We have learned, by-the-way, to distinguish the kinds of columns. They were all just Greek to us at first, but we know them now. When we see a column with acanthus leaves on the capital we know it is Corinthian, because we remember the story of the girl of Corinth who planted acanthus on her lover's grave and put a hollow tile around it for protection. Some of the leaves came up outside of the tile by and by, and a young architect came along and got his idea for the Corinthian capital. We know the Ionic, too, because it looks like its initial--a capital "I" with a little curly top--and we say "I" is for Ionic; and we can tell the Doric, because it's the only one that doesn't suggest anything particular to remember it by. It's worth coming to Greece to learn these things. We should never have learned them at home--never in the world. We should not have had any reason for wanting to learn them. We got tired of the Museum--Laura, age fourteen, and I--we were too young and frivolous for such things, though they are wonderful enough, I am sure. But then museums we have always with us, while a day in Athens is a fleeting thing. We wanted to take one of our private side-excursions, and we tried to communicate this fact to the Blue Elephant, who was our driver to-day, as yesterday. It was no light matter. He nodded and smiled when we indicated that we wanted to leave the procession and go it on our own hook, but he did not move. We had already made up our minds that he was subject to fits, or was just plain crazy, for more than once he had suddenly broke away from the party and whirled us around side-streets for a dozen blocks or so to something not down on the programme, rejoining the procession in some unexpected place. But whatever may have induced his impulses then, nothing seemed to stir his ambition for adventure now. I gesticulated and produced money; I summoned the Diplomat to tackle him in his best Xenophan, but it was no use. I got the guide at last, and then there was an exciting harangue that looked as if it might end in blood. I suppose our man thought he wouldn't get his full pay if he deserted the ship crowd. He must have been convinced, finally, for he leaped upon the box, and away we went in a wild race for the shops and by-streets where we had begged the guide to let us go. We had explained that we wanted some bags--some little embroidered bags, such as we had seen earlier in the day when we could not stop. The Blue Elephant understood now and took us to where there were bags--many bags. The whole street was lined with bags and other embroideries, and the Greeks turned out to give us a welcome.
