Charles Evans Hughes, Virginia v. West Virginia (238 U.S. 202…
“ After stating that an 'equitable proportion' of the public debt shall be assumed by West Virginia, it is provided that 'the legislature shall ascertain the same as soon as may be practicable, and provide for the liquidation thereof, by a sinking fund sufficient to pay the accruing interest, and redeem the principal within thirty-four years.' If there could otherwise by any doubt as to what was embraced in the contract of assumption, this provision would dissipate it. ”
