13226. TAPES, Surveyors' Chain, graduated on Babbitt Metal. This tape will answer the require- 

 ments of the most severe usage and take the place of the old-time steel chain. It is made 

 of practically unbreakable steel, heavily coated with white metal to prevent rusting and cor- 

 rosion, and somewhat heavier than the ordinary chain tape. The graduations are stamped into 

 Babbitt Metal at each foot (end feet in tenths), or at each link (end links in tenths), so that 

 the graduations can readily be felt as the tape is allowed to pass through the hand. Each 

 tape is provided with a pair of detachable handles, and the reel, which is built especially for 

 such tapes, has a nickel-plated frame with folding winding handles, is easily wound and of 

 beautiful finish.
