Different Government Departments have their special flags also. Thus the Transport Service has the blue ensign with a golden anchor, placed horizontally, in the fly, while the Victualling Department has the blue ensign again, but this time as shown in Fig. 98, with two crossed anchors. On the blue ensign of the Board of Trade is found in the fly a white circle, and within this a ship in full sail (see Fig. 105). The Ordnance Department flag, represented in Fig. 108, bears a shield with cannons and cannon balls upon it, while vessels and boats employed on submarine mining service are authorized to carry the blue ensign with--as its special badge--a hand issuing from a mural crown, and grasping a thunderbolt. The Telegraph branch of the Post-Office has a very striking device: a representation of Father Time with his hour glass smashed by lightning. The red ensign is employed by the Custom House and the Excise, in the first case having, as we see in Fig. 107, a golden crown in the fly, and, in the second, a crown and star. The flag of the Admiralty is a very striking one (Fig. 99). This association of the anchor with the Admiralty is a very natural one; we see it not only in our English flag, but in those of France, Italy, Germany, Russia, etc. Our Admiralty flag is hoisted on any ship when the Commissioners {72} of the Admiralty are on board,[53] and it is also hoisted at the fore top-gallant mast of every ship on which the Queen may be on board. Vessels carrying Her Majesty's mail fly on the fore-mast a white burgee, having in its centre a crown, and on one side of it the word "Royal" and on the other "Mail"; the words Royal Mail and the crown being in red on the white field of the flag.
