GERMAN GREAT HEADQUARTERS IN FRANCE, Dec. 9.--I have just eaten my way along the German front in France, for a second visit to the German Great Headquarters. This week's lunch and dinner "bag" included Gen. von Heeringen, "the Victor of Saarburg"; Gen. von Emmich, "the Conqueror of Liege"; Gen. von Zwehl, "the Hero of Maubeuge"; Gen. von Wild, the new Quartermaster General, who before his appointment fought a twenty-round draw with the English at Ypres, though he thinks he won on points, and hosts of coming champions. It is literally necessary for an American correspondent on this side of the fence to eat his way to the firing line and back again, for the German afield is as hospitable as the tented Arab, and, thanks to their wonderful field telephone service, they "have you." The A.O.K. (Armee Ober Kommando) telephones to the Corps Kommando that you are on the way, the Corps Kommando relays the news to the Division Staff, the Division Staff rings up the Regimental Commander, who 'phones the Battalion or Battery Chief. To reach the firing line you have to run the gauntlet of anywhere from three to six meals, and if you happen to be one of those "amazing Americans" and insist on being shown to an orchestra seat in the first trench, you will be sure to find some sort of a table spread for you in the very shadow of death, for their habit of hospitality is fireproof. But while robbing war corresponding of all its old-time romance, the German, gastronomic way has the great advantage of giving you the maximum of information in the minimum of time and of letting you meet the masters of modern warfare, the men who have done big things, under ideal conditions, for over after-dinner coffee and cigars you can and will--if you are an American--ask the most imprudent questions with the certainty of getting a good-natured and courteous answer.
