In Brown v. Houston, 114 U.S. 622 (1885), it was decided that coal, mined in Pennsylvania and brought in boats by river from Pittsburg to New Orleans, to be there sold by the boat-load on account of the Pennsylvania owner, and remaining afloat in its original condition and original packages, was subject, in common with all other property in the city, to taxation under the general tax laws of Louisiana; and the court referred to Woodruff v. Parham (1868), 8 Wall. 123, 139, as upholding the validity of a "tax laid on auction sales of all property indiscriminately," and "which had no relation to the movement of goods from one State to another." 114 U.S. 634.
