But wishing that they might "show his eyes" the mysterious operations in the little wooden house, however grievous it might be to his feelings, our anxious knight hurried round to the back, where, he took it for granted, there was some means of entrance, as he had seen no officer get in at the window. He was right. There was a small narrow door of planks, with a sentry standing before it, who wore a forbidding face of much importance. And now a gentleman in blue spectacles approached, and nodded to the sentinel, who tapped at the door. The door was unlocked, and the favored man of science entered. Through the closing door, Sir Valentine caught sight of a sort of long, shapeless table, covered with chemical instruments and utensils, in short, an apparatus exciting great curiosity. The door closed, just as Sir Valentine handed up his card to the sentinel. The door was opened again--his card given in; somebody took it, and it seemed to fly over a row of small white porcelain painters' pallets, standing mid-deep in water, and then disappeared, as the door was suddenly closed again. A voice within was heard to say, impatiently, "I really am afraid we can't be disturbed!" "Can't you!" exclaimed Sir Valentine, addressing himself to a servant girl, with a child in her arms, who was trying to get a peep in at the door: "can't you, indeed! What treatment do you call this? Do you think gentlemen would take the trouble to come _down_ here, such a distance, and _up_ here such a height, if they did not expect to see all that could possibly be seen? Is this your duty to the public who pays you? Why should you conceal any thing from me? Am I not a person of sufficient wealth and respectability to be allowed to know of all your doings up here! What brings you here but the public service? Who is your master? tell me that!" "Edward Smith, of Seaford," answered the girl, with an angry face; "but I don't know as it's any business of yours!"
