It is a rich storehouse for those who love quotations. It is as full of fine bon mots as a Christmas pudding is full of plums.

Halleck’s image praises a particular book (or body of writing) as a trove for readers who delight in memorable sayings. By likening it to a “storehouse,” he emphasizes abundance and easy retrieval: the text yields quotable lines in quantity. The second simile—“as a Christmas pudding is full of plums”—adds a festive, sensory note: the wit (“bon mots”) is not merely plentiful but pleasantly embedded throughout, so that almost every “bite” contains something sweet and worth savoring. The remark also implies a social function of quotations in cultivated conversation, where ready-made turns of phrase are valued as intellectual treats.
