Notice to Correspondents . 
away from the necessity of European importation. Those who think 
we ought to depend on Great Britain, for all our necessary comforts 
and luxuries, and raise nothing, and export nothing, but raw mate- 
rials for British traders to work up and sell to us in a new form, 
will doubtless be the advocate’s of foreign commerce, and of all its 
concomitants : they will not approve of such a work as this, or 
wish success to any home manufacture, which will so far supercede 
the necessity of foreign importation. If readers of this description 
disapprove of the principles advanced in this work, I cannot help 
it : but most assuredly, a work that professes to aid the exertions 
of home trade, may without impropriety be permitted to suggest 5 
that the benefits of foreign trade have been overrated ; and allowed 
to state the facts and arguments that support such an opinion. 
But the questions of political economy are really of so much na- 
tional importance — they require and imply so much important fact 
to elucidate them — ‘they are here so new- — and every where so 
unsettled, that I feel ashamed of this apology. I shall be glad to 
receive condensed and well-considered replies to my own opinions., 
I have been collecting, some statistical and financial facts relativfc 
to Great Britain, France and this country, which I shall give in 
the next number. 
I have read the first volume of Mr. James Cutbustis manual of 
chemistry, but I have not yet seen the second. There are some 
slight inaccuracies in the first, but it is a useful compendium r 
containing as much fact in as small a compass, with as little unne- 
cessary matter, as any compilation I have seen for some time. I 
shall be glad of an opportunity of expressing myself as favourably 
of the second volume ; which I dare say I shall be enabled to do 
very truly. 
I have read the first part of a treatise on distilling, by Mr. Har* 
iris on Hall , of Philadelphia. If a few pages of chemical disqui- 
sition were omitted, and some practical directions given on the use 
©f the hydrometer, it would be the best book I have seen on the 
subject. Indeed I consider it such as it is. It supercedes a great 
deal of what I had to say on this manufacture, but I can make 
Some additions when the proper time comes. 
I have received the description of Dr. Allison’s machine for 
spinning wool, which shall have a place in the next number of the;
