Turnbuckles are also used extensively in watercraft and aircraft to regulate the lengths and tensions of riggings and rope and cable lines. In all applications, turnbuckles should be selected to be at least as strong as the cable or rope to which they're secured.
The Wade-Davis Bill of 1864 was created by the Radical Republicans, who believed that absolute punishment had to be levied against the South as a condition of re-admittance during Reconstruction. The bill called for a complete abolition of slavery to prevent it from surviving in any way after the war.
The Wade-Davis bill passed easily in congress on July 2nd of 1864. However, the bill never went into effect. It was pocket vetoed by Abraham Lincoln. The bill was passed only four days before congress was adjourned for break in 1864. Later, reconstruction would take a similar root to that proposed by Wade and Davis.
