Languid Plate? Inactive, inert, sluggish, torpid, spiritless, weak, feeble, weary, exhausted, or debilitated? Please explain the usage as per a steam whistle and how it got its name. Is this the flat surface that forms the top of the cup? And if it is, I blew it over-top the smoke stack of the DELTA QUEEN when the whistle was taken down and at the gold-plating shop. It landed on the roof aft of the smokestack, and it must have been blown a mile high, maybe more, because it took forever to land. Had that piece of the whistle, we are discussing, gone down the stack and into the inferno below, my steamboatin' days would have ended that day, and quite possibly that famouse whistle might have been replaced with another, but fate smiled on me and no one ever knew, so, everyone, please.... keep this to yourselves.
