Stephen Johnson Field,
Fort Leavenworth Company v. Lowe…
“ But not only by direct purchase have the United States been able to acquire lands they needed without the consent of the states, but it has been held that they possess the right of eminent domain within the states, using those terms, not as expressing the ultimate dominion, or title to property, but as indicating the right to take private property for public uses when needed to execute the powers conferred by the constitution ”
