It is customary also for the airships to carry, in addition to explosive and incendiary bombs, others which on being dropped throw out a light and thereby help to indicate to the vessel above the object which it is desired to aim at. Probably some of the bombs which were thrown in Norfolk were of this character. It is understood that all idea of carrying an armament on top of the Zeppelins has now been abandoned, and it is obvious that if searchlight equipment or guns of any sort were carried the useful weight for bombs would have to be reduced unless the range of action was diminished. It will have been noticed that the Zeppelins which came on Tuesday appear to have been anxious to get back before daylight, which looks as if they expected to be attacked if they were seen, as it is fairly certain they would have been. Assuming the raid of Tuesday to have been in the nature of a trial trip, it is rather curious that it was not made before. Apparently the Zeppelins can only trust themselves to make a raid of this description in very favorable circumstances. Strong winds, heavy rain, or even a damp atmosphere are all hindrances to be considered. That there will be more raids is fairly certain, but there cannot be many nights when the Germans can hope to have a repetition of the conditions of weather and darkness which prevailed this week. It should be possible, more or less, to ascertain the nights in every month in which, given other suitable circumstances, raids are likely to be made. In view of the probability that the attacks made by British aviators on the Zeppelin bases at Düsseldorf and Friedrichshafen caused a delay in the German plans for making this week's attack, it would appear that the most effective antidote would be a repetition of such legitimate operations. JULIUS CAESAR ON THE AISNE [From The New Yorker Herold (Morgenblatt.)] It has repeatedly been pointed out that 2000 years ago Julius Caesar fought on the battlegrounds of the Aisne, which are now the location of the fierce fighting between the Germans and the French. It is probably less known, however, that in this present war Caesar's "Commentarii de Bello Gallico" are used by French officers as a practical text book on strategy. The war correspondent of the Corriere della Serra reports this some what astonishing fact. A few weeks ago he visited his friend, a commanding Colonel of a French regiment, in his trench, which was furnished with bare necessities only. In a corner on a small table lay the open volume of "Commentarii Caesaris," which the visitor took into his hand out of curiosity in order to see what passage the Colonel had just been reading. There he found the description of the fight against the Remer, who, at that time, lived in the neighborhood of the present city of Rheims. Principally with the aid of his Numidian troops, Caesar at that time had prevented the Remer from crossing the River Axona, today called the Aisne.
