ribution.—Large outcrops of Grand Gulf sandstone are tobe seen at Harrisonburg and Sicily island. On the dividebetween the Ouachita and Little river the Grand Gulf extendswell to the north, reaching a point near Rosefield, Along theedge of the formation chalk or fine white clay has beenreported in a number of places. From Rosefield, according toHopkins, the northern line of the Grand Gulf follows the BayouFunne Louis to Centerville, then turns west and crosses Littleriver a little below Gilmores ferry. On the Colfax-Winnfieldroad the high Grand Gulf hills are encountered just south ofSaddle bayou. About two miles northwest of CoLfax there is avery good outcrop of Grand Gulf sandstone in Rocky ford.The sandstone is quite abundant as far north as Sec. 19, 7 N.,3 W. Around Lena are large quarries in the Grand Gulf rocks.Hilgard reports these beds as capping the elevated ridgesabout Cloutierville on Red river.* The next notable exposure *Am. Jour.

II) General Geology : Grand Gulf Oligocene 97 of Grand Gulf is in the Kisatchie hills. The road from Lees-ville to Provencal passes through a strip of black prairie landabout four miles from lyeesville called Anacaco prairie. Cal-careous concretions are scattered over the ground in largenumbers but no fossils were seen. Another small calcareousprairie of about four acres in extent occurs north of Hardshell.In about Sec. 5, 4 N., 8 W., a light colored ledge crops out in theroad. Between Kisatchie bayou and Bellewood, sandstonebecomes quite common, and calcareous prairies are still to befound. The northern limit of the sandstone is about Bellewood.On the divide between the headwaters of Kisatchie and Torebayous the Grand Gulf probably extends well to the north, andit may be that the Bad Hill* mentioned by Hopkins as sevenmiles south of Many is in this region. If Bad Hill is seven milesdue south of Many it is Lower Claiborne, for numerous fossils arefound in this region and the distance
