David Josiah Brewer,
Talbott v. Board of County Commissioners of Silver Bow County…
“ Power to tax is power to destroy. Given to the state the power to tax any of the instrumentalities which the United States creates for the exercise of its jurisdiction, and the former may impede, if not wholly stop, the latter in the discharge of its duties as sovereign. Hence, by necessary implication, the absolute exemption from state taxation of any of the instrumentalities, and among them are national banks, which the United States creates for the exercise of its powers and the discharge if its duties. But the whole argument fails when applied to a territory. ”
