is grandly altered into
"Through the black night that sits immense around."
Thus, in Spring, Thomson had merely written
"Whose aged oaks and venerable gloom
Invite the noisy rooks;"
but his corrector alters and extends the passage into
"Whose aged elms and venerable oaks
Invite the rooks, who high amid the boughs
In early spring their airy city build,
And caw with ceaseless clamour."
