Greater wearing surface, therefore longer life of rope and less wear upon pulleys. 2. Greater strength, thereby admitting of smaller ropes being used for existing loads, or of increased loads without increase in size of rope. 3. Spliced easily and more effectively. 4. Less tendency to twist and stretch in working. Fig. 18a for Sinking and Fig. lib for Cranes, &c., are non-twisting. Pig. 1 ib.
