They were interrupted by Mrs. Allen: “My dear Catherine,” said she, “do take this pin out of my sleeve; I am afraid it has torn a hole already; I shall be quite sorry if it has, for this is a favourite gown, though it cost but nine shillings a yard.”

“That is exactly what I should have guessed it, madam,” said Mr. Tilney, looking at the muslin.

“Do you understand muslins, sir?”

“Particularly well; I always buy my own cravats, and am allowed to be an excellent judge; and my sister has often trusted me in the choice of a gown. I bought one for her the other day, and it was pronounced to be a prodigious bargain by every lady who saw it. I gave but five shillings a yard for it, and a true Indian muslin.”

Mrs. Allen was quite struck by his genius. “Men commonly take so little notice of those things,” said she; “I can never get Mr. Allen to know one of my gowns from another. You must be a great comfort to your sister, sir.”

“I hope I am, madam.”

“And pray, sir, what do you think of Miss Morland’s gown?”

“It is very pretty, madam,” said he, gravely examining it; “but I do not think it will wash well; I am afraid it will fray.”

“How can you,” said Catherine, laughing, “be so—” She had almost said “strange.”

“I am quite of your opinion, sir,” replied Mrs. Allen; “and so I told Miss Morland when she bought it.”
