To this short time allowed for labour I desire may be added the exceeding laboriousness of my work; the many hours which, for want of tools, want of help, and want of skill, everything I did took up out of my time. For example, I was full two and forty days in making a board for a long shelf, which I wanted in my cave; whereas, two sawyers, with their tools and a saw-pit, would have cut six of them out of the same tree in half a day.
