"How many guns does she carry?" if the response should be fifty, the five and the nought flags, Figs. 290 and 296, plus the swallowtail or cornet, as it is technically called, would be hoisted, while the same five-nought signal, without the cornet, would signify "whole fleet change course four points to starboard." If we want to find the English equivalent of some German word, we turn to the German-English half of our dictionary, but if we {131} required the German equivalent of our English word, we should refer to the English-German part of the book, and signal codes are in like manner divided into flag-message and message-flag. By the system we are at present discussing, we should find by referring to the flag-message half of our book, that the three flags 7, 3, 6, meant, "recall cruisers," while 8, 3, 6, signified "sprung a leak." On the other hand, if we wished ourselves to send such an order we should turn to the message-flag half of our code book, and under the heading of "Cruisers," find all the references that could concern the management of such vessels until we presently found "Cruisers, recall--7, 3, 6," and then at once proceed to hoist those particular flags. Only fourteen flags, the ten numerals, the three pennants, and the cornet, suffice for sending many hundreds of messages, but the anonymous author adds, "exclusive of this arrangement, I would propose to have the most current signals in battle made with one flag only, and these should be used on the day of battle only. A similarity between these and the flags used as the numerical signals ought as much as possible to be avoided." Figs. 279, 280, 281, 282, 283, 284, 285, and 286, are illustrations of some of these. The striking design of the rising sun signifies "engage the enemy." Fig. 280 is an order for "close action." Fig. 281 is an instruction to "invert the line of battle by tacking," while Fig. 282 is a direction to "force the enemy's line." It is needless to particularise them all, suffice it to say that each and all are of stirring significance. Many minds were at work on the urgent problem of an adequate system of sea-signalling, and numerous plans, therefore, were suggested. It does not appear that the one we have just referred to as an example of these endeavours to solve the difficulty was ever adopted.
