Adam Bede

Clearly the rector was not what is called in these days an "earnest" man: he was fonder of church history than of divinity, and had much more insight into men's characters than interest in their opinions; he was neither laborious, nor obviously self-denying, nor very copious in alms-giving, and his theology, you perceive, was lax.†
Chpt 5 *

Tim, thinking slightly of David's vocalization, was impelled to supersede that feeble buzz by a spirited commencement of "Three Merry Mowers," but David was not to be put down so easily, and showed himself capable of a copious crescendo, which was rendering it doubtful whether the rose would not predominate over the mowers, when old Kester, with an entirely unmoved and immovable aspect, suddenly set up a quavering treble—as if he had been an alarum, and the time was come for him to go off.†
Chpt 53
