Encouraged by great public hoopla and imbued with blind faith, Curtis did not foresee the unremitting sacrifices the project would exact from him. He hoped to complete the study in five or six years within a budget of $25,000. In fact, what the New York Herald hailed as "the most gigantic undertaking since the making of the King James edition of the Bible," required for its completion more than thirty years, one and a half million dollars and the assistance of a vast array of patrons, researchers, scientists, editors, master craftsmen, interpreters, sympathetic creditors, tribal elders, and medicine men. Ultimately, the study cost Curtis his family, his financial security and his health. Nevertheless, to the end, he single-mindedly pursued his intense and powerful vision with an extraordinary sense of mission to catalog how Indians lived prior to their contact with the white man. "The passing of every old man or woman means the passing of some tradition, some knowledge of sacred rites possessed by no other;" believed Curtis, "consequently the information that is to be gathered, for the benefit of future generations, respecting the mode of life of one of the great races of mankind, must be collected at once or the opportunity will be lost for all time." His vision was prophetic. By 1930, the year the last volume was published, few visible vestiges remained of the peoples who had once been the continent's sole inhabitants.
