Continued. 
1 PROCEED now to give an account of the improve- 
ments, or supposed improvements, that have been sug- 
gested subsequent to the patent of Mr. Watt, of Bir- 
mingham, 
In so doing, I shall confine myself to the statement of 
facts. Whatever my own opinion may be, I feel the ab- 
sence of twenty years practical knowledge, too strongly, 
to conceive my opinions entitled to any weight : if it 
were otherwise, the fairest and most satisfactor}^ course for 
me to pursue, is to give information from which others 
may make up their minds on any preference which dif- 
ferent plans may be entitled, I shall present, as faithful- 
ly as I can, all the useful knowledge on this subject, that 
the compass of this publication will enable me to furnish. 
My own actual experience, extends no farther than an 
eight hour engine of Watt’s construction, which for 
about two years was under my own management. What- 
ever else I may know, I derive from the same sources 
I present to n^ reader.
