Chapter XXX

When the lord of the manor is showing the beauties of his house and grounds to you, and points out a very fine row of trees for your particular admiration, make no allusion to the magnificence of the avenue at Wimpole; and if he should afterwards show to you one of his pictures, which he values highly as the work of some celebrated master, remember that, although you may have been told privately, by a good authority, that the picture is not really what your friend supposes it to be, you are not called upon to display your borrowed knowledge as your own, and to make yourself odious by endeavouring to convince him that he has been deceived in the purchase.
