Certain things are good for nothing until they have been kept a long while; and some are good for nothing until they have been long kept and used.

Context

“I liked the turn the conversation had taken, for I had some things I wanted to say, and so, after waiting a minute, I began again.—I don’t think the poems I read you sometimes can be fairly appreciated, given to you as they are in the green state. —You don’t know what I mean by the green state? Well, then, I will tell you. Certain things are good for nothing until they have been kept a long while; and some are good for nothing until they have been long kept and used. Of the first, wine is the illustrious and immortal example. Of those which must be kept and used I will name three,—meerschaum pipes, violins, and poems. The meerschaum is but a poor affair until it has burned a thousand offerings to the cloud-compelling deities.” source
