through the northwest corner of the Philip Duty survey, and continues in the same direction to the centre of the Martha Ingram headright; northerly through the Ingram and James Ritchey headrights, and then has a northwesterly course through the Richard M. Allen and Cass County school lands, across Black Bayou, and through the southeast corner of the P. M Keeton headright. The course is then east to the west side of the Jane Ritchey headright, slightly south of east through the Albert Pride headright, and thence northeasterly to the southwest corner of the W. W. Holman survey; thence irregularly to the Arkansas State line, near the northeast corner of the Cass County school land. The line then turns north of west to near Alamo Station, on the Texas and Pacific Railway, southerly along the Texas and Pacific Railway to the northwest corner of the John C. Cooksey headright, westerly to the center of the John Myers headright, and from there in a general west of south direction to the southeast corner of the north Berry Wilkins tract. The line then turns southeast to near the centre of the south side of the Luke Roberts survey; east to the west side of the P. M. Keeton headright. From this point the course of the line is a general west of south direction to the southwest corner of the John Nall headright; then west to the southwest of the Thomas Wilson; north, to north side of the H. J. Storey headright; southwest to the southeast corner of the Jarius Barry headright. From here it turns northwesterly to the northeast corner of the Luanna Ward survey, then west to the southwest corner of the Henry Buckler headright. From this point it turns in a northwesterly direction and passes into the P. H. Tuckett survey in Morris County.

The area embraced within these boundaries has an extent of about foul hundred and fifty square miles.

Although this area comprises the chief ore producing region of Cass County it also embraces many miles of territory within which no ore occurs. The oreless regions are chiefly among the bottom lands of the larger creeks and second bottoms in the northeastern portion of the county. Of the bottom lands along the creeks the best example is those of Black Cypress, which, upon the line of road between the town of Linden and the Avinger station, on the East Line Railway, are in the neighborhood of three miles wide. Many of the ridges in the same are also entirely formed of sand, and either contain no ore, or the ore lies too deep for any practical purpose.

The actual area of ore bearing lands within the county will not fall much short of three hundred and fifty square miles, which may be apportioned among the several divisions as
