The dreaded White Caps, have made their appearance in our town.  Sam Young, colored, received a notice last night, embellished with skull and crossbones, to leave the town within forty-eight hours, or be dealt with according to White Cap law.  He was arrested this morning charged with stealing a pair of gloves.  He gave bond for his appearance at next regular term of court.  He is strongly suspected of several other larger thefts.

Whitewright, Tex., March 24. - Robert Osborne, a railroad man, received the following notice yesterday from unknown parties styling themselves whitecaps. The note read as follows:

Robt. OSBORNE: You are informed to leave this town inside of twenty-four hours. The best thing you can do is to leave this town.
WHITE CAPS

Mr. Osborne is a young man and has always enjoyed the reputation of being a law-abiding citizen. He stated to THE NEWS reporter that he was here to stay and if the whitecaps wanted him he was at their service. The notice was mailed in the post office here. OSBORNE seems to take the matter in a cool manner and says he is ready for the whitecaps at any moment they see fit to attack him.
