These wanderers, and those who are still seen occasionally in the back streets of the metropolis, are said to 'go a-pitching ;' the spot they select for their performance is their 'pitch,' and any interruption of their feats, such as an accident, or the interference of a policeman, is said to 'queer the pitch,'--in other words, to spoil it. [Thomas Frost, "Circus Life and Circus Celebrities," London, 1875]
