from The Century Dictionary and Cyclopedia
- n. Same as sheers, 2.
Sorry, no etymologies found.
The later item seems impossible to find in a treeless place of low hills and snow until a miner named Lawson comes up with the idea of making a tripod of oars, lashings and guyropes — a "shears" (or shear-legs) in sailor lingo — to swing Jan off to his reward.
By exercising much ingenuity in devising shear-legs, he at last succeeded in lifting the masts into their allotted receptacles, where they were firmly secured.
