The Company also made an earnest effort to promote the manufacture of glass in Virginia. This industry was threatened with extinction in England as a result of the great inroads that had been made upon the timber available for fuel, and it was thought that Virginia, with its inexhaustible forests, offered an excellent opportunity for its rehabilitation. But here too they were disappointed. The sand of Virginia proved unsuitable for the manufacture of glass. The skilled Italian artisans sent over to put the works into operation were intractable and mutinous. After trying in various ways to discourage the enterprise, so that they could return to Europe, these men brought matters to a close by cracking the furnace with a crowbar. George Sandys, in anger, declared "that a more damned crew hell never vomited".[156] In order to show that they were sincere in their professions of interest in the spiritual welfare of the Indians, the Company determined to erect a college at Henrico "for the training up of the children of those Infidels in true Religion, moral virtue and civility".[157] The clergy of England were enthusiastic in their support of this good design, and their efforts resulted in liberal contributions from various parts of the kingdom.[158] Unfortunately, however, the money thus secured was expended in sending to the college lands a number of "tenants" the income from whose labor was to be utilized in establishing and supporting the institution.[159] As some of these settlers fell victims to disease and many others were destroyed in the massacre of 1622, the undertaking had to be abandoned, and of course all thought of converting and civilizing the savages was given up during the long and relentless war that ensued.
