His concerns in Derbyshire, Lancashire, and Scotland, were so extensive and numerous as to show at once his astonishing power of transacting business, and his all-grasping spirit.

Availing myself, however, of what I then saw, I made a loom, in its general principles nearly as they are now made. But it was not till the year 1787 that I completed my invention, when I took out my last weaving patent, August 1st of that year.
Page 46 - Some little time afterwards a particular circumstance recalling this conversation to my mind, it struck me that, as in plain weaving, according to the conception I then had of the business, there could...
