“The woody valleys warm and low,
    The windy summit, wild and high.”

or the closing passage, which Wordsworth alludes to in his sonnet on Dyer—­“Long as the thrush shall pipe on Grongar Hill”: 

    “Grass and flowers Quiet treads
    On the meads and mountain heads. . . 
    And often, by the murmuring rill,
    Hears the thrush while all is still,
    Within the groves of Grongar Hill.”

Wordsworth was attracted by Dyer’s love of “mountain turf” and “spacious airy downs” and “naked Snowdon’s wide, aerial waste.”  The “power of hills” was on him.  Like Wordsworth, too, he moralized his song.  In “Grongar Hill,” the ruined tower suggests the transience of human life:  the rivers running down to the sea are likened to man’s career from birth to death; and Campbell’s couplet,

    “’Tis distance lends enchantment to the view
    And robes the mountain in its azure hue,"[48]

is thought to owe something to Dyer’s

    “As yon summits soft and fair,
    Clad in colors of the air
    Which to those who journey near
    Barren, brown and rough appear,
    Still we tread the same coarse way,
    The present’s still a cloudy day.”

Dyer went to Rome to pursue his art studies and, on his return in 1740, published his “Ruins of Rome” in blank verse.  He was not very successful as a painter, and finally took orders, married, and settled down as a country parson.  In 1757 he published his most ambitious work, “The Fleece,” a poem in blank verse and in four books, descriptive of English wool-growing.  “The subject of ‘The Fleece,’ sir,” pronounced Johnson, “cannot be made poetical.  How can a man write poetically of serges and druggets?” Didactic poetry, in truth, leads too often to ludicrous descents.  Such precepts as “beware the rot,” “enclose, enclose, ye swains,” and

                “-the utility of salt
    Teach thy slow swains”;

with prescriptions for the scab, and advice as to divers kinds of wool combs, are fatal.  A poem of this class has to be made poetical, by dragging in episodes and digressions which do not inhere in the subject itself but are artificially associated with it.  Of such a nature is the loving mention—­quoted in Wordsworth’s sonnet—­of the poet’s native Carmarthenshire

                “-that soft tract
    Of Cambria, deep embayed, Dimetian land,
    By green hills fenced, by Ocean’s murmur lulled.”

Lowell admired the line about the Siberian exiles, met

    “On the dark level of adversity.”

Miltonic reminiscences are frequent in Dyer.  Sabrina is borrowed from “Comus”; “bosky bourn” and “soothest shepherd” from the same; “the light fantastic toe” from “L’Allegro”; “level brine” and “nor taint-worm shall infect the yearning herds,” from “Lycidas”; “audience pure be thy delight, though few,” from “Paradise Lost.”
