Capt Doble,
It being represented to the Board, that the Prisoners confin'd on Board the Guard Ship under your Command are subject to great inconvenience, & distress by being so closely & early shut down under Deck, you are in future to permit them to be on Deck if they choose it till 10, o'clock in the Evening, & to leave the Hatches open when the Heat of the Weather may make it necessary, or they may desire it.
By order of the Board Saml Phps Savage, Prest
