We formed a park in the principal place of the town; there were appointed two sentinels to do duty until the arrival of the gunners who should relieve them and mount a proper guard, and then we were marched off to be shown our various quarters. For before a French regiment arrives at a town others have ridden forward and have marked in chalk upon the doors how many men and how many horses are to be quartered here or there, and my quarters were in a great barn with a very high roof; but my Ancient, upon whom I depended for advice, was quartered in a house, and I was therefore lonely. We groomed our horses, ate our great midday meal, and were free for a couple of hours to wander about the place. It is a garrison, and, at that time, it was full of cavalry, with whom we fraternised; but the experiment was a trifle dangerous, for there is always a risk of a quarrel when regiments meet as there is with two dogs, or two of any other kind of lively things. Then came the evening, and very early, before it was dark, I was asleep in my clothes in some straw, very warm; but I was so lazy that I had not even taken off my belt or sword. And that was the end of the first day's marching. THE SEA-WALL OF THE WASH The town of Wisbeach is very like the town of Boston. It stands upon a river which is very narrow and which curves, and in which there rises and falls a most considerable tide, and which is bounded by slimy wooden sides. Here, as at Boston, the boats cannot turn round; if they come in frontways they have to go out backwards, like Mevagissey bees: an awkward harbour. As I sat there in the White Hart, waiting for steak and onions, I read in a book descriptive of the place that a whale had come to Wisbeach once, and I considered that a whale coming up to Wisbeach on a tide would certainly stay there; not indeed for the delights of the town (of which I say nothing), but because there would be no room to turn round; and a whale cannot swim backwards. The only fish that can swim backwards is an eel. This I have proved by observation, and I challenge any fisherman to deny it. So much for Wisbeach, which stands upon the River Nene or Nen, which is the last of the towns defended by the old sea-wall--which is the third of the Fen ports--the other two being Boston and Lynn, which is served by two lines of railway and which has two stations. Very early next morning, and by one of these stations, another man and I took train to a bridge called Sutton Bridge, where one can cross the River Nen, and where (according to the map) one can see both the sea-walls, the old and the new. It was my plan to walk along the shore of the Wash right across the flats to Lynn, and so at last perhaps comprehend the nature of this curious land. * * * * *
