 adopted until October 4th, 1904. Thus means of communication did not develop beyond the rudimentary stage in both armies. According to all previous experience, telephone lines, as now operated, are practicable in attack only for the purpose of establishing communication down to brigade headquarters.

Until recently, both signal and wig-wag flags were used in Germany. The signal motions are made in an upright position, the Morse code, which is rather difficult to learn, being used. This method of signaling permits communication to be kept up within a radius of 7 km.; moreover, it can be used at night and in combined land and naval operations. The wig-wag signals are easily learned and entirely sufficient for communicating over distances within 3 km.; they also permit information to be despatched rapidly, as abbreviations are employed for certain frequently recurring movements. These signals possess the additional advantage that they can be made by a man while in a prone position. Wig-wag signals are a very effective means of communication and will rarely fail.
