d foundation upon which you must both stand and rise. A
man's moral character is a more delicate thing than a woman's reputation
of chastity. A slip or two may possibly be forgiven her, and her
character may be clarified by subsequent and continued good conduct: but
a man's moral character once tainted is irreparably destroyed. The second
was, that you had acquired a most correct and extensive knowledge of
foreign affairs, such as the history, the treaties, and the forms of
government of the several countries of Europe. This sort of knowledge,
little attended to here, will make you not only useful, but necessary, in
your future destination, and carry you very far. He added that you wanted
from hence some books relative to our laws and constitution, our
colonies, and our commerce; of which you know less than of those of any
other part of Europe. I will send you what short books I can find of that
sort, to give you a general notion of those things: but you cannot have
time to go into their depths at present--you cannot now engage with new
folios; you and I will refer the constitutional part of this country to
our meeting here, when we will enter seriously into it, and read the
necessary books together. In the meantime, go on in the course you are
in, of foreign matters; converse with ministers and others of every
country, watch the transactions of every court, and endeavor to trace

exercises, will be all that you can possibly have time for at Paris; for
you must allow a great deal for company and pleasures: it is they that
must give you those manners, that address, that 'tournure' of the 'beau
monde', which will qualify you for your future destination. You must
first please, in order to get the confidence, and consequently the
secrets, of the courts and ministers for whom and with whom you
negotiate.

I will send you by the first opportunity a short book written by Lord
Bolingbroke, under the name of Sir John Oldcastle, containing remarks
upon the history of England; which will give you a clear general notion
of our constitution, and which will serve you, at the same time, like all
Lord Bolingbroke's works, for a model of eloquence and style. I will also
send you Sir Josiah Childe's little book upon trade, which may properly
be called the "Commercial Grammar." He lays down the true principles of
commerce, and his conclusions from them are generally v
