people exchanged, but also the expeditionary gear, from riflestoPierre Cruzatte's violin. The book's contents confirm Rondas main conten tion that the expedition "is no ordinary story" and that itcontinues to attractsus because we can "journeywith a distinctively American com munity" thattravels"through the lands and lives of other communities in aWest already called home by thousands ofNative people" (pp. 47, 48). Gilman relieson decades ofLewis and Clark scholarship,appropriating freelythe insightsshe gleans fromRonda on Indian diplomacy, from geographer JohnL. Allen on cartography,from Paul Cutright on natural science, from William Goetzmann on exploration, and from a dozen other specialistswho have investigatedtheCorps ofDiscovery. Some readers may quarrel with Gilman's characterizations ofmore famous events in the expedition storyor be unsatisfiedwithmany of her conclusions and quick analyses. The note worthy incident in theNez Perce camp in May 1806,forexample,when Lewis angrilyreacted to a criticismofhis choice of cooked dog forfood, Gilman interprets as an ungracious reaction to the explorers' "demands for food,"while other interpreters have stressedLewis's arrogance (p. 261). Gilman seems to accept recent interpreta tionsof the more famous incidenton TwoMedi cine River innorthernMontana in 1806,where Lewis's party killed two Blackfeet, by assigning blame to Lewis forhis unwillingness to let the Indians escapewith his horse. "Had he just lethis horses go,"Gilman writes, "hemight havewalked back to theMissouri and two livesmight have been spared" (p. 287).Most historians consider Lewis and his fellowstohave been ina vulnerable position, andwalking to the Missouri ? a hard two-day ride ? was not a reasonable option. The famous rant against Indian character that Lewis recorded inhis journal at FortClatsop in February 1806Gilman assigns to his "physical revulsion to the coastal Indians," an unlikely source forhis strongcondemnation of allNative peoples inNorth America (p. 252). This is a handsome book, with superb maps and a design that invitesreading. Itcould stand a better index, and there are a few odd mistakes, such as using out-of-date references to theYakama Nation of Washington State,but there isa lotabout the expedition here that will surprise readers. Gilman concludes the book with an important essay on what happened to the journals and collections Lewis and Clark brought back to St. Louis in September 1806. The provenance of Lewis and Clark Expedition material is fascinating, and itunderscores the importance of research on collections in creat ingan exhibition of this size and scope. Readers who want thebasic storyof theLewis and Clark Expedition should stick with thestandardworks, but forexperienced students of the expedition, Lewis and Clark: Across the Divide isamust ad dition to their libraries.
