     "O Lord!" says Mr. Smallweed, panting. "Oh, dear me! Oh, my stars! My dear friend, your workman is very strong—and very prompt. O Lord, he is very prompt! Judy, draw me back a little. I'm being scorched in the legs," which indeed is testified to the noses of all present by the smell of his worsted stockings.
