A Letter to a friend of the Editor , on Manufactures. 
Sir — A s I believe to promote the internal improvement, do= 
me Stic trade, and industry of this country, is amongst the greatest 
services that can be rendered its society, you will not be surprised

fire, air, earth and water, gives to each of them the power of pro- 
ducing sufficient to exchange for the labour of many agriculture 
alists, or persons employed in occupations that can only be per- 
formed by mere human labour. Let us endeavour to explain this 
imperfect subject and form some computation of what she gains in 
money, and then estimate from this, the number of human beings it 
would require to produce by their labour such an amount. 
It is proper to premise, that the sums are stated on conjecture ; 
but the principle is correct ; and this paper is only intended to set 
you at work. The true data can be found in public documents, 
and British works on political economy, while much assistance 
may be had from Cooper, Fulton, T. Cox, Bolman, &c. 
In the last published number of the Emporium, I think Cooper 
states the saving to the British from using Watt and Bolton’s
