CUTTING A LAMP-GLOBE.
Thither Lawrence went, and saw the difference; yet
the engraving, too, was only a species of grinding. The engraver sat on a
high stool before a swiftly whirling little copper wheel, not more than two
inches in diameter. To the edge of this he touched occasionally a mixture
of oil and emery, in a little shallow dish, then pressed firmly upon it the
article he was engraving.
