ly duty, but likewise great obligations for
her care and tenderness; and, consequently, cannot take too many
opportunities of showing your gratitude.

I am impatient to receive your account of Dresden, and likewise your
answers to the many questions that I asked you.

Adieu for this time, and God bless you!

LETTER XL

LONDON, May 27, O. S. 1748.

DEAR BOY: This and the two next years make so important a period of your
life, that I cannot help repeating to you my exhortations, my commands,
and (what I hope will be still more prevailing with you than either) my
earnest entreaties, to employ them well. Every moment that you now lose,
is so much character and advantage lost; as, on the other hand, every
moment that you now employ usefully, is so much time wisely laid out, at
most prodigious interest. These two years must lay the foundations of all
the knowledge that you will ever have; you may build upon them afterward
as much as you please, but it will be too late to lay any new ones. Let
me beg of you, therefore, to grudge no labor nor pains to acquire, in
time, that stock of knowledge, without which you never can rise, but must
make a very insignificant figure in the world. Consider your own
situation; you have not the advantage of rank or fortune to bear you up;
I shall, very probably, be out of the world before you can properly be
said to be in it. What then will you have to rely on but your own merit?
That alone must raise you, and that alone will raise you, if you have but
enough of it. I have often heard and read of oppressed and unrewarded
merit, but I have oftener (I might say always) seen great merit make its
way, and meet with its reward, to a certain degree at least, in spite of
all difficulties. By merit, I mean the moral virtues, knowledge, and
manners; as to the moral virtues, I say nothing to you; they speak best
for themselves, nor can I suspect that they want any recommendation with
you; I will therefore only assure you, that without them you will be most
unhappy.

As to knowledge, I have often told you, and I am persuaded you are
thoroughly convinced, how absolutely necessary it is to you, whatever
your destination may be. But as knowledge has a most extensive meaning,
and as the life of man is not long enough to acquire, nor his mind
capable of entertaining and digesting, all parts of knowledge, I will
point out those to which you should particularly apply, and which, by
application, you m
