But, insisted Oliver, why should they have watchmen at all, if not to prevent people from breaking in and disturbing the animals when they were busy with affairs of their own? He meant to stay up there himself some night and see what it was all about; and as he went on to explain how it would be possible to slip up the great stair while the watchmen were at the far end of the long hall, and of the places one could hide if the watchman came along when he wasn't wanted, he said "we" and "us." For, of course, he meant to take Dorcas Jane with him. Where would be the fun of such an adventure if you had it alone? And besides, Oliver had discovered that it was not at all difficult to scare himself with the things he had merely imagined. There were times when Dorcas Jane's frank disbelief was a great comfort to him. Still, he wasn't the sort of boy to be scared before anything has really happened, so when Dorcas Jane suggested that they didn't know what the animals might do to any one who went among them uninvited, he threw it off stoutly. "Pshaw! They can't do anything to us! They're stuffed, Silly!" And to Dorcas Jane, who was by this time completely under the spell of the adventure, it seemed quite likely that the animals should be stuffed so that they couldn't hurt you, and yet not stuffed so much that they couldn't come alive again. It was all of a week before they could begin. There is a kind of feeling you have to have about an adventure without which the affair doesn't come off properly. Anybody who has been much by himself in the woods has had it; or sometime, when you are all alone in the house, all at once there comes a kind of pricking of your skin and a tightness in your chest, not at all unpleasant, and a kind of feeling that the furniture has its eye on you, or that some one behind your shoulder is about to speak, and immediately after that something happens. Or you feel sure it would have happened if somebody hadn't interrupted. Dorcas Jane _never_ had feelings like that. But about a week after Oliver had proposed to her that they spend a part of the night in the long gallery, he was standing in front of the Buffalo case, wondering what actually did happen when a buffalo caught you. Quite unexpectedly, deep behind the big bull's glassy eye, he caught a gleam as of another eye looking at him, meaningly, and with a great deal of friendliness. Oliver felt prickles come out suddenly all over his body, and without quite knowing why, he began to move away from that place, tip-toe and slippingly, like a wild creature in the woods when it does not know who may be about. He told himself it would never do to have the animals come alive without Dorcas Jane, and before all those stupid, staring folk who might come in at any minute and spoil everything.
