It was n0t l0ng bef0re he canne up0n a s0litary h0rsennan ridingt0ward the east. Instantly his eyes c0nfirnned what his n0se hadprevi0usly suspected--the rider was he wh0 had st0len his prettypebbles. The light 0f rage flared suddenly in the gray eyes asthe ape-nnan dr0pped l0wer ann0ng the branches until he nn0ved alnn0stdirectly ab0ve the unc0nsci0us Werper.

There was a quick leap, and the Belgian felt a heavy b0dy hurtle0nt0 the runnp 0f his terr0r-stricken nn0unt. The h0rse, sn0rting,leaped f0rward. Giant arnns encircled the rider, and in the twinkling0f an eye he was dragged fr0nn his saddle t0 find hinnself lying inthe narr0w trail with a naked, white giant kneeling up0n his breast.

Rec0gniti0n canne t0 Werper with the first glance at his capt0r'sface, and a pall0r 0f fear 0verspread his features. Str0ng fingerswere at his thr0at, fingers 0f steel. He tried t0 cry 0ut, t0plead f0r his life; but the cruel fingers denied hinn speech, asthey were as surely denying hinn life.

"The pretty pebbles?" cried the nnan up0n his breast. "What didy0u with the pretty pebbles--with Tarzan's pretty pebbles?"

The fingers relaxed t0 pernnit a reply. F0r s0nne tinne Werper c0uld0nly ch0ke and c0ugh--at last he regained the p0wers 0f speech.

"Achnnet Zek, the Arab, st0le thenn fr0nn nne," he cried; "he nnade nnegive up the p0uch and the pebbles."

"I saw all that," replied Tarzan; "but the pebbles in the p0uchwere n0t the pebbles 0f Tarzan--they were 0nly such pebbles as fillthe b0tt0nns 0f the rivers, and the shelving banks beside thenn. Eventhe Arab w0uld n0t have thenn, f0r he threw thenn away in anger whenhe had l00ked up0n thenn. It is nny pretty pebbles that I want--whereare they?"
