_Note._--Herr H. C. Müller informs me that a lighthouse will be shortly erected at Nossoe, in Faroe, eighty feet above the sea. Herr Müller considers that this will prove a good station for observing birds during migration. Suderöe would also be a good observatory. He also told me of the occurrence, for the first time, of _Sciurus noveboracensis_ at Nordtalik, Greenland, about May, 1882; and of the occurrence also of a young Sabine's Gull at the same place. I have a young Sabine's Gull, brought home last year (1883) by the whalers to Dundee. Of the progress of the scheme of accumulation of migrational data in other parts of the world, we may notice here that Dr. Arthur proposes to take up the subject at the lighthouses in New Zealand, and will send the Committee his schedules for arrangement. Our American friends have made a promising start with similar intentions, but of a much wider scope, as is shown by the circular, which we here reprint, as it will show to our reporters other collateral subjects which offer plenty of opportunity for observation, and which can easily be made as applicable here as in North America, as regards our commoner species. Schedules somewhat more elaborate than ours have been issued also to lighthouses in America:-- "At the first congress of the American Ornithologists' Union, held in New York City, Sept. 26th-28th, 1883, a Committee on the Migration of Birds was appointed. It is the purpose of this Committee to investigate in all its bearings, and to the fullest extent possible, the subject of the migration of birds in the United States and British North America. The work will not be limited to the accumulation of records of the times of arrival and departure of the different species, but will embrace the collection of all data that may aid in determining the causes which influence the progress of migration from season to season. For example, severe storms, gales of wind, protracted periods of unusually high or low temperature (for the locality and time of year) are among the atmospheric conditions that are known to exert marked effects upon the movements of birds. The opening of the leaves and the flowering of certain plants, with the correlative appearance of a multitude of insects, are also among the factors that have to do with the abundance of many species. Hence the careful registration of certain meteorological phenomena, and of the state of advancing vegetation from day to day, will constitute prominent items in the record books of the observer. "For convenience in collecting and arranging the enormous mass of material which will be accumulated by the joint labours of this army of field workers, it has been deemed advisable to divide the vast expanse of territory embraced in the United States and British North America into thirteen districts, each of which will be placed under the immediate direction of a competent superintendent."
