himself that they have been correctly repeated, he hauls them down, with the exception of the flag of manoeuvre, which remains flying at his foremast head. So soon as the signals of the divisional officers have been repeated* by the vessels of their respective divisions, they haul down No. 32 from the main, and hoist, in its stead, general signal 93 (steam seven knots); the flag-ship of the van division adding thereto right vessel's distinguishing pennant over 96 (steam ten knots); and when these last signals have been repeated, the divisional officers haul down everything but the flags of manœuvre. The admiral now understands that all are ready for the manœuvre; and so soon as he desires to execute it, he hauls down the flag of manoeuvre; the divisional officers follow suit, and the manœuvre is commenced instantly, by the vessel on the extreme right of the fleet hoisting their being required to repeat them is, that they may be often in a position where the admiral's signals can be more easily read by them, than by the flag-ship of the van division. * Some officers may think it sufficient for these vessels to hoist here their answering pennants; but, to avoid mistakes, I think every signal of manoeuvre should be repeated by the vessel or vessels to which it is made. the guide flag* and keeping her course at the rate of ten knots an hour, while the rest of the fleet, putting their helms to port simultaneously, come N.E. and reduce their speed to seven knots an hour. * At night a large lantern must take the place of the guide-flag. Whenever any division, squadron or vessel of the fleetother than the reserve-is intended to be released from obedience to a general signal, its distinguishing pennant must be hoisted below the signal.
