lines. Fivesuch lines of deposits are shown, all but one being determined byat least three points. The westernmost line contains Saratoga, Day-ton, and Damon; the second contains Sour Lake, Barber Hill, KiserHill or Columbia, and Big Hill, Matagorda County; the third con-tains Spindletop, Big Hill, Jefferson County, High Island, and prob-ably Bryan Heights; the fourth contains Sulphur, Vinton, and SabinePass; and the fifth, Spring Hill and Hackberry. Other points inLouisiana do not appear to observe this linear arrangement, althoughfurther investigation of this region may extend the system to includethese as well as the famous Salt Islands. It is of interest to note that these lines are almost exactly parallelto the most prominent structural feature in the entire Texas region,namely, the Balcones fault, which has been described by Hill as pass-ing through the center of the State. Further confirmation of the sig-nificance of these lines is afforded by the work of Veatch in the salines

HAYES ANDKENNEDY D) ACCUMULATION OF OIL. 145 of northern Louisiana.a lie has shown that these saline springs areassociated with dome-shaped uplifts and that they fall naturally intoa linear arrangement, the axes being parallel with those of the GulfCoastal Plain and probably continuations of the same. The lines shown on the map may be considered as coinciding withthe main structural axes of the region, which are actual or potentiallines of dislocation, either by folding or by fracture. The date ofinitial movement on these axes can not be fixed exactly, but it mustbe as far back as the Miocene, since the thickness of Miocene forma-tions is affected by the doming which has taken place at variouspoints. The movement has been continued through the late Tertiaryand into the present, since it affects the most recent deposits of theregion, excepting perhaps the present river alluvium. The initialmovement may even date back to Cretaceous time, and some evidencein the northern Louisiana saline
