traffic on the line, and usually occupies from ten to twenty-four hours to accomplish the journey from the front to Boulogne or Le Havre, as the case may be; sometimes even longer in making the return journey. French trains, at any rate in war-time, are anything but rapid, and to get to one place from another by train is not always so easy a matter as might at first appear. * * * * * The R.S.O. is responsible for the issue of all rations and forage at railhead, whether from the supply trains or from the railhead "dump" or "detail" trucks, while the R.O.O. deals with the classification and return to the Base of all unserviceable and worn out material classed as Ordnance Stores, which term includes such items as used shell cases, rifles, boots, clothing, horseshoes, saddlery, and various equipment. The A.M.P.O. receives and distributes the various boxes of presents, luxuries, and so forth, sent by friends at home through the M.F.O., Southampton, a task more arduous than it may appear, particularly about Christmas-time, and also dispatches home surplus personal and deceased officers’ kits, etc. At each railhead there is to be found also a field post office. I need hardly add that from it His Majesty’s mails, always so eagerly awaited by all of us, are distributed and loaded on to postal lorries of the Supply Column allotted for the purpose, which take the mails on to the units of the Division. The field post offices are in charge of the R.E.’s. What a wonderful corps the Sappers are! Their versatility and multifarious duties are truly remarkable, varying as they do from "tunnelling" and the administration of asphyxiating gases to the Huns from our front line trenches to the maintenance of telephone wires and the running of field post offices. One of the excitements of railhead is the passing through of convoys of German prisoners _en route_ to internment camps. On one occasion I happened to be at Merville and saw a party of prisoners marched into the railhead yard, where they were to entrain; their escort consisted of some Gurkhas, whom they looked on with evident signs of alarm and suspicion. The R.T.O. happened to be able to speak German, and very soon formed the prisoners up in two ranks and marched them to the train, giving his words of command in their own language, greatly, it need scarcely be added, to their surprise. On such occasions as the entraining of German prisoners, "souvenirs" are in great demand, in the shape of German uniform buttons and helmets, though the latter are more uncommon than was formerly the case. This word "souvenir," which is frequently put in the form of a request by the inhabitants to English soldiers, appears to cover a variety of articles, from an empty shell case to a full tin of "bully." It is the recognized custom within the war zone for every one to ask every one else for a souvenir.
