The eider ducks, which on the 20th September were represented by a solitary individual--the first arrival--now number over a hundred. The longtails are still awanting to complete our list, but their advent may be looked for early next month. On suitable nights for the past two months we have always had some feathered visitors “becking and booing” to us through the lantern. On 4th October an extremely rare visitor--here at least--made its appearance, namely, the ring-ousel, the first I have seen. In size, shape, and general colouring, this migrant might easily be mistaken for a hen blackbird, but for the conspicuous white crescent across the throat, in this instance somewhat faint, but well defined, owing possibly to the bird being in immature plumage. On the morning of the 24th October over two dozen tiny gold-crest wrens were circling round our lantern, jostling and tumbling over each other in frantic efforts to keep in line with the white flash, the red flash evidently having no attraction for them. A skylark and robin were also of the company, as well as several redwings. The robin always seems to have a truer sense of his position than any other of our visitors. While the others clamour futilely against the glass he maintains an aloofness and self-possession truly remarkable. His eyes seem to be everywhere, and only with difficulty and the exercise of a little strategy is his capture effected. Of course, our captures are but temporary, and merely for the sake of a few minutes’ examination. We had rather a disappointing experience with the Channel Fleet while cruising in these waters last month (September). Passing north in the dark, we were quite unaware of their presence, the _Sutlej_ alone being seen later steaming north at 6 p.m. on the 21st, nearer to Arbroath than to us. On returning south a string of brilliant lights passing three miles outside of us at two o’clock in the morning was all we saw of the procession. On 29th October a flock of thirteen field-fares passed at 9 a.m., flying towards Arbroath. This is the first arrival here of these birds, and earlier than usual. On examining a lark which had been killed on the lantern the other night, a small land shell was found adhering to the feathers on the under part of the body. Arguing from this instance, the assumption that they also are imbued with the migratory instinct and adopt this mode of travelling would probably be considered far-fetched. That there is much undreamt of in our philosophy is as pregnant as when uttered, and possibly the connection between mollusc and bird was due to circumstances other than purely accidental. _NOVEMBER 1903._
