132 On the Rise and Progress 
of power-looms have lately been brought for- 
ward, and some of them appear to have impor- 
tant advantages over any other construction 
that has hitherto been in use. Their real va-~ 
lue however can be determined only by time 
and experience. 
It should: be recollected that ania 
of ingenious contrivances have been tried 
and laid aside, before spinning machines 
were brought to their present state of perfec- 
tion. To give more particular descriptions 
of them, or of the operations performed by 
them, would extend this paper beyond its 
proper limits. I may observe however that 
their united effects amount to this, that the 
labor of one person, aided by them, can now 
produce as much yarn, in a given time, as. 
200 could have produced 50 years ago. 
. By these means, cotton fabrics have been 
produced, of such variety and usefulness, as 
to be sought after by the people of every cli- 
mate, and of every stage of civilization. 
I have not been able to obtain any informa- 
tion respecting the circumstances that first 
led to the establishment of the cotton’ manu- 
factory in this part of thewisland: After it 
was once commenced, however, its extension 
in this quarter appears to have been promoted
