NOTICES. 
I HAVE received from Mr, Thomas W. Ruble* of Ken- 
tucky, notice of a steam engine of his invention, where the water 
of the boiler surrounds the cylinder. I suspect that although this 
arrangement has its conveniences, it is not new. I have heard of 
it in use in England. 
Want of a plate prevents me from inserting Professor Cut- 
bush's paper on Mr. Cloud’s method of making seltzer water. It 
will appear in the next Emporium. 
My publishers write to me, that complaints are made of my 
papers on manufactures being too long. They ask when I begin 
the subject of dying. 
My design in this work is to make it the best publication 
any where extant, as a body of information on MANUFAC- 
TURES. I do not profess, I will not condescend to skim 
over my subjects with the appearance of knowledge, but with 
useless or shallow information, where good can be obtained, 
I dedicate at least one third of this vrork, greatly against my own 
inclination, to miscellaneous and comparatively trilling papers. 
About these I care little. But I say to those who complain, 
Shew me in any European language, the same amount of real 
information* on iron, Steely Steam Engines , Cofifier , and Lead in 
the same brief compass as I have given it. 
Shew me, any single European publication on either of these 
subjects, that contains any thing approaching to the same quantity 
of important knowledge, which the Emporium has furnished 
I say to those who complain, that they cannot shew this. I 
know it. 
Under these circumstances, if the work be such as I represent 
it (and if it be not, let those who can shew otherwise)— if it really 
do contain a condensed body of manufacturing information, not to be 
found but by hunting up publications scarce, voluminous, and dear* 
and not then — what reason have I to change my plan, or to suspect 
that such a work will not be reasonably supported ? If it be not, it 
is well : I will give it up : but I will not swerve from my own 
ideas of propriety in conducting it. 
As to dyeing, I suppose there may be twenty or thirty subscri- 
bers anxious for such an article, and caring nothing about any other 
part of the work : I believe the articles I have published, of far 
more importance ; but it shall have its turn* T. C.
