_Butt of Lewis._--Robert Agnew (replacing Mr Edgar, who is now at Lochindaul, _q.v._). Mr R. Agnew is a son of Mr Joseph Agnew, late keeper at Isle of May (East Coast), now stationed at Monach Isles, _q.v._ Mr R. Agnew sends, in all, two excellently well-filled schedules from the Butt of Lewis. Under date of November 9th, 1886, he writes: "I send you a schedule. I hope you will find it of use. I would have sent it sooner, but wrote to my father for the loan of a book to help me, and waited till I heard from him." [Schedules sent date from August 23d to February 7, 1887.] Mr Agnew continues: "I am surprised to see that most of the strange birds that I have seen here are _single_. It must just be occasional stragglers that we get from the flocks that are passing. It is also strange that there are so few birds coming to the lantern, but the tower is very high--120 feet--and perhaps that is the reason." [Mr R. Agnew is right in believing that stragglers are all that can be expected to appear at Butt of Lewis, though possibly in exceptional seasons unusual numbers may appear. Birds "catch up" at Cape Wrath and W. C. of Scotland. Remnants "catch up" again at Butt of Lewis. But in easterly gales the "catch up" of the land is often lost, and hundreds or thousands are carried clear away to the Atlantic. See previous Reports.--J. A. H.-B.] Mr Agnew continues: "I have marked a Hen Harrier, and by the description in the book" [he having received the loan of the book from his father--Mudie's "Birds"], "I think I am right. He remained here for some time, and the poor Rock Pigeons led a poor time of it. I also found a young Gull he had killed and eaten. I was surprised to see it, because I did not think that he would have attacked so large a bird. I measured the wings, and found them to be 4 feet 2 inches from tip to tip." [Mr R. A. sent me the wings, but they did not reach me, and must have miscarried, but no doubt it was one of the common species of Gulls; from the measurements, probably a Herring Gull; or possibly--_i.e._, if the measurements are correctly taken across the back and wings--an Iceland Gull. (See MacGillivray's "Manual," under the said species, vol. ii., p. 247.)--J. A. H.-B.] Mr R. A. says: "I only came here last summer, and did not begin to keep records till near the end of August, but another year I hope to be able to do better." [Meanwhile, we can only thank Mr R. A. for his excellent commencement of the work, which is well done.--J. A. H.-B.]
