New Telescope for the Observatory.

The Observatory, through an anonymous gift of $20,000 received in 1902, has added to its equipment what is regarded as the largest efficient telescope in the world, a five-foot aperture reflecting instrument constructed by the English astronomer, the late A. A. Common. Professor E. C. Pickering conducted the negotiations for the purchase of the telescope during the summer, and preparations are now being made for packing and transferring it to Cambridge. The mirrors will be sent first for experimental purposes previous to setting up the whole instrument. An open space in the eastern part of the Observatory grounds near Bond street has been chosen as the site for the telescope. On account of its great height, about 27 feet in focal length, no dome will be erected.

The telescope will be used mainly for photographic work.
