These ducts are usually 4^ inches square, random lengths, and 

 have a 3 inch hole bored through. Large conduits with three and four 

 openings are also made and used for underground municipal distribution. 

 Loblolly pine and shortleaf pine were the woods reported for making 

 conduits. These woods being soft and porous are especially desirable 

 for their easy impregnation with creosote. 



Wood blocks for paving city streets are gaining in favor. In 

 1910 the Census figures show that 770 miles of street in this country 

 were wood paved. This is an increase in two years of more than 15 

 per cent. Prevention of decay by creosoting has also been the chief 

 factor in stimulating the demand for wood pavement. Longleaf yellow 

 pine shipped in from Georgia, Florida, and Alabama was the prin- 

 cipal species reported, and until lately has been considered the most 

 practical wood for successfully meeting this use. Water or black 

 gum (Nyssa bifora) is the other paving wood mentioned. The table 

 shows that over a million feet was used last year. Being a cheap hard- 

 wood of compact structure with adaptability for absorbing preserva- 

 tives, water gum blocks are destined to grow in popularity. Creo- 

 soted railroad ties made from this wood were used in the new tunnel 

 recently built by the Pennsylvania Railroad Company under the Hud- 

 son River in preference to ties made from other more expensive woods. 



The manufacture of creosoted paving blocks and conduits is a 

 most important industry in Virginia. In quantity of wood consumed 

 it stood third in the list of the industries and its products were widely 

 distributed over many States. The conduits for the underground line 

 from Boston to New York to Washington, D. C., mentioned above, 

 were made by Virginia factories.
