The air trembled with heat. Only by dodging from the shadow of one big elm to another did he manage to reach the Appian Way--the street given in the university catalogue as Bennie's habitat--alive. As he swung open the little wicket gate he realized with an odd feeling that it was the same house where Hooker had lived when a student, twenty-five years before. "Board" was printed on a yellow, fly-blown card in the corner of the window beside the door. Up there over the porch was the room Bennie had inhabited from '85 to '89. He recalled vividly the night he, Thornton, had put his foot through the lower pane. They had filled up the hole with an old golf stocking. His eyes searched curiously for the pane. There it was, still broken and still stuffed--it couldn't be!--with some colourless material strangely resembling disintegrating worsted. The sun smote him in the back of his neck and drove him to seek the relief of the porch. Had he ever left Cambridge? Wasn't it a dream about his becoming an astronomer and working at the Naval Observatory? And all this stuff about the earth going on the loose? If he opened the door wouldn't he find Bennie with a towel round his head cramming for the "exams"? For a moment he really imagined that he was an undergraduate. Then as he fanned himself with his straw hat he caught, on the silk band across the interior, the words: "Smith's Famous Headwear, Washington, D.C." No, he was really an astronomer. He shuddered in spite of the heat as he pulled the bell knob. What ghosts would its jangle summon? The bell, however, gave no sound; in fact the knob came off in his hand, followed by a foot or so of copper wire. He laughed, gazing at it blankly. No one had ever used the bell in the old days. They had simply kicked open the door and halloed: "O-o-h, Bennie Hooker!" Thornton laid the knob on the piazza and inspected the front of the house. The windows were thick with dust, the "yard" scraggly with weeds. A piece of string held the latch of the gate together. Then automatically, and without intending to do so at all, Thornton turned the handle of the front door, assisting it coincidentally with a gentle kick from his right toe, and found himself in the narrow cabbage-scented hallway. The old, familiar, battered black-walnut hatrack of his student days leaned drunkenly against the wall--Thornton knew one of its back legs was missing--and on the imitation marble slab was a telegram addressed to "Professor Benjamin Hooker." And also, instinctively, Thornton lifted up his adult voice and yelled: "O-o-h, ye-ay! Bennie Hooker!" The volume of his own sound startled him. Instantly he saw the ridiculousness of it--he, the senior astronomer at the Naval Observatory, yelling like that---- "O-o-h, ye-ay!" came in smothered tones from above. Thornton bounded up the stairs, two, three steps at a time, and pounded on the old door over the porch. "Go away!" came back the voice of Bennie Hooker. "Don't want any lunch!"
