 person conversant in matters of this kind to imitate 



the invention, even without ever having seen the work 

 executed. The principles at least on which this con- 

 trivance is founded will be perfectly evident ; and, when 

 they are understood, ingenious men will find little dif-

 indeed highly probable that simpler and better means 

 of applying them will be found than those I have 

 adopted, when the use of the contrivance shall become 

 more general. I am indeed aware of several alterations 

 of the machinery which I think would be improve- 

 ments ; but, as I have not tried them, I dare not re*
