“…'' 22 The assertion that ''no bone had been disturbed'' was false because every bone of that young Pocumtuck woman was removed from her grave and boxed up for transport to Smith College. Wilder was considered a ''pioneer'' in developing forensic reconstruction and ''intact excavation'' (Stewart 1982), but his techniques were not precise, and he often focused on aesthetics more than scientific accuracy. When attempting to reconstruct the facial features of the Niantic sunksqua (female chief) Weunquash, for example, he was missing a jawbone; he substituted a ''fairly well-fitting piece from a female white skull,'' and the Providence Sunday Journal proudly announced the result as, ''Indian Princess Restored.''…”

This research examines the disarticulation of Native American funerary assemblages in museum collections and highlights the challenges of identifying them for inventories mandated by the Native American Graves Protection and Repatriation Act (NAGPRA) of 1990. Indigenous objects and human remains from burial sites were routinely subjected to collecting and sorting procedures that stripped them of meaning and context. NAGPRA does not, however, require museums to reassemble sites or locate related materials housed in other institutions. As a result, associated funerary objects and human remains can easily be “lost” in collections and tribal representatives may be unable to find them. This paper samples the evidence from the Middle Connecticut River Valley to illustrate how items were routinely excavated and categorized and proposes a few restorative methodologies for their recovery.

We investigated the accuracy of the basic fusion data for the T(d,n) 4 He, 3 He(d,p) 4 He, T(t,2n) 4 He, D(d,n) 3 He, and D(d,p)T reactions in the 10-to 100 keV bombarding energy region, and assessed the effects of inaccuracies on the design of fusion reactors. The data base for these reactions | particularly the most critical T(d,n) 4 He reaction] rests on 25-year-old experiments whose accuracy (often assumed to be ±5%) has rarely been questioned: yet in all except the d + d reactions, there are significant differences among data set". The errors in the basic data sets may be considerably larger than previously expected, and the effect on design calculations should be significant. Much of the trouble apparently lies in the accuracy of the energy measurements, which are difficult at low energies. Systemptic erroi s of up to 50% are possible in the reactivity values )f the present Tfd.n^He data base. The error, n. me reactivity will propagate proportionately into the errors in fusion probabilities in reactor calculations. 3 He(d,p) 4 He reaction cross sections could be in error by as much as 50% in the low-energy region. The D(d,n) 3 He and D(d,p)T cross sections appear to be well known and consistent. The T(t,2n) 4 He cross section is poorly known and may be subject to large systematic errors. Improved absolute measurements for all the reactions in the low bombarding energy region
