dead wagon
n.— «The “dead wagon” was put on the Harlem company’s trade. This wagon is run by the protective association nominally to collect milk cans, witnesses testified, but its real value lies in the canvassing of every customer of a dealer marked for destructions. His price is cut and milk is offered even below cost price to win away his customers.» —“Milk Trust Gets Airing” in New York City Nebraska State Journal (Lincoln) Dec. 26, 1909.
