Through the low country the construction of the canal had evidently been only a matter of dredging, but the multiplication in size and number of the "dumps" as the elevation increased showed that there had been places where digging on an extensive scale had been necessary, especially in connection with the widening and deepening operations. The fact that most of the "dumps" appeared to consist of earth of a very loose and sandy nature, some of them so much so that they had been planted thickly with young trees to prevent their being shifted by the winds, showed that the excavation problem had been a comparatively simple one, more of the nature of that at Suez than Panama, where so much of the way had to be blasted through solid rock.

The looseness of the earth had made it necessary to cut the banks at as low an angle as forty-five degrees in places to prevent caving, and at these points the under-water part of the channel was faced with roughly cut stone to minimize erosion. As this work was only carried a few feet above the surface of the water, it required but slight speed on the part of a large ship to produce a wave high enough to splash over on to the unprotected earth and bring it down in slides. This had doubtless happened very often in the course of the frequent shuttling to and fro of the High Sea Fleet, for the stonework was heavily undermined in many places, with few signs to indicate that much had been done in the way of repairs.

Except in the locks (and even there the concrete was cracking badly in places, particularly at the Kiel end), the canal shows many evidences of the haste of its construction and the serious deterioration it has suffered from heavy use and poor maintenance. It will require much money and labour to put it in proper condition, and neither of these is likely to be over plentiful in Germany for some years to come.

Our first glimpse of Allied prisoners in their "natural habitat" occurred at a point about twenty miles inland from Brunsbüttel, where a new and very lofty railway viaduct was being thrown across the canal. The extensive groups of huts along the bank in the shadow of the half-completed final span of steel looked, from the distance, like ordinary workmen's quarters. As we drew nearer, however, broad belts of barbed wire surrounding those on the right side suggested that they were used as a prison camp even before our glasses had revealed the motley clad group on the bank waving to the Hercules. As the Viceroy came abreast the excited and constantly augmenting crowd, we saw that the uniforms were mostly French and Russian, though there were three or four men in the grey of Italy and at least one with the unmistakable cap of the Serbs. A hulking chap in khaki, whom I was making the object of an especially close scrutiny on the chance that he might be British or American, put an end to doubt by slapping his chest resoundingly and announcing proudly, "Je suis Belge!" From the fact that they were all in good spirits, we took it that they were getting enough to eat and that prospects for repatriation were favourable.

We had quite given up hope of sighting any British when suddenly, from behind a barbed-wire barrier fencing off the last groups of huts, rang out a cry of "'Ow's ol'Blighty?" Sweeping my glass round to the quarter from whence the query came, I focussed on a phiz which, despite its mask of lather, I should have recognized as Cockney just as surely in Korea or Katmandu as on the banks of the Kiel Canal. Waving his brush jauntily in response to the salvo of delighted howls boomed out by the bluejackets lining the starboard rail, he turned back to the little pocket mirror on the side of the hut and resumed his interrupted shave.

"Can you beat that, I ask you?" gasped an American Flying officer who had just clambered up to the bridge. "Here it is the first time that 'Tommy' has seen his country's flag in anywhere from one to four years; and yet, even when he must know he could get a lift home for the asking, all he does is to—go on scraping his face! I say, can you beat it?"

The captain did not reply, but his indulgent grin indicated a sympathetic understanding of "British repressiveness."

But if this particular "Tommy" had been somewhat casual in his greeting, there was nothing to complain of on that score in the reception given us by the next British prisoners we encountered, a few miles further along. The incident—one of the most dramatic of the visit—occurred just after the Hercules had passed under the great railway viaduct which crosses the canal almost midway between Brunsbüttel and Kiel. Wherever practicable, I might explain, all railways have been carried across the canal at a height sufficient to allow even the lofty topmasts of the German warships to pass under by a comfortable margin. Not one of the several viaducts runs much under two hundred feet above the canal, and to attain this height at an easy grade long approaches have been necessary. Some of these—partly steel trestle, partly embankment—stretched beyond eyescope to left and right; but at the viaduct in question the ascent was made by means of two great spiral loops at either end.

A segment of the loop on the left ran close beside the canal in the form of a steep embankment, and as the Hercules glided under the viaduct I saw (we had closed up to within a few hundred yards of her at the time) a long train of passenger cars, drawn by two puffing engines, just beginning the heavy climb. Suddenly I caught the flash of what I took to be a red flag being wildly waved from one of the car windows, and I was just starting to tell the captain that we were about to pass a trainload of revolutionaries when the gust of a mighty cheer swept along the waters to us and set the radio aerials ringing above my head.

"You can't tell me that's a 'Bolshie' yell," observed the American officer decisively. "Nothing but Yanks or Tommies could cough up a roar like that, believe me."
