Abstract: The site 8Hi426 is located in the 1500 block of 10th Avenue in the Ybor City Historical Preservation District. The site was excavated to salvage data in a controlled archaeological context that could be used to fill in the gaps of the historical record of 19th Century Ybor City. The project goal as to identify the earliest historical occupation levels. In order to expeditiously test the site for subsurface features on a 13-week schedule, the selection of test squares was determined by utilizing a random numbers table. Once features were revealed, two large trenches, A3 and A4, were excavated in areas containing both early and late occupation levels. Of the artifacts recovered, bottle glass was found to be the most suitable for chronometric control. It was subjected to rigorous laboratory analysis utilizing a specially designed codebook of datable bottle attributes. Two thousand and one bottle fragments were given date ranges to which South's (1972) formula date and visual bracketing techniques were applied. These devices produced date ranges for the various stratigraphic levels of the site from which an archaeological model was developed. Site interpretation resulted from comparing this archaeological model with a model of known historical events for Ybor City and the site block. The earliest occupation on the site was between 1886 and 1892. This occupation was confirmed to eight houses on the west end of the block. The excavation revealed that this part of the site was totally removed as fill dirt during the 1973 renewal activity. Area A4 adjacent on the east was shown to have been on the periphery of that initial occupation area. Bottle glass dates indicated that it was earlier that area A3, and the absence of sawdust fill confirmed its relationship to the initial 1886-1892 occupation of the site. Area A3, along 16th Street, was not occupied until after the sawdust was deposited in 1892. No structures were present on A3 until 1932. Despite the extensive renewal damage the earliest occupation levels were identified in all excavated areas.
