As for history, Brown is an inexhaustible mine. I simply "put in my thumb and pull out a plum." But I forgot-there aren't usually plums in mines, are there, except in the prospectuses? Anyhow, it was Brown who made me realise what tremendously interesting things frontiers are. That imaginary line, and then-people, language, costumes, and customs changing as if a fairy had waved a wand. The frontier between France and Spain is a great wide river-on purpose to give us another bridge. Doesn't the name, "Bidassoa," suggest a broad, flowing current running swiftly to the sea?

This time we would have none of the bridge. It was too much bother paying duty on the car, and having a lot of red tape about getting it back again in an hour or two; so we left Balzac, as I have named it, at the last French town and rowed across, on past the first Spanish town, Irun, to a much older, more picturesque one-Fuenterrabia. A particularly handsome boatman wanted to row us, but Brown would do it himself, either to show how well he can manage the oars, or else because the boatman had abnormally long eyelashes, and Brown is rather sick of eyelashes.

Even crossing the river and going down towards the mouth of the stream (with a huge, old ruined castle towering up to mark Fuenterrabia) was quite thrilling, because of the things in history that have happened all around. The estuary runs down to the sea between mountains of wild and awesome shapes. One of them is named after Wellington, because it is supposed to look like his profile lying down, and the other mountains had a chance to see his real profile many times, though I'll be bound his enemies never saw his back. He fought among them-both mountains and enemies, and the latter were some of Napoleon's smartest marshals. He took a whole army across the ford in the Bidassoa, attacked Soult, and chased him all the way up the mountains to the very summit of La Rhune, a great conical peak high up in the sky. Another thing was the Isle des Faisans, right in the middle of the river, where Philippe and Louis the Fourteenth fixed everything up about Louis' Spanish bride. It's the smallest island you ever saw; you wouldn't think there would be room for a whole King of Spain and a King of France to stand on it at the same time, much less sign contracts.

When our boat touched Spanish soil on the beach below Fuenterrabia, two rather ferocious-looking Spaniards in uncomfortable uniforms were waiting for us. They had the air of demanding "your money or your life"; but after all it was only the extraordinarily high, ugly collars of their overcoats which gave them such a formidable appearance. They were custom-house officers guarding the coast, though how they see over those collars to find out what's going on under their noses I don't know. Brown says that soldiers at Madrid have to dress like that in winter to protect themselves from the terrible icy winds, and as Madrid sets the fashion for everything in Spain, the provincial soldiers have to choke themselves in the same way.

It did seem to me that the very air of Spain was different from across the river in France. It was richer and heavier, like incense. It is nice to have an imagination, isn't it, instead of having to potter about leading facts by a string, as if they were dogs? Well, anyway, I am sure people have bigger and blacker eyes in Spain. Just walking up from the beach to the strange old town, I saw two or three peasant women and children with wonderful eyes, like black velvet with stars shining through-eyes that princesses would give fortunes for.

I couldn't help humming "In Old Madrid" under my breath, and I fancied that the salt-smelling breeze brought the snapping of castanets. The sun was hot; but coolness, and rich, tawny shadows swallowed us up in a silent street, crowded with fantastic, beautifully carved, bright-coloured houses, all having balconies, each one more overhanging than the other. Not a soul was to be seen; our footsteps rang on the narrow side-walk, and it seemed rude of our voices when we talked to wake the sleepy silence out of its afternoon nap. But suddenly a handsome young man appeared from a side street, and stopping in the middle of the road, vigorously tinkled a musical bell. Immediately the street became alive. Each house door showed a man; women hung over the gaily-draped balconies; children ran out and clustered round the bell-ringer. He began to speak very fast in guttural Spanish, and we couldn't understand a word he said, though Brown has a smattering of the language-enough to get on with in shops and hotels. When he had finished everyone laughed. All up and down the street came the sound of laughter; deep, bass laughter from the men; contralto laughter from the women. The handsome bell-ringer laughed too, and then vanished as suddenly as he had come. All the life of the quaint street seemed to fade away with him. Slowly the people took themselves indoors; the balconies were empty; the street silent as in a city of the dead. It was like something on the stage; but I suppose it's just a bit of everyday life in Fuenterrabia and old, old Spain.

We went on up to the castle we had seen from the beach, and I turned my eyes away from a big, ugly round building, like a country panorama-place, for that was the bull ring, and the one thing that makes Spain hateful to me. I didn't want even to think of it. The gateway of the palace-for it had been a palace-was splendid-an arch across the street. But on the other side I burst out laughing at a sign, in what was meant to be English, advertising the castle for sale. Capitals were sprinkled about everywhere; the painter had thought they would look pretty, and evidently it was held out as a lure to Britishers and Americans that Charles the Fifth had built it and lived in it. I know Mrs. Washington Potts would love to buy it, and then go home and mention in an absent-minded manner that she'd "acquired a royal palace in Spain as a winter residence." Can't you hear her? But oh, poor palace! It's as airy a mansion now as most castles in Spain, though what's left of its walls is about fifteen feet thick. Still, the glorious view of sea and mountains from the roof would be worth paying for, and wouldn't need thousands of dollars' worth of restoration, like the house.

While we lingered in Fuenterrabia absorbing the atmosphere of old Spain, the time was inconsiderate enough to run away and leave us with only a twisted channel among sand-banks to remember it by. So we took an oddly shaped carriage with a white tasselled awning on it and drove back to Hendaye and our motor-car. But the day was a great success, and I congratulated Brown, which Aunt Mary said it was silly to do, as it is his business to think of everything for us.

Now, as you see by the date of my letter, we're at Pau, to which we came from Biarritz in a delicious morning's run through a pearl-coloured landscape trimmed with blue mountains. As we got into the town the Lightning Conductor, who was driving, whisked us through a few streets, swooped round a large square, and suddenly stopped the car on a broad terrace with an air as though he said, "There! what do you think of that?" I think I gasped. I know I wanted to by way of saluting what must be one of the most wonderful views in the whole world.

We had stopped on a terrace not the least like a street. At one end was an old grey château; then a long line of imposing buildings, almost too graceful to be hotels, which they really were; a church sending a white, soaring spire into the blue sky; an open, shady place, with a statue of Henri Quatre; villas hotels, hotels villas in a sparkling line, with great trees to cut it and throw a blue haze of shadow. That is one side of the terrace. The other is an iron railing, a sudden drop into space, and-the view. Your eyes travel across a park where even in this mid-winter season roses are blooming and date palms are flourishing. Then comes a hurrying river, giving life and music to the landscape; beyond that a wide sweep of hills, with bunches of poplars, and valleys where white villages lie half concealed; and further still, leaping into the sky, the immense line of the Pyrenees, looking to-day so near and sharply outlined that they seemed to be cut out of cardboard. When I was able to speak I told Brown that the very first thing I should do would be to walk to those delectable mountains. "I don't think you could quite manage it, miss," he said, with his quiet smile, "for they are nearly forty miles away." Then we turned round and drove into the courtyard of the hotel, which faces the great view.
