US SUPREME COURT DECISIONS

Under an indenture in the nature of a lease which includes railway sleeping cars and written contracts for letting them to certain railroad companies, and which provides that if the revenue derived from such contracts shall, by reason of the refusal of any of the railroad companies to permit the cars to be run over their lines of road, fall below the sum agreed in the indenture to be paid quarterly by way of annual rent, the lessee "shall have the right either to declare this contract null and void and surrender" to the lessor the property leased

"or shall and will pay in like manner, in lieu of said sum, such sum or share of the net revenue from the remaining lines of the roads as the parties hereto may at that time agree upon,"
