“Oh, no, no, no!”

“Don’t blame you,” put in Brad. “If Maro wears that thundercloud on his mug all the time, he’d frighten a Hottentot, much more a civilized girl. Go change your face, Maro.”

The young man did not seem to understand this fully, but he darted a deadly look at Brad, then urged his companion to make a move at once.

“Look out, boys—look out!” panted Professor Gunn. “He says you are mere children and easily crushed. He wants to attack you at once.”

“Whoop!” cried Brad, squaring away. “Let him wade right in! Let them both break loose and come at us! They’ll find the children ready for business, you bet your boots!”

“Steady, Brad,” cautioned Dick. “We’ll fight if we have to.”

“And I sure reckon we’ll have to, pard.”

“It looks that way, but let’s not rush matters. Keep a cool head.”

Dick feared the men were armed, which would give them an additional advantage. Under ordinary circumstances it would not seem a difficult thing for them to obtain the mastery over the two boys, but those boys, in spite of their years, were remarkable athletes and clever fighters, and they believed they could hold the Greeks good play unless deadly weapons were produced. Neither lad counted on assistance from Professor Gunn.

The elder man grew impatient and again demanded possession of the girl, asserting that the boys would be punished for interfering, as he was the one who had sole authority over her.
