Context: Here was the world's worst wound. And here with pride
'Their name liveth for evermore' the Gateway claims.
Was ever an immolation so belied
As these intolerably nameless names?
Well might the Dead who struggled in the slime
Rise and deride this sepulchre of crime.

Variant: If a man has to say trust me, Gogu conveyed, it's a sure sign you cannot. Trust him, that is. Trust is a thing you know without words.

In an obituary, Canada Law Journal, January 1, 1881, p. 11. According to the journal: "[Cockburn] subsequently acquired a large practice in London in railway and election cases. Although he did his best for his clients, he was careful that they should do their duty by him, and the story is told that on one occasion, when an election committee met, Mr. Cockburn, the counsel for one of the parties, was absent because his fee had not accompanied the brief and the only message left was that he had gone to the Derby, with the remark that 'A man might as well play for nothing as work for nothing'".
