Note 131 — Chapter X · Boulton and the Steam Engine—Correspondence with Watt.

“As I found the engine at Kinneil perishing, and as it is from circumstances highly improper that it should continue there longer, and as I have nowhere else to put it, I have this week taken it to pieces and packed up the ironwork, cylinder, and pump, ready to be shipped for London on its way to Birmingham, as the only place where the experiments can be completed with propriety. I suppose the whole will not weigh above four tons. I have left the whole of the woodwork until we see what we are to do.”—Watt to Small, 20th May, 1773. Boulton MSS.
