A public service announcement

The irrepressible Elinor Dashwood, who has the great good sense to love the Autumn, asks after a John Donne quote. I'm glad to report having found it:
"In Heaven it is always Autumne; His mercies are ever in their maturity." It comes from a sermon, not a poem, which likely led to Miss Dashwood/Dame Cacciaguida's difficulty in finding it. The whole piece is worth a read, despite its typos.
