"I had in this year a great deal of troublesome and on the whole unpleasant correspondence with the Admiralty about the correction of the compass in iron ships. I naturally expected some acknowledgment of an important service rendered to Navigation: but the Admiralty peremptorily refused it. My account of the Experiments &c. for the Royal Society is dated April 9th. The general success of the undertaking soon became notorious, and (as I understood) led immediately to extensive building of iron ships: and it led also to applications to me for correction of compasses. On Jan. 9th I was addressed in reference to the Royal Sovereign and Royal George at Liverpool; July 18th the Orwell; May 11th two Russian ships built on the Thames; Sept. 4th the ships of the Lancaster Company. "I had much work in connection with the Cape of Good Hope Observatory, chiefly relating to the instrumental equipment and to the geodetical work. As it was considered advisable that any base measured in the Cape Colony should be measured with compensation bars, I applied to Major Jervis for the loan of those belonging to the East Indian Survey, but he positively refused to lend them. On Jan. 20th I applied to Col. Colby for the compensation bars of the British Survey, and he immediately assented to lending them. Col. Colby had suggested to the Ordnance Department that Capt. Henderson and several sappers should be sent to use the measuring bars, and it was so arranged. It still appeared desirable to have the command of some soldiers from the Garrison of Cape Town, and this matter was soon arranged with the military authorities by the Admiralty.
