Fir staves at Seattle, Wash. (December, 1912), were quoted at $30 

 to $32 per thousand feet b. m., according to size, etc. They take the 

 same freight rate as lumber of the same class. Redwood staves at 

 San Francisco were quoted at about $45 per thousand. The price of 

 malleable iron shoes, at Marion, Ind., was approximately $3.75 per 

 hundredweight on lots of from 1,000 pieces to a carload, with an 

 additional charge of 10 cents per hundredweight if dipped in rust- 

 proof paint. Drop forged steel shoes 3-J inches long were quoted at 

 2f cents to 3| cents each at Ballard, Wash., and 5-inch shoes at 3| 

 cents to 4 cents each. 



Bands made at Pueblo, Colo., were quoted f. o. b. Spokane, Wash., 

 at $2.97 per hundredweight for carload lots, 10 cents per hundred- 

 weight additional being charged if required to be bent and dipped. 



Steel tongues are quoted at the same prices as bands. 



Pipe coating of a well-known brand used as a dip for bands was

MACHINE-BANDED PIPE. 



Machine-banded pipe is being very extensively manufactured on 

 the Pacific coast and .at several points in the Eastern States. The 

 principal factories of the West are at San Francisco, Cal. ; Portland, 

 Oreg. ; Tacoma, Wash. ; Seattle, Wash. ; and Vancouver, B. C. Other 

 factories are at Elmira, N. Y. ; Bay City, Mich. ; Williamsport, Pa. ; 

 and Alexandria, La. 



Redwood is used for the pipe made at San Francisco, while fir is 

 used exclusively at the other western points mentioned. The eastern 

 factories use white pine and tamarack, principally, for water pipe, 

 and hard maple, beech, and birch for special mining purposes. In 

 Louisiana, water pipe is made from cypress, which wood is used also 

 for steam-pipe casing. 



The original machine-banded pipe consisted of logs turned in a 

 lathe, machine bored, and then wound with continuous flat steel 

 bands. Pipe of this type in sizes from 2 to 6 inches in diameter is 

 still manufactured in Michigan, but most of the machine-banded pipe 

 is now made up of staves, the sections ranging in length from 8 feet 

 to 12 feet in the East, and to 20 feet in the West. Diameters run 

 from 2 inches up to 48 inches. Western factories, however, build 

 little pipe of this kind more than 24 inches in diameter.
