you will find them in Lamberti, till the
year 1715, and after that time in Rousset's 'Recueil'.

I do not mean that you should plod hours together in researches of this
kind: no, you may employ your time more usefully: but I mean, that you
should make the most of the moments you do employ, by method, and the
pursuit of one single object at a time; nor should I call it a digression
from that object, if when you meet with clashing and jarring pretensions
of different princes to the same thing, you had immediately recourse to
other books, in which those several pretensions were clearly stated; on
the contrary, that is the only way of remembering those contested rights
and claims: for, were a man to read 'tout de suite', Schwederus's
'Theatrum Pretensionum', he would only be confounded by the variety, and
remember none of them; whereas, by examining them occasionally, as they
happen to occur, either in the course of your historical reading, or as
they are agitated in your own times, you will retain them, by connecting
them with those historical facts which occasioned your inquiry. For
example, had you read, in the course of two or three folios of
Pretensions, those, among others, of the two Kings of England and Prussia
to Oost Frise, it is impossible, that you should have remembered them;
but now, that they are become the debated object at the Diet at Ratisbon,
and the topic of all political conversations, if you consult both books
and persons concerning them, and inform yourself thoroughly, you will
never forget them as long as you live. You will hear a great deal of them
ow one side, at Hanover, and as much on the other side, afterward, at
Berlin: hear both sides, and form your own opinion; but dispute with
neither.

Letters from foreign ministers to their courts, and from their courts to
them, are, if genuine, the best and most authentic records you can read,
as far as they go. Cardinal d'Ossat's, President Jeanin's, D'Estrade's,
Sir William Temple's, will not only inform your mind, but form your
style; which, in letters of business, should be very plain and simple,
but, at the same time, exceedingly clear, correct, and pure.

All that I have said may be reduced to these two or three plain
principles: 1st, That you should now read very little, but converse a
great deal; 2d, To read no useless, unprofitable books; and 3d, That
those which you do read, may all tend to a certain object, and be
relative to, and consequent
