   With a deep sense of personal integrity and a desire to avoid everything which might impair his absolute independence, Polk declined to accept presents of more than nominal value. Shortly after his inauguration Thomas Lloyd sent him a valuable saddlehorse, but he promptly gave orders that it should be returned to the donor. Another admirer who sent a consignment of wine and other delicacies for the President's table was instructed to send a bill or to take the articles away. It soon became known that he would accept nothing of greater value than a book or a cane. The same rule applied to presents for Mrs. Polk.²⁷ The same scrupulous regard for propriety is shown in his refusal to invest in government securities a certain sum of money belonging to his nephew and ward, Marshall T. Polk.²⁸ His public policies were denounced in unmeasured terms, and his political honesty was frequently impugned, but even his enemies credited him with personal integrity and purity of character. His own personal affairs were characterized by simplicity and frugality. This fact has already been noted in the care with which he guarded against exorbitant charges at the time of his inauguration.²⁹ 1922, Eugene Irving McCormac, “Administration and Patronage”, in James K. Polk: A Political Biography, Berkeley, Cali.: University of California Press, →OCLC, page 331
