As by the dead we love to sit — Deadhead

As by the dead we love to sit, 1
Become so wondrous dear-
As for the lost we grapple
Tho' all the rest are here-

In broken mathematics 5
We estimate our prize
Vast-in its fading ration
To our penurious eyes!

DEADHEAD.-Freely translated, this means a person who lives on community; but as applied to the press, signifies those who pay nothing for their amusements, and who ride over railroads free. ─ Young America, Volume I (1856)

This conspiracy happened to be defeated by the single fact (succeeded by a little management) that the sheriff sought to pass me at the door of the theatre as "a deadhead." ─ The Life of P. T. Barnum (1855)
