He kissed her quickly and hurried away, and his form was soon lost in the bend of the street. How dark it was under the trees! The increasing dull daylight brightened everything save the darkness under the trees; nothing could relieve that. What if he should go into it never to return, as he had intended the night they were married! No, no, no; she wrung her hands at that thought, and ran towards the door, as if intending to pursue him and bring him back before he could enter it. But Allan was strong and trusty, and he would come back to laugh at her childish fears as she took his dripping garments at the close of the day, and listened to an account of his adventures,--no fear of that. A half hour later she saw a boat with a single rower put out from the town, and make slow headway against the strong current to the other shore. Was he going alone? It was not dangerous; she persuaded herself of that, but she thought it must be very lonesome rowing about in such a flood; and he should not go out again, for he would do anything she wished, and she would ask it as a favor. Why had she neglected to think of this, and ask him to go with others? But it was too late now, for the rower soon reached the line of trees he had pointed out to her from the window, waved his white handkerchief, which looked like a signal of danger, and disappeared into the shadow. CHAPTER XIX. MR. WHITTLE MAKES A CONFESSION. The first rays of the bad morning, as it looked in at Mr. Whittle's window, found that worthy busily engaged in cleaning and scouring his gun. It was not yet his bedtime, for of late he spent all of every night, instead of part of it, in prowling about--bent on mischief, _he_ said, but Silas Davy knew that Tug had a fierce desire to protect Allan Dorris, for whom he had taken such a strange fancy, from harm; and that night after night, whether the weather was good or bad, his friend kept watch around The Locks, carrying his gun in readiness for instant use. Silas usually kept him company until he became sleepy, and knew that he must return in order to keep awake and attend to his work the next day; but Tug, who slept during the day, seldom deserted his post. He may have left his beat occasionally for an hour or two, but only to creep carefully up into the hills back of the house, where he crouched and listened beside the paths, and then crept back again. A good many times he walked down to the hotel, always choosing an hour when he knew Silas would be alone in the kitchen, on which occasions he never failed to take a shot with his eyes up the alleys, and into all the dark places; but he did not remain long, so that almost every night, when Silas went to bed, he had the satisfaction of knowing that if the shadow should attempt to harm Allan Dorris, there would be an explosion loud enough to alarm the town.
