About 1834the intendent appears to have become Woodstock the tracks were raised, streetscarried beneath them and grade crossingseliminated. East of Urbana two import-ant road crossings were eliminated, tliestreets being built under the tracks.Complete drainage systems and sewerswere built through the cuts where thegrade was lowered. Incident to the double tracking was thebuilding of entire new freight and pas-senger stations and yards at Covington.Active work on the double tracking fromLrbana to St. Paris is still under way.The grade on Blue Hill, west of the MadRiver, formerly a heavy pull, has beenreduced from i.i to 0.7 per cent, andtlie total lift cut down fifty feet. A littlemore than one-third of the grading isnow complete, and nearly three-quartersof the masonry. From St. Paris to Jor-dans, beside the second track work, aneastbound freight running* track has beenlaid. This finishes the double tracking, except through Piqua, where the tracksarc on a street.. .

An interesting feature ofthe line is the rifled construction of thepipe. The rifling consists of indenta-tions made in the interior of the pipe, .nd following each other in a spiralline. A series of experiments in theconveyance of oil demonstrated thefact that after a small percentage ofwater had been added to the oil, andthe necessary pressure applied, thatthe whole will develop a whirling mo-tion, due to the spiral incline or screwthread form of the ser
