Those passing during the day were travelling when the wind was N. or N.E.; those passing at night when the wind was S. to W. So the returns show; but whether this indicates any _law of migration_ or not remains to be proved by further observation. Lapwing.--The most northern station which they were observed to pass at this season was Rhu Stoir; thence southward, they are reported at Isle Ornsay, Lochindaul, Devaar, Pladda, and Portpatrick. The earliest date given is Aug. 20th, when "flocks" were seen during the day in N. wind and clear weather; the latest is Dec. 11th, when one was killed at Pladda, at 2 a.m., wind S.E., light breeze, with haze. The next latest date given is Nov. 14th, when twenty-two were seen at 8.30 a.m. at Portpatrick, wind S.E., and haze. The time occupied, therefore, this year is from eighty-six to one hundred and thirteen days. Rushes took place about the 20th to 25th August, when several flocks passed Isle Ornsay and Lochindaul; again, Sept. 16th to 25th, a flock at Devaar, Portpatrick and Chickens Rock; another rush at Rhu Stoir, Portpatrick and Lochindaul about Oct. 27th. Lapwings travelled in clear or haze, rain, or showers, principally in S. and S.E. winds, on the west coast; but also in N. wind on Aug. 20th, and in W. and S.W. at Rhu Stoir and Lochindaul on Oct. 23rd and Nov. 1st respectively They appear to travel equally by day and night.
