Joseph McKenna, Armour Company v. North Dakota…
“ The advantages are in a sense made a snare, and the testimony means no more than that the packer has built up a trade on a system of gross weight which enables it to practice a kind of deception on the purchaser that he is getting 3 pounds of lard when he is only getting 2 pounds, 6 ounces, and enables the packer to pay for the container. The evil of the transaction is not in the latter, but in the former,-that is, in the deception. ”
