from the bobbin over a glass rod through two plates of 

 iron nicely graduated ;to another bobbin ; the machine is 

 tended by a little girl. 



PROCESS 4. SPINNING THE SILK SINGLE. 



This is done by a man on the spinning frame. The 

 spindles in this frame turn 1800 times in a minute, and 

 the wheels are so graduated that any number of twists to

PROCESS 5. TRAMMING OR DOUBLING THE SILK. 



This is done by a girl at an engine constructed after 

 a model, for which a pattern was brought from a patented

 England ; but as their patent laws do not reach here it 

 has been put into use and operates well ; by this ma- 

 chine the silk is doubled any number of times required, 

 so as to make a thread of the size required whether it be 

 coarse or fine. 



PROCESS 6. THROWSTING OR TWISTING THE SILK. 



This is done by a man on the throwsting frame, which 

 is constructed on the model of one imported from En- 

 gland, and is so contrived by means of various small cog 

 wheels, that the silk may be twisted any given number 

 of twists to the inch. The five machines, or engines last 

 named, are driven by water power, and by the assistance 

 of one man, one, boy and four girls, I have caused over 

 three hundred weight of silk to be manufactured the past
