Read it through once

MRS. HARDCASTLE. How’s this?--(Reads.) “Dear ’Squire, I’m now waiting for Miss Neville, with a post-chaise and pair, at the bottom of the garden, but I find my horses yet unable to perform the journey. I expect you’ll assist us with a pair of fresh horses, as you promised. Dispatch is necessary, as the HAG (ay, the hag), your mother, will otherwise suspect us! Yours, Hastings.” Grant me patience. I shall run distracted! My rage chokes me.
