Astronomical Observatory Report.

The annual report by the director of the Astronomical Observatory has been issued, containing as usual the financial statement of the Observatory, and a report of the work during the past year.

Professor Pickering makes in his introductory address to the President, an urgent appeal for money, and details some of the pressing needs of the Observatory, among which is the demand for new fire-proof buildings. In particular is it essential that the library of 29,393 volumes and pamphlets, one of the most complete of its kind in the country, should be protected from fire.

In addition the report contains a detailed statement of the work carried on this past year in Cambridge, in the southern station at Arequipa, Peru, and at the meteorological observatory on Blue Hill.
