Secretary of the Navy Southard commands Lieutenant Mayo, who is in Annapolis, Maryland, to report to Commodore Banon for duty on board the frigate Guerriere. Signed note on verso says an attack of bilious fever kept him from joining the ship. He would have had the rank of first lieutenant.

Southard as Secretary of the Navy asks Lieutenant Mayo to report to Captain James Banon, President of the Naval Court Martial, as a witness in the case of Charles Stewart. Stewart was being accused of convoying a foreign (British) ship into a blockaded port. He was eventually acquitted.

Marked Copy of a Letter to J.D. Elliott, on docket. Written by Lieutenant Commander Mayo as commander of the U.S.S. Grampus to Captain Elliott as commander of the West India Squadron. Half the letter appears to be written in a clerical hand and the last half written and signed by Mayo. References Elliott's orders of 7 September 1830 (see GLC 04604.22) and says he proceeded to the coast off Havana, Cuba on 13 September. He encountered a gale on the way there, taking much water, and anchored in Mantanzas Bay on 21 September. Waited to leave until 2 October because a convoy was gathering. After seeing them through, he crossed through the Straits of Florida, where he encountered another three day gale, and then went into the Caribbean Sea. On 16 October cruised through Caycos Passage and sailed a few days between Cape Maize and St. Domingo. Lists ports he stopped at in St. Domingo. Says there were many American vessels in the ports. Then went off the coast of Columbia, which is a very unsettled country, and assisted American ships like he was instructed. Then went to Port Royal, Jamaica to check on American shipping and to resupply. Put to sea on 14 December and arrived off Cape St. Antonio on 17 December and then hit heavy weather that turned into a hurricane and damaged the sails and rudder. Finally anchored in Pensacola on 25 December. Repairs were being made to the ship and mentions new sails. Says he has received Elliott's orders about sailing in the Gulf of Mexico. Docket is extremely faint on fourth page.
