The next move was to New York City, where for a year he conducted a private gymnasium on the site afterwards occupied by the Madison Square Theatre Company. “I elaborated my old system of measurements,” he says, referring to this period, “and had the first patterns of my long-contemplated developing appliances constructed. These consist of what are familiarly known as chest-weights, chest-expanders and developers, quarter-circles, leg-machines, finger-machines, etc., to the number of forty different pieces....[261] The attempt was made to ascertain the strength and physical condition of the individual by dynamometers, and other testing and measuring appliances, and then to adapt the apparatus by means of pulleys, levers, adjustable weights, etc., to the strength or weakness of the person as determined by the physical examination.” [Illustration: FIG. 78.—Frontispiece to Captain Chiosso’s “The Gymnastic Polymachinon” (1855).] Meanwhile the Hemenway Gymnasium was nearing completion, and the attention of the Harvard authorities, in search of a man able to insure the best use of such splendid facilities for physical training, was turned to Dr. Sargent by alumni living in New York, and especially by William Blaikie (1843-1904), whose “How to Get Strong and How to Stay So” had just been published (New York, Harper & Brothers, 1879). In the chapter on “What a Gymnasium Might Be and Do” he sets forth Harvard’s opportunity in language that now sounds prophetic, and here and elsewhere in the book makes repeated mention of Dr. Sargent’s work at Bowdoin and Yale and of the new apparatus which he was then introducing. On September 22, 1879, the Corporation appointed him assistant professor of physical training and director of the Hemenway Gymnasium.[262] His first task was to determine the equipment and to superintend its construction and installation, and the building, therefore, was not ready for use until the following January. In the _Harvard Register_ a month later he explains that the older gymnasia were “filled with crude appliances that have been handed down in stereotyped forms for several centuries (!). To use this apparatus with benefit, it is necessary for one to have more strength at the outset than the average man possesses.... When it is considered that only one man out of five can raise his own weight with ease, the need of introductory apparatus to prepare one for the beneficial use of the heavy appliances becomes quite apparent. It was the realization of this need that led to the invention of the numerous contrivances that have been introduced into the Hemenway Gymnasium; the desire to strengthen certain muscles, in order to accomplish particular feats on the higher apparatus, was the original motive.... The results which followed were so satisfactory that the same appliances were afterwards used as a means of attaining a harmonious development. For this last-named purpose each machine has its own use. Each is designed to
