The mural decorations of the dug-outs are also worthy of more than superficial notice, as they often reflect the interests or character of the occupants. The pretty faces of ‘Harrison Fisher,’ ‘Philip Boileau,’ and other girls smile at one from the walls of many of these abodes, and Bairnsfather pictures caricaturing the very scenes of the life going on outside are to be seen everywhere. Grim pictures of the war from the pen of Matania and other artists may be found in the dug-outs of some of the more serious-minded, while others show their hankering after yachting, shooting, or racing. A total of many thousands of square feet of wall space must be taken up by cuttings from the ‘Vie Parisienne,’ and in many cases, more especially in the French lines, the occupant himself has been responsible for the pictures and designs in his quarters. The enemy, too, has his notice boards, and some of them are written and stuck up on the parapet for our benefit or otherwise. Insulting remarks are not infrequently displayed in this way. Sometimes he brags about some big gun he is bringing up to shell our back billets with, sometimes we are told that he is quite ready for our attack on such and such a date—information which is usually incorrect. The German notice with which continental travellers were, perhaps, most familiar before the war is conspicuous by its absence—NICHT HINAUSLEHNEN; it would, however, be a most appropriate warning for visitors to the trenches! On captured ground some of the German notices and signs still remain, but many have been replaced. A spot which had once been used by the Germans as a dump for stores is now labelled—FRITZ’S DUMP—UNDER ENTIRELY NEW MANAGEMENT! Those who have their being in the observation posts are particularly shy of visitors and—NO ADMITTANCE—placards of all descriptions greet one at their entrances. In this the observers show their wisdom, for the inexperienced may unwittingly give away the position to the enemy. It is not always necessary to show oneself to do this. A few puffs of smoke from a pipe, or the use of a telescope without a protecting cowl to keep the sun from reflecting in it, may bring about destruction. I remember a careless Hun drawing attention to an otherwise well concealed post by flourishing an unshaded telescope in the sunlight! A comic relief to a scene of havoc and destruction in an observation post was once presented to me by a portion of a printed notice giving instructions as to what observers were to look out for and report. The post had been spotted, and after the expenditure of many rounds, the enemy had at last obtained a direct hit. Crawling in through the débris to report the damage, I was confronted by a broken beam to which item 2 of the notice was still adhering—WHAT ARE THE GERMAN GUNS FIRING AT? Would that the answer had been less easy to guess! _IN SALONICA: KING CONSTANTINE’S FÊTE._
