Going too long is a cause of abortion as effectual, though not so frequent, as going too short, and holds true especially in the labours of the brain. Well fare the heart of that noble Jesuit 85 who first adventured to confess in print that books must be suited to their several seasons, like dress, and diet, and diversions; and better fare our noble notion for refining upon this among other French modes. I am living fast to see the time when a book that misses its tide shall be neglected as the moon by day, or like mackerel a week after the season. No man has more nicely observed our climate than the bookseller who bought the copy of this work. He knows to a tittle what subjects will best go off in a dry year, and which it is proper to expose foremost when the weather-glass is fallen to much rain. When he had seen this treatise and consulted his almanac upon it, he gave me to understand that he had manifestly considered the two principal things, which were the bulk and the subject, and found it would never take but after a long vacation, and then only in case it should happen to be a hard year for turnips. Upon which I desired to know, considering my urgent necessities, what he thought might be acceptable this month. He looked westward and said, “I doubt we shall have a bit of bad weather. However, if you could prepare some pretty little banter (but not in verse), or a small treatise upon the it would run like wildfire. But if it hold up, I have already hired an author to write something against Dr. Bentley, which I am sure will turn to account.”

At length we agreed upon this expedient, that when a customer comes for one of these, and desires in confidence to know the author, he will tell him very privately as a friend, naming whichever of the wits shall happen to be that week in the vogue, and if Durfey’s last play should be in course, I had as lieve he may be the person as Congreve. This I mention, because I am wonderfully well acquainted with the present relish of courteous readers, and have often observed, with singular pleasure, that a fly driven from a honey-pot will immediately, with very good appetite, alight and finish his meal on an excrement.

I have one word to say upon the subject of profound writers, who are grown very numerous of late, and I know very well the judicious world is resolved to list me in that number. I conceive, therefore, as to the business of being profound, that it is with writers as with wells. A person with good eyes can see to the bottom of the deepest, provided any water be there; and that often when there is nothing in the world at the bottom besides dryness and dirt, though it be but a yard and half under ground, it shall pass, however, for wondrous deep, upon no wiser a reason than because it is wondrous dark.

I am now trying an experiment very frequent among modern authors, which is to write upon nothing, when the subject is utterly exhausted to let the pen still move on; by some called the ghost of wit, delighting to walk after the death of its body. And to say the truth, there seems to be no part of knowledge in fewer hands than that of discerning when to have done. By the time that an author has written out a book, he and his readers are become old acquaintance, and grow very loathe to part; so that I have sometimes known it to be............
