POLK, James K., President. Autograph letter signed ("James K Polk") as President, TO TREASURY SECRETARY ROBERT J. WALKER, n.p., 6 January 1847. 1 page, 4to, minor paste stain on left-hand edge, otherwise fine. A letter of introduction for "Mr Lee of N. York." very intelligent gentleman, and request that you will favour him with an interview. I enclose letters from Mr Samuel & Mr Butler introducing Mr Lee to me." A Mississippian, Walker (1801-1869) proved one of Polk's most competent cabinet officers. During the Mexican War he raised private funds, established the independent treasury, and is perhaps best remembered for the Walker Tariff of 1846, which curbed import duties, reduced tariff rates and instituted the practice of storing imported goods in warehouses pending payment of duties.
