They had chosen the Hoosac Tunnel route to Niagara, because, as Basil said, their experience of travel had never yet included a very long tunnel, and it would be a signal fact by which the children would always remember the journey, if nothing else remarkable happened to impress it upon them. Indeed, they were so much concerned in it that they began to ask when they should come to this tunnel, even before they began to ask for lunch; and the long time before they reached it was not perceptibly shortened by Tom's quarter-hourly consultations of his father's watch. It scarcely seemed to Basil and Isabel that their fellow-passengers were so interesting as their fellow passengers used to be in their former days of travel. They were soberly dressed, and were all of a middle-aged sobriety of deportment, from which nothing salient offered itself for conjecture or speculation; and there was little within the car to take their minds from the brilliant young world that flashed and sang by them outside. The belated spring had ripened, with its frequent rains, into the perfection of early summer; the grass was thicker and the foliage denser than they had ever seen it before; and when they had run out into the hills beyond Fitchburg, they saw the laurel in bloom. It was everywhere in the woods, lurking like drifts among the underbrush, and overflowing the tops, and stealing down the hollows, of the railroad embankments; a snow of blossom flushed with a mist of pink. Its shy, wild beauty ceased whenever the train stopped, but the orioles made up for its absence with their singing in the village trees about the stations; and though Fitchburg and Ayer's Junction and Athol are not names that invoke historical or romantic associations, the hearts of Basil and Isabel began to stir with the joy of travel before they had passed these points. At the first Basil got out to buy the cold chicken which had been commanded, and he recognized in the keeper of the railroad restaurant their former conductor, who had been warned by the spirits never to travel without a flower of some sort carried between his lips, and who had preserved his own life and the lives of his passengers for many years by this simple device. His presence lent the sponge cake and rhubarb pie and baked beans a supernatural interest, and reconciled Basil to the toughness of the athletic bird which the mystical ex-partner of fate had sold him; he justly reflected that if he had heard the story of the restaurateur's superstition in a foreign land, or another time, he would have found in it a certain poetry. It was this willingness to find poetry in things around them that kept his life and Isabel's fresh, and they taught their children the secret of their elixir. To be sure, it was only a genre poetry, but it was such as has always inspired English art and song; and now the whole family enjoyed, as if it had been a passage from Goldsmith or Wordsworth, the flying sentiment of the railroad side.
