"If it be friendship and the love God bids us bear to our enemy, go at
once to the Holy Scriptures, which you can do with a very small amount of
research, and quote no less than the words of God himself: Ego autem dico
vobis: diligite inimicos vestros. If you speak of evil thoughts, turn to
the Gospel: De corde exeunt cogitationes malae. If of the fickleness of
friends, there is Cato, who will give you his distich:

_Donec eris felix multos numerabis amicos,
Tempora si fuerint nubila, solus eris._

"With these and such like bits of Latin they will take you for a
grammarian at all events, and that now-a-days is no small honour and
profit.

"With regard to adding annotations at the end of the book, you may safely
do it in this way. If you mention any giant in your book contrive that it
shall be the giant Goliath, and with this alone, which will cost you
almost nothing, you have a grand note, for you can put--The giant Golias
or Goliath was a Philistine whom the shepherd David slew by a mighty

Kings--in the chapter where you find it written.

"Next, to prove yourself a man of erudition in polite literature and

give you the story of Cacus, for I have it by heart; if with loose women,
there is the Bishop of Mondonedo, who will give you the loan of Lamia,
Laida, and Flora, any reference to whom will bring you great credit; if
with hard-hearted ones, Ovid will furnish you with Medea; if with witches
or enchantresses, Homer has Calypso, and Virgil Circe; if with valiant
captains, Julius Caesar himself will lend you himself in his own
'Commentaries,' and Plutarch will give you a thousand Alexanders. If you
should deal with love, with two ounces you may know of Tuscan you can go
to Leon the Hebrew, who will supply you to your heart's content; or if
you should not care to go to foreign countries you have at home Fonseca's
