HISTORY OF THE LICK OBSERVATORY.

The Observatory was founded by James Lick, by a deed of trust dated September 21, 1875. This deed devotes the sum of $700,000 to "the purpose of purchasing land, and constructing and putting upon such land .... a powerful telescope, superior to and more powerful than any telescope yet made; . . and, also, a suitable observatory connected therewith." The deed further provides that "if, after the construction

*To July 17, 1911.

of said telescope and observatory, there shall remain of said $700,000 any surplus," the surplus shall be invested and that "the income thereof shall be devoted to the maintenance of said telescope and the observatory connected therewith, and shall be made useful in promoting science; and the said telescope and observatory are to be known as the Lick Astronomical Department of the University of California." gift of Mr. Lick was accepted by the Regents December 7, 1875.

LOCATION.

The

Mr. Lick had already, in August, 1875, selected Mount Hamilton in Santa Clara County, as a site for the Observatory. Land for the site (1345.80 acres) was granted by Act of Congress in 1876. One hundred and ninety-one and forty-nine hundredths acres were granted to the University for the use of the Observatory in 1878. A tract of forty acres was added by gift of R. F. Morrow, Esq., in 1886. Three hundred and twenty acres were granted by the Legislature in 1888. A second Congressional grant, comprising 599.94 acres, was added in 1892. The Regents of the University purchased forty acres additional in 1901, 240 acres in 1904, and 125.42 acres in 1908. The total area is 2902.65 acres.

BUILDINGS AND INSTRUMENTS.

The Observatory consists of a Main Building, containing computing rooms, library (of 7500 books and 5000 pamphlets), and the domes of the 36-inch Equatorial and the 12-inch Equatorial and of Detached Buildings, to shelter the Crossley Reflector, the Meridian Circle, the Transit, the portable Equatorial, the Crocker, and the Floyd Photographic Telescopes. A fireproof building was completed in 1909. It contains vaults for the storage of astronomical negatives, observations and other records of value, and instruments temporarily not in use; together with photographic darkrooms and photographic and spectrographic laboratories. On the grounds are dwelling-houses for the astronomers, students, and employees, and shops for the workmen. The Observatory is well provided with instruments, some of which are enumerated below:

36-inch Equatorial; objective by Alvan Clark & Sons, mounting by Warner & Swasey. This instrument has also a photographic corrector of 33-inch aperture, figured by Mr. Alvan G. Clark.

3-foot Reflecting Telescope; presented to the Lick Observatory in 1895 by Edward Crossley, Esq., of Halifax, England. The large mirror of this instrument is by Sir Howard Grubb. An entirely new mounting has been constructed. The building was erected from funds subscribed by citizens of California.

12-inch Equatorial; by Alvan Clark & Sons.

6-inch Meridian Circle; objective by Alvan Clark & Sons, mounted by Repsold.

61⁄2-inch Equatorial Mounting; by Warner & Swasey.

61⁄2-inch Bruce Comet Seeker; objective by Brashear, mounting made at the Lick Observatory.

6-inch Crocker Photographic Telescope; objective by Willard, refigured by J. A. Brashear, who provided the mounting also.

5-inch Floyd Telescope; presented by Mrs. Peter Gopcevic (née Miss H. A. L. Floyd); interchangeable photographic and visual objective by

Alvan Clark & Sons.

5-inch Horizontal Photoheliograph; by Alvan Clark & Sons.

4-inch Transit; objective by Alvan Clark & Sons, mounting by Fauth & Co.

4-inch Comet Seeker; by Alvan Clark & Sons.

A Spectroscope, especially adapted for photography; given by Hon. D. O. Mills, for use with the 36-inch Refractor.

A Spectroscope, especially adapted for photography with the Crossley Reflector, and two Photometers for use with the 36-inch and 12-inch telescopes, provided from the proceeds of a gift from the late Miss C. W. Bruce, of New York City.

A 361⁄2-inch Cassegrain Reflecting Telescope, with modern dome and a 3-prism spectrograph, the gift of Hon. D. O. Mills, for use on an astronomical expedition to the southern hemisphere. This expedition is now at work, on the summit of San Cristobal, in the northeast suburbs of Santiago, Chile.

[blocks in formation]

The Regents have established in the Lick Astronomical Department three salaried fellowships. These usually permit the holders to pursue studies and undertake investigations in fulfillment of requirements for the degree of Doctor of Philosophy. It is essential that each successful applicant shall be a graduate of a college or university of high standing, and shall have decided to make astronomy or one of the related sciences the basis of a professional career. Applications should be made in writing to the Director of the Lick Observatory.

MARTIN KELLOGG FELLOWSHIP.

A fellowship in the Lick Astronomical Department has been endowed by Mrs. Louise W. B. Kellogg in memory of her husband, Martin Kellogg,
