Many an old deserted room in the high-pitched roof was given over to these inoffensive, man-loving birds. Hundreds of nests, some in good condition, others deserted and out of repair, clung to old beams, rafters and wainscots. A steady sound of fluttering and juvenile chirping issued through the closed doors, contrasting with the silence of the long stone corridor, whilst parent birds whirled gracefully in and out through the dusty open windows, or poised themselves on the warm shingles of the roof. The grandest, most comfortable quarters were afforded in a large unused chamber occupying the front gable; and, curiously enough, either in reality or fancy, we could not help observing that whilst the various members of the community lived fraternally together, there still seemed to be a distinction between the swallows who dwelt in these spacious quarters and those who lived in humbler lodgings behind. You might imagine that the dwellers in front had become rich through trade, for they suffered no more from the perpetual booming of the great house-clock above their heads, or from the ever-moving pendulum which pulsated like a living thing in their midst, than a manufacturer from the constant sound of his busy steam-engines and rattling machinery. This swallow domain soon became known as Castle Clock-Tower, and the chief inmates as the Herr and Frau von Schwalbe and family, whilst, oddly enough, if it was our daily pleasure to watch them, they showed an equal curiosity and interest in us. I do not know whether they considered that the fly-papers in our sitting-room might be thwarting the designs of Providence on their behalf, but we had hardly begun using them for the destruction of the flies, when Herr von Schwalbe flew down from his castle through the open window, apparently sent as a deputy to remonstrate with us on this reckless waste of their legitimate game. He fluttered about, glancing at the dead bodies strewn on the floor; then, taking his post on the top of a picture hanging on the wall, remained several hours, drawing his own deductions, but always too timid to raise a complaint. In vain we tried to encourage him, to induce him to leave his lofty position: the lonely visitant remained timidly stationary, so that night came on before he ventured his flight.
