【正文】 And I added: 39。I think she39。s awfully brave, too. It must have hurt a lot.39。 39。Will you keep a secret — an important secret — for her sake?39。 she asked. 39。Yes — of course,39。 I agreed, but a little uncertain in my tone for not realizing what the secret was. 39。 You — you saw her foot?39。 she said, looking steadily into my face. 39。 Her — toes?39。 I nodded. 39。Yes,39。 I said again. 39。Well, that is the secret, David. Nobody else must know about that. You are the only person who does, except her father and m e. Nobody else must know. Nobody at all — not ever.39。 39。No,39。 I agreed, and nodded seriously again. There was a pause — at least, her voice paused, but her thoughts went on, as if 39。 nobody 39。 and 39。 not ever39。 were making desolate, unhappy echoes there. Then that changed, and she became tense and fierce and afraid inside. It was no good thinking back to her, so I tried clumsily to emphasize in words that I had meant what I said. 39。 Never — not anybody at all,39。 I assured her earnestly. 39。 It39。s very, very important,39。 she insisted. 39。 How can I explain to you?39。 But she didn39。t really need to explain. Her urgent, tightstrung feeling of the importance was very plain. Her words were far less FOR months the great pleasure excursion to Europe and the Holy Land was chatted about in the newspapers everywhere in America and discussed at countless firesides. It was a novelty in the way of excursions its like had not been thought of before, and it pelled that interest which attractive novelties always mand. It was to be a piic on a gigantic scale. The participants in it, instead of freighting an ungainly steam ferry boat with youth and beauty and pies and doughnuts, and paddling up some obscure creek to disembark upon a grassy lawn and wear themselves out with a long summer day39。s laborious frolicking under the impression that it was fun, were to sail away in a great steamship with flags flying and cannon pealing, and take a royal holiday beyond the broad ocean in many a strange clime and in many a land renowned in history! They were to sail for months over the breezy Atlantic and the sunny Mediterranean。 they were to scamper about the decks by day, filling the ship with shouts and laughter or read novels and poetry in the shade of the smokestacks, or watch for the jelly fish and the nautilus over the side, and the shark, the whale, and other strange monsters of the deep。 and at night they were to dance in the open air, on the upper deck, in the midst of a ballroom that stretched from horizon to horizon, and was domed by the bending heavens and lighted by no meaner lamps than the stars and the magnificent moondance, and promenade, and smoke, and sing, and make love, and search the skies for constellations that never associate with the Big Dipper they 20 were so tired of。 and they were to see the ships of twenty navies the customs and costumes of twenty curious peoples the great cities of half a world they were to hobnob with nobility and hold friendly converse with kings and princes, grand moguls, and the anointed lords of mighty empires! It was a brave conception。 it was the offspring of a most ingenious brain. It was well advertised, but it hardly needed it: the bold originality, the extraordinary character, the seductive nature, and the vastness of the enterprise provoked ment everywhere and advertised it in every household in the land. Who could read the program of the excursion without longing to make one of the party? I will insert it here. It is almost as good as a map. As a text for this book, nothing could be better: EXCURSION TO THE HOLY LAND, EGYPT, THE CRIMEA, GREECE, AND INTERMEDIATE POINTS OF INTEREST. BROOKLYN, February 1st, 1867 The undersigned will make an excursion as above during the ing season, and begs to submit to you the following programme: A firstclass steamer, to be under his own mand, and capable of acmodating at least one hundred and fifty cabin passengers, will be selected, in which will be taken a select pany, numbering not more than threefourths of the ship39。s capacity. There is good reason to believe that this pany can be easily made up in this immediate vicinity, of mutual friends and acquaintances. The steamer will be provided with every necessary fort, including library and musical instruments. An experienced physician will be on board. Leaving New York about June 1st, a middle and pleasant route will be taken across the Atlantic, and passing through the group of Azores, St. Michael will be reached in about ten days. A day or two will be spent here, enjoying the fruit and wild scenery of these islands, and the voyage continued, and Gibraltar reached in three or four days. A day or two will be spent here in looking over the wonderful subterraneous fortifications, permission to visit these galleries being readily obtained. From Gibraltar, running along the coasts of Spain and France, Marseilles will be reached in three days. Here ample time will be given not only to look over the city, which was founded six hundred years before the Christian era, and its artificial port, the finest of the kind in the Mediterranean, but to visit Paris during the Great Exhibition。 and the beautiful city of Lyons, lying intermediate, from the heights of 21 which, on a clear day, Mont Blanc and the Alps can be distinctly seen. Passengers who may wish to extend the time at Paris
