Holcomb and others, he attempted to establish a Lyceum Village at Berea, Ohio, where until 1852 he was engaged in the manufacture of globes for class- room use. The Lyceum Village collapsed after a few years, however, and plans for a "central Lyceum Village" in the neighborhood of New York failed to materialize. Holbrook resided in New York, 1842-49, as secretary of a central bureau, part of his original lyceum scheme, through which lecture courses were arranged and cabinets of minerals and other scientific specimens and illustrations of the work of chil- dren in the schools were exchanged. From 1849 until his death his home was in Washington, D. C., where he continued to labor for the promotion of the Lyceum system. Throughout his career he carried on an extensive correspondence and was a prolific writer of tracts and pamphlets. While on an excursion to collect specimens of minerals and plants in the vicinity of Lynchburg, Va., he was drowned in Blackwater Creek. Two sons survived him, one of whom, Alfred [q.v.], mani- fested his enthusiasm for popular education in the development of the National Normal Uni- versity (later Lebanon University) at Lebanon, Ohio. [The chief sources for Holbrook's life and work are his many writings in pamphlet form, particularly the Self Instructor and Journal of the Universal Lyceum for March 1841 and The American Lyceum or Society for the Improvement of Schools and Diffusion of Uni- versal Knowledge (1829). Biographies somewhat at variance as to dates may be found in F. B. Dexter, Biog. Sketches Grads. Yale Coll., vol. VI (1912) ; and Henry Barnard's Am. Jour. Educ., Mar. 1860. See also Am. Jour.

Elijah Holcomb, a farm- er and cooper, was able to afford his son only the scantiest education in the common school, but the family came into possession of the extensive library of an uncle who was lost at sea, and Amasa with this help was able to gain a working knowledge of the mathematical sciences. He ap- plied himself so intensively that at fifteen he obtained the position of teacher in the district school at Suffield, Conn. Continuing his study of mathematics and astronomy, in which he was particularly interested, he observed the solar Holcomb eclipse in 1806, with apparatus of his own manu- facture, and a year or two later undertook the computation and publication of a series of alma- nacs. He subsequently took students into his home for instruction in advanced studies and for a time supplemented this work with surveying to gain a livelihood. To supply the needs of his stu- dents as well as to equip himself, he entered upon the making of compasses, dividers, scales, and other instruments as a business, and soon enjoyed more than a local reputation for the quality of his products. Some time after 1825 he began the manufacture of telescopes, first for his own and his students' use, and later, as his repu- tation grew, for general sale. Up to this time most of the precision and optical apparatus in use in America was made in Europe, and of tele- scopes very few, if any, were of domestic manu- facture. In the American Journal of Science and Arts of January 1833, Prof. Benjamin Silliman of Yale announced that Holcomb was making spyglasses of every description, and achromatic and reflecting telescopes. These latter were of the type perfected by Sir William Herschel. They were from eight to twelve feet in focal length, and would "perform more than the im- ported instruments of the same prices." Profes- sor Olmsted, also of Yale, lent his name to the announcement. In the same Journal for 1835, Silliman added that Holcomb had "prosecuted his enterprise with great diligence and ingenuity/' and had brought his instruments "to a degree of perfection, which enables them to sustain a very honorable comparison with the large telescopes imported from abroad." The simple mounting was especially remarked. In the same year Hol- comb submitted two telescopes to the Franklin Institute of Philadelphia for examination. The committee on science and the arts reported them very favorably, commended the mounting, and recommended Holcomb for an award and medal from the John Scott legacy fund The following year the same committee reported upon a tele- scope made by Holcomb for Delaware College. This instrument, which had a focal length of fourteen feet, was described as superior to any that Holcomb had hitherto made, and as having "every attribute of excellence which the best optical skill could give to an instrument of these dimensions" (Journal of the FrankUn Institute, November 1836, p. 312). With the introduction of the Daguerreotype, Holcomb experimented in photography and added cameras to the instru- ments which he made. He was active in public affairs, serving many terms after 1816 as a se- lectman and assessor of Southwick, Mass. In 1832-33 he represented the town in the Massa-
