as we danced and sang and megaphoned our way up through their territory came down past Coblenz, their massed horizon blue so much more tangible than our drab brown, their band playing quite other tunes than ours, the doughboys ashore shrilling an occasional greeting to what they half affectionately, half disdainfully call “the poor Frogs.” There was a somewhat different atmosphere aboard these horizon-blue excursion boats than on our own; they seemed to get so much more satisfaction, a contentment almost too deep for words, out of the sight of the _sale Boche_ in manacles. Boatloads of “Tommies” came up to look us over now and then, too, a bit disdainful, as is their nature, but friendly, in their stiff way, for all that, their columns of caps punctuated here and there by the cocked hat of the saucy “Aussies” and the red-banded head-gear of those other un-British Britons from the antipodes who look at first glance so startlingly like our own M. P.’s. Once we were even favored with a call by the sea-dogs whose vigil made this new Watch on the Rhine possible; five “snappy” little submarine-chasers, that had wormed their way up through the canals and rivers of France, anchored down beneath the gigantic monument at the mouth of the Moselle. You have three guesses as to whether or not the Germans looked at them with interest. It was my good fortune to be able to make two excursions into unoccupied Germany while stationed on the Rhine. Those who fancy the sight of an American uniform beyond our lines was like shaking a red tablecloth in a Spanish bull-ring may be surprised to know that these little jaunts were by no means rare. We went not merely in full uniform, quite without camouflage, but in army automobiles and wholly unarmed—and we came back in a condition which a cockney would pronounce in the same way. The first spin was to Düsseldorf, between two of her Sparticist flurries. Not far above Bonn the landscape changed suddenly from American to British khaki, with a boundary post in charge of a circumspect English sergeant between. Below Cologne, with her swarming “Tommies” and her plump and comely girl street-car conductors and “motormen” in their green-banded Boche caps, we passed scores of the apple-cheeked boy recruits England was sending us to take the place of those who were “fed up with it,” and who gazed about them with that wide-eyed interest in every little detail of this strange new land which the traveler would fain keep to the end of his days. It seemed natural to find the British here; one had grown to associate them with the flat, low portions of the country. Far down the river a French post stopped us, but the sentry was so interested in posing before my kodak that he forgot to mention passes, and we were soon speeding on through a narrow horizon-blue belt. The Belgians, who turned the scene to brown again not far beyond, were even less exacting than the _poilus_. At the farther end of the great
