Note 10 — Introduction.
Reading edition
James I., by Proclamation, in 1615, forbade the manufacture of glass if wood were used as fuel, on the ground that the country was thereby denuded of timber. In 1635 Sir Robert Maunsell perfected a method of manufacturing “all sorts of glass with sea coale or pitt coale,” and Charles I. forbade the importation of foreign glass in order to encourage and assist this new industry.
