no doubt that he has made the island the first ornithological observatory in Europe. Almost every inhabitant was trained by him to observe and note the coming and going of the various species which visit that island during the seasons of passage, and almost every rare or unknown bird was brought to him for identification.
Of very tall and commanding presence, with flowing hair and beard (he reminded one always of what one pictured King Lear to have been), Gätke possessed an extremely genial and pleasant manner, and was a most entertaining companion. Always ready to impart information, he placed his notes most unreservedly at the disposal of any ornithologist who visited the island; and it is well known that the various articles on migration published by the late Mr. Henry Seebohm were based almost entirely on data obtained during his visit to Heligoland from the note-books of Mr. Gätke.
The writer some years ago spent a fortnight on the island with Mr. Gätke, and can testify to his extreme anxiety to render the visit of a fellow-ornithologist as pleasant and instructive as possible; and a more home-like, happy circle than that in his house would be difficult to find. Although of German origin, he spoke and wrote English like an Englishman, and was in some respects even more English than German.
Those who have known and learnt to appreciate his sterling worth will grieve deeply for him; but though he has gone his work remains, and his 'Vogelwarte Helgoland' will stand as a monument of industry and careful observation, carried on during a long and useful life. His intellect remained unimpaired to the last few days, and his end was a most peaceful one, carefully tended as he was by his devoted family.
