within
these modest limits. So "goe forth, littel boke," and make thyself a
friend among those good husbandmen, who tend the trees of knowledge, and
bring their fruit to the world's market.

Now, reader, one little preliminary parley with you about myself: here
beginneth the trouble of authorship, but it is a trouble causing ease;
ease from thoughts--thoughts--thoughts, which never cease to make one's
head ache till they are fixed on paper; ease from dreams by night and
reveries by day, (thronging up in crowds behind, like Deucalion's
children, or a serried host in front, like Jason's instant army,)
harassing the brain, and struggling for birth, a separate existence, a
definite life; ease, in a cessation of that continuous internal hum of
aerial forget-me-nots, clamouring to be recorded. O, happy unimaginable
vacancy of mind, to whistle as you walk for want of thought! O, mental
holiday, now as impossible to me, as to take a true school-boy's
interest in rounders and prisoner's base! An author's mind--and remember
always, friend, I write in character, so judge not as egotistic vanity
merely the well playing of my _role_--such a mind is not a sheet of
smooth wax, but a magic stone indented with fluttering inscriptions; no
empty tenement, but a barn stored to bursting: it is a painful pressure,
constraining to write for comfort's sake; an appetite craving to be
satisfied, as well as a power to be exerted; an impetus that longs to
get away, rather than a dormant dynamic: thrice have I (let me confess
it) poured forth the alleviating volume as an author, a real
author--real, because for very peace of mind, involuntarily; but still
the vessel fills; still the indigenous crop springs up, choking a better
harvest, seeds of foreign growth; still those Lernaean necks sprout
again, claiming with many mouths to explain, amuse, suggest, and
controvert--to publish invention, and proscribe error. Truly, it were
enviable to be less apprehensive, less retentive; to be fitted with a
colander-mind, like that penal cask which forty-nine Danaides might not
keep from leaking; to be, sometimes at least, suffered for a holiday to
ramble brainless in the paradise of fools. Memory, imagination, zeal,
perceptions of men and things, equally with rank and riches, have often
cost their full price, as many mad have known; they take too much out of
a man--fret, wear, worry him; to be irritable, is the conditional tax
laid of old upon an author's inte
