This is particularly the case so long as the sun is in any part of its course even a little in front of the flag, and its light can be reflected. Ou days of sunshine, the sun shining upon a flag of course increases its visibility. The sun shining behind a flag, does not render it more distinct. Those days are best for the transmission of messages in which the atmosphere is clear, but the sun is covered with clouds. The light is then generally diffused. It is on such days that messages have been read at the longest distances. Position Of Signalmen. The position of a signalman, transmitting a message, must be exactly facing the point to which the message is being sent; and this must be the case, whatever the style or character of the signal he is using. Signals, of whatever description, made by the signalman, must also be shown exactly on his right and left, or they will not be clearly displayed to the observer. To determine this exact position, a line, direct to the other station, should be sighted--as over a straight rod, for instance; and a line following thia direction should be marked on the ground in front of the signalman. A line drawn at right angles with this line, should extend on each side of the signalman. If the common signal equipment is to be used, a marking-stake should be driven on the line in front of the flagman, and twelve feet distant from him; and a similar marker should be placed at the same distance on the side lines on either side. All signals must be made with reference t...
