tten. It includes a general knowledge of nearly
everything you can think of; and will be as useful to Bessy and
Hannah as to you.

Chambers' Mathematics, contain all that you are likely to require
in that branch, with the exception of Euclid and Algebra, both of
which you must get, unless you have them. You will need some one to
assist you and explain points in the mathematics and algebra,
otherwise your progress will be very slow. But remember that
whenever you have puzzled over a problem for some time, and cannot
understand it, do not give it up altogether, but leave it for a few
days or weeks and then try it again. It will then, very likely,
appear quite simple, and you will be astonished that you did not
make it out before. You will find the Nautical Almanac very useful,
not only in giving you an idea of astronomical problems, but also
for ascertaining the particulars of any strange stars you may see,
or where to look for the different planets, etc. With the help of
the twelve maps you will soon be acquainted with all the principal
fixed stars.

You should carefully study the Art of Reasoning, as it is what most
people are very deficient in, and I know few things more
disagreeable than to argue, or even converse with a man who has no
idea of inductive and deductive philosophy. After getting the books
I have mentioned, you may spend the balance in any others you
please, but remember, they must be scientific ones. If you write to
Walton and Maberley, 27 Ivy Lane, Paternoster Row, they will send
you a catalogue of books published by them, in which you will find
descriptions of nearly all that I have mentioned and plenty of
others. You can order those you want direct from them, or get them
through a local stationer. I expect you to acquire some practice at
printing, and ornamental writing, in the Bank. If you have a steady
hand, you should exercise yourself at it as much as possible, and
learn mechanical drawing at the same time. Draftsmen get well paid
out here, and are greatly in demand. Being able to print neatly and
evenly is the main point: all the rest is easily learned. My hand
is very unsteady, as you may see by my writing; I do not think I
shall ever be able to write a decent hand. One other piece of
advice I must give you before I shut up; that is, never try to show
off your knowledge, especially in scientific matters. It is a sin
that certain persons we know have been guilty of. The first step is
to learn
