TO THE REV. WILLIAM UNWIN.
Olney, 1784.
My dear William,—The slice which (you observe) has been taken from the top of the sheet, it lost before I began to write; but, being a part of the paper which is seldom used, I thought it would be pity to discard, or to degrade to meaner purposes, the fair and ample remnant, on account of so immaterial a defect. I therefore have destined it to be the vehicle of a letter, which you will accept as entire, though a lawyer perhaps would, without much difficulty, prove it to be but a fragment. The best recompence I can make you for writing without a frank, is to propose it to you to take your revenge by returning an answer under the same predicament; and the best reason I can give for doing it is the occasion following. In my last I recommended it to you to procure franks for the conveyance of "Tirocinium," dated on a day therein mentioned, and the earliest which at that time I could venture to appoint. It has happened, however, that the poem is finished a month sooner than I expected, and two-thirds of it are at this time fairly transcribed; an accident to which the riders of a Parnassian steed are liable, who never know, before they mount him, at what rate he will choose to travel. If he be indisposed to despatch, it is impossible to accelerate his pace; if otherwise, equally impossible to stop him. Therefore my errand to you at this time is to cancel the former assignation, and to inform you that by whatever means you please, and as soon as you please, the piece in question will be ready to attend you; for, without exerting any extraordinary diligence, I shall have completed the transcript in a week.
The critics will never know that four lines of it were composed while I had a dose of ipecacuanha on my stomach; in short, that I was delivered of the emetic and the verses at the same moment. Knew they this, they would at least allow me to be a poet of singular industry, and confess that I lose no time. I have heard of poets who have found cathartics of sovereign use, when they had occasion to be particularly brilliant. Dryden always used them, and, in commemoration of it, Bayes, in "The Rehearsal," is made to inform the audience, that in a poetical emergency he always had recourse to stewed prunes. But I am the only poet who has dared to reverse the prescription, and whose enterprize, having succeeded to admiration, warrants him to recommend an emetic to all future bards, as the most infallible means of producing a fluent and easy versification.
My love to all your family.
Adieu.
W. C.
