That the idea of travel as a duty to the State had permeated the
Elizabethans from the courtier to the common sailor is borne out by
contemporary letters of all sorts. Even William Bourne, an innkeeper at
Gravesend, who wrote a hand-book of applied mathematics, called it _The
Treasure for Travellers_[63] and prefaced it with an exhortation in the
style of Turler. In the correspondence of Lord Burghley, Sir Philip
Sidney, Fulke Greville, the Earl of Essex, and Secretary Davison, we see
how seriously the aim of travel was inculcated. Here are the same
reminders to have the welfare of the commonwealth constantly in mind, to
waste no time, to use order and method in observation, and to bring
home, if possible, valuable information. Sidney bewails how much he has
missed for "want of having directed my course to the right end, and by
the right means." But he trusts his brother has imprinted on his mind
"the scope and mark you mean by your pains to shoot at. Your purpose is,
being a gentleman born, to furnish yourself with the knowledge of such
things as may be serviceable to your country."[64]

Davison urges the value of experience, scorning the man who thinks to
fit himself by books: "Our sedentary traveller may pass for a wise man
as long as he converseth either with dead men by reading, or by writing,
with men absent. But let him once enter on the stage of public
employment, and he will soon find, if he can but be sensible of
contempt, that he is unfit for action. For ability to treat with men of
several humours, factions and countries; duly to comply with them, or
stand off, as occasion shall require, is not gotten only by reading of
books, but rather by studying of men: yet this is ever held true. The
best scholar is fittest for a traveller, as being able to make the most
useful observations: experience added to learning makes a perfect
man."[65]

Both Essex and Fulke Greville are full of warnings against superficial
and showy knowledge of foreign countries: "The true end of knowledge is
clearness and strength of judgment, and not ostentation, or ability to
discourse, which I do rather put your Lordship in mind of, because the
most part of noblemen and gentlemen of our time have no other use nor
end of their learning but their table-talk. But God knoweth they have
