The importance of stone end scrapers in southern Plains artifact assemblages increased from AD 1200 to the mid-1700s. With Native involvement in the French hide trade, beginning in the early eighteenth century, end scrapers of Florence-A chert underwent a series of changes designed to lessen the costs of hide production (Vehik et al. [2010]. The Plains Hide Trade: French Impact on Wichita Technology and Society. In Across a Great Divide, edited by Laura L. Scheiber and Mark D. Mitchell, pp. 149–173. University of Arizona Press, Tucson). Using data from the earlier study plus more recent analyses of other sites, we reinvestigate earlier ideas and introduce additional thoughts about how end scraper technology changed with Native involvement in the European world economy. Results reaffirm many of the earlier conclusions regarding technological changes in Florence-A chert end scrapers. We also explore unanticipated impacts of site formation processes, complexities of end scraper maintenance, and the ramifications of changing roles in the bison hide trade.

从公元 1200 年到 1700 年代中期，石端刮刀在南部平原神器组合中的重要性增加了。从 18 世纪早期开始，随着土著人参与法国生皮贸易，Florence-A 燧石的末端刮刀经历了一系列旨在降低生皮生产成本的变化（Vehik 等人 [2010]。平原生皮贸易：法国对威奇托技术和社会的影响。跨越大鸿沟，由 Laura L. Scheiber 和 Mark D. Mitchell 编辑，第 149-173 页。亚利桑那大学出版社，图森）。使用来自早期研究的数据以及对其他网站的最新分析，我们重新研究了早期的想法，并介绍了关于末端刮刀技术如何随着 Native 参与欧洲世界经济而发生变化的其他想法。结果再次证实了之前关于 Florence-A 燧石端刮板技术变化的许多结论。我们还探讨了场地形成过程的意外影响、末端刮板维护的复杂性以及野牛皮贸易中角色变化的后果。
