THE CELEBRATED
_COLD-ROLLED SHAFTING._

This Shafting is in every particular superior to any turned Shafting
ever made. It is the most ECONOMICAL SHAFTING to buy, being so very
much stronger than turned Shafting. Less diameter answers every
purpose, causing a great saving in coupling, pulleys and hangers.
It is perfectly round, and made to Whitworth Gage. All who give it a
trial continue to use it exclusively. We have it in large quantities.
Call and examine it, or send for price list.
