There it was--the German system of warfare! These Germans might carry on their war after the most scientifically deadly plan the world has ever known; they might deal out their peculiarly fatal brand of drumhead justice to all civilians who crossed their paths bearing arms; they might burn and waste for punishment; they might lay on a captured city and a whipped province a tribute of foodstuffs and an indemnity of money heavier than any civilized race has ever demanded of the cowed and conquered--might do all these things and more besides--but their common troopers saved the sods of the greensward for replanting and spared the boles of the young shade trees! Next day we again left Brussels, the submissive, and made a much longer excursion under German auspices. And, at length, after much travail, we landed in the German frontier city of Aix-la-Chapelle, where I wrote these lines. There it was, two days after our arrival, that we heard of the fate of Louvain and of that pale little man, the burgomaster, who had survived his crisis of the nerves to die of a German bullet. We wondered what became of the proprietor of the House of the Thousand Columns; and of the young Dutch tutor in the Berlitz School of Languages, who had served us as a guide and interpreter; and of the pretty, gentle little Flemish woman who brought us our meals in her clean, small restaurant round the corner from the Hôtel de Ville; and of the kindly, red-bearded priest at the Church of Saint Jacques, who gave us ripe pears and old wine. I reckon we shall always wonder what became of them, and that we shall never know. I hoped mightily that the American wing of the big Catholic seminary had been spared. It had a stone figure of an American Indian--looking something like Sitting Bull, we thought--over its doors; and that was the only typically American thing we saw in all Louvain. When next I saw Louvain the University was gone and the stone Indian was gone too. CHAPTER V BEING A GUEST OF THE KAISER You know how four of us blundered into the German lines in a taxicab; and how, getting out of German hands after three days and back to Brussels, we undertook, in less than twenty-four hours thereafter, to trail the main forces then shoving steadily southward with no other goal before them but Paris. First by hired hack, as we used to say when writing accounts of funerals down in Paducah, then afoot through the dust, and finally, with an equipment consisting of that butcher's superannuated dogcart, that elderly mare emeritus and those two bicycles, we made our zigzagging way downward through Belgium.
