Handbook of clearing and grubbing methods and cost

The Handbook of clearing and grubbing methods and cost : Gillette, Halbert Powers, 1869- from 1917 is but one in a whole slew of engineering and costing books by Mr Gillette. I was brought to this book by reading about the Erie Canal, where the dense forests of the middle section of the Erie Canal, between Seneca and Rome, surveyed by Benjamin Wright, included the grubbing of the heavy forests as part of his $1,500 per mile estimate; cf. Hulbert, Erie Canal, p.109.
