Which of the five senses does the third stanza concentrate on? List examples.

William Wordsworth's 1849 poem pays respect to the steady habits of a village blacksmith, a widower who works hard, practices faith, and lives simply. The third stanza has many appeals to the reader's sense of hearing.

"Week in, week out, from morn till night,You can hear his bellows blow;You can hear him swing his heavy sledge,With measured beat and slow,Like a sexton ringing the village bell,When the evening sun is low."

A bellows is a tool that produces air to feed a fire. When it is operated, it produces a whooshing sound. In using it, the fire would respond by flaring, which would also produce sound.
The sledge that is mentioned in line three is a sledge hammer, a tool composed of a wooden handle and a blunt iron head. A blacksmith uses a sledge hammer to shape hot metal by pounding it on an iron anvil. The sound that it produces is rhythmic and clamorous as metal hits metal. It is a clanging sound. The poem's speaker describes the sound as slow, meaning that the blacksmith pounds slowly and methodically. Using a simile, he compares it to the ringing of a church bell for evening prayers.
