By degrees however the good doctor had become so absorbed in the sounds that rushed, now wailing, now jubilant, now tender as a twilight wind, now imperious as the voice of the war-tempest, from the fingers of the raptured boy, that the reading of the first vesper-psalm had commenced while he was yet watching the slow rising index, in the expectation that the organist was about to resume. The voice of his Irish brother-chaplain, Sir Toby Mathews, roused him from his reverie of delight, and as one ashamed he stole away through the door that led from the little organ loft into the minstrel's gallery in the great hall, and so escaped the catholic service, but not the marquis's roasting. Whether the music had any share in the fact that the good man died a good catholic at last, I leave to the speculation of who list. Lady Margaret continued unchangingly kind to Dorothy; and the tireless efforts of the girl to amuse and please poor little Molly, whom the growing warmth of the season seemed to have no power to revive, awoke the deep gratitude of a mother. This, as well as her husband's absences, may have had something to do with the interest she began to take in the engine of which Dorothy had assumed the charge, for which she had always hitherto expressed a special dislike, professing to regard it as her rival in the affections of her husband, but after which she would now inquire as Dorothy's baby, and even listen with patience to her expositions of its wonderful construction and capabilities. Ere long Dorothy had a tale to tell her in connection with the engine, which, although simple and uneventful enough, she yet found considerably more interesting, as involving a good deal of at least mental adventure on the part of her young cousin. One evening, after playing with little Molly for an hour, then putting her to bed and standing by her crib until she fell asleep, Dorothy ran to see to her other baby; for the cistern had fallen rather lower than she thought well, and she was going to fill it. She found Caspar had lighted the furnace as she had requested; she set the engine going, and it soon warmed to its work.
