By the spring of 1621, when the bulk of the college funds had been expended and the lottery was terminated, Sir Edwin's financial resources had become even more skimpy and uncertain. Some projects, such as that for the settlement of Italian glass-workers who were to manufacture pottery and beads for use in the Indian trade, could be financed by subscriptions to a special joint-stock, but this device offered no help in meeting general expenses. As a result, Sandys continued to take certain shortcuts, or perhaps the blame should rest rather on Deputy John Ferrar. In any case, the colonists complained that shipping came out so overloaded with passengers as to invite the epidemic disease with which they usually suffered on landing, and which made of newcomers a useless burden on the colony for some time after their arrival. The deathrate among the colonists continued to be high. The time and energy required to house them, or to feed them, unavoidably forced delay with projects on which Sandys had pinned his chief hopes. He was especially disappointed over the slow progress of agricultural experimentation. Accordingly, when Yeardley's three year term was ended in 1621 and Sir Francis Wyatt was sent as his replacement, Sir Edwin also sent his brother, George Sandys, as appointee to a new office of treasurer. He was given special charge of all projects looking to the development of new staple commodities and was intrusted with the collection of rents, of which the company claimed L1,000 were presently due. These rents, which were to be collected largely from half-share tenants who had migrated within the preceding three years, undoubtedly now constituted the company's main hope for an immediate revenue. Except in a very few instances, no quitrents would be payable until 1625, and so general had been the disappointment experienced so far with special projects that further time would have to be allowed before any return from them could be expected. In short, the company had exhausted its very limited resources in getting Wyatt and George Sandys out to Virginia, and had nothing left but hopes for the future and the anticipation of a small immediate revenue from the rents of its own tenants, most of which had already been assigned to such special charges as the support of public officers in the colony. In London, virtually the only asset left to the company was the will and determination of Sir Edwin Sandys.
