Caen became an important city under William the Conqueror. Edward III of England captured and pillaged it about the middle of the fourteenth century, at which time it was larger than any city in England, except London. To-day, Caen has less than fifty thousand inhabitants, and is mainly interesting for its art treasures and its memories. Our travel program included Rouen, Amiens, and Beauvais, cathedral cities lying more to the northward. It was at Rouen that we started to trace backward the sacred footsteps of Joan of Arc, saint and savior of France. For it is at Rouen that the pathway ends. When we had visited the great cathedral, whose fairylike façade is one of the most beautiful in the world, we drove to a corner of the old market-place and stopped before a bronze tablet which tells that on this spot on a certain day in May, 1431 (it was the 29th), a young girl who had saved her country from an invading and conquering enemy was burned at the stake. That was five hundred years ago, but time has not dulled the tragedy of the event, its memory of suffering, its humiliation. All those centuries since, the nation that Joan saved has been trying to atone for her death. Streets have been named for her and statues have been set up for her in public squares all over France. There is little in Rouen to-day that Joan saw. The cathedral was there in her time, but she was never permitted to enter it. There is a wall which was a part of the chapel where she had her final hearing before her judges; there are some houses which she must have passed, and there is a tower which belonged to the castle in which she was imprisoned, though it is not certain that it is Joan's tower. There is a small museum in it, and among its treasures we saw the manuscript article "St. Joan of Arc," by Mark Twain, who, in the "Personal Recollections," has left to the world the loveliest picture of that lovely life. It was our purpose to leave Rouen by the Amiens road, but when we got to it and looked up a hill that, about half-way to the zenith, arrived at the sky, we decided to take a road that led off toward Beauvais. We could have climbed that hill well enough, and I wished later we had done so. As it was, we ran along pleasantly during the afternoon, and attended evening services in an old church at Grandvilliers, a place that we had never heard of before, but where we found an inn as good as any in Normandy. It is curious with what exactness fate times its conclusions. If we had left Grandvilliers a few seconds earlier or later, it would have made all the difference, or if I had not pulled up a moment to look at a lovely bit of brookside planted with poplars, or if I had driven the least bit slower or the least bit faster during the first five miles; or--
