Her Majesty's ships, when at anchor in home ports and roads, hoist their colours at 8 o'clock in the morning from March 25th to September 20th, and the rest of the year an hour later; and on foreign stations, at either of these hours as the commanding officer shall direct; and either abroad or at home they remain flying throughout the day until sunset.[43] When at sea, on passing, meeting, {56} joining or parting from any other of Her Majesty's ships or on falling in with any other ship the flag is hoisted, and also when in sight of land, and especially when passing any fort, battery, lighthouse, or town. When salutes are fired on the occasion of a foreign national festival, such as the birthday of the sovereign, the flag of the nation in question is hoisted at the main during the salute and for such further time as the war ships of such nation are be-flagged, but if none are present, then their flag remains up till sunset. Should a British war vessel arrive at any foreign fortified port, the flag of the foreign nation is hoisted at the main during the exchange of salutes. It is a rank offence for any vessel to fly any ensign or pendant similar to those used in the Royal Navy. It will at once be boarded by any officer of Her Majesty's Service, the offending colours seized, and the vessel reported. The penalty for the offence is a very heavy one. The admiral has as a flag the white flag with the Cross of St. George thereon, Fig. 91, and this must be displayed at the main top-gallant mast-head, since both the vice and rear-admirals are entitled to fly a similar flag, but the former of these displays his from the fore, and the latter from the mizen top-gallant mast-head; it being not the flag alone but the position of it that is distinctive of rank. The commodore's broad pendant is a very similar flag, but it tapers slightly, and is swallow-tailed. The "Naval Discipline Act," better known as "The Articles of War," commences with the true and noble words--"It is on the Navy, under the Good Providence of God, that our Wealth, Prosperity, and Peace depend," and we may trust that the glorious traditions of this great service may be maintained to the full as effectually under the White Ensign as in any former period for the defence of "This royal throne of kings, this scepter'd isle, This earth of majesty, this seat of Mars, This other Eden, demi-paradise; This fortress built by nature for herself, Against infection, and the hand of war; This happy breed of men, this little world; This precious stone set in the silver sea, Which serves it in the office of a wall, Or as a moat defensive to a house, Against the envy of less happier lands; This blessed plot, this earth, this realm, this England."
