[ Broughton / Cometh Up as a Flower ]
The first of two metaphorical-only Newfoundland references occurs in Chapter 15:
"I must go home, else I shall be locked out."
"There would be the devil to pay, then," says Dick, standing up, too, and stretching like a big Newfoundland.
The second and final reference is in Chapter 18:
Dick is stretching his long length, like a big Newfoundland, one step below me; he is looking at the chestnuts, and smiling and saying: -- "Won't we put them along at a tidy pace, Nell? We'll take the shine out of them?"
