Mr. [Augustine] Birrell has, as usual, quoted very liberally, and to excellent effect. Quotation is an art the difficulty of which may easily be underrated by paragraph-writers or by persons who do not write at all. You may say no end of wise things about a writer, and yet fail to convey a sense of the peculiar flavor for which you really value him. To insinuate a phrase or verse of our author into the midst of our own readable (because ephemeral) discourse, is all most of us may do, without giving our readers an unpalatable suspicion that they are being seduced into the perusal of a real author. Mr. Birrell quotes by the page, and we gratefully read every line because we are sure Mr. Birrell, at least, is incapable of asking us to read anything inconsequent or dull.

A price that has been quoted for buying or selling.

Let's get a quotation for repairing the roof before we decide whether it's worth doing.

The act of setting a price.
