a splice for forming a united rope narrow enough to pass through a block, made by unlaying the ends of two ropes for a considerable distance, overlapping the strands so as to make pairs of one strand from each rope, unlaying one of each pair, twisting the other strand into its place in the united rope, and tucking the yarns of the unlaid strand separately into place.
Compare short splice.
