The Hazard Family Letters 1832-1950
July 14, 1837 Invoice for the Vicksburg - Captain Woodhouse in Command
to Roland G. Hazard (Peace Dale Manufacturing Co) Peace Dale, RI 
(Scroll Down for Background Information) 

July 15, 1837 New York cancel - 18^3/4 Rate Marking
(Looks like 18^1/2 - See 1836 Thomas R Hazard Letter for explanation)

The Postal Act of March 3, 1825, (effective May 1, 1825) increased the zone rate for 150 to 400 miles to 18^3/4 cents. Previously, (Act of April 9, 1816) the rate was set at 18^1/2 cents. 

The Letter contains Eleven Invoices on one multi-invoice form - Captain Woodhouse on board the sailing ship Vicksburg at New York to Roland G. Hazard - Peace Dale Mills in Peace Dale, Rhode Island. All eleven invoices are for textile merchandise listed as bales to be delivered in New Orleans, Louisiana. The invoices are on two sheets, however I believe it was originally one sheet that has been separated, as it was sent at the single sheet rate of 18^3/4 cents.
