"Oh, nonsense," Hawtry said.

"Look here." And he put his hand into his pocket and pulled out some silver.

Then he made signs of mounting one of the mules, and waved his hand over the surrounding country to signify that he wanted a general ride.
The Spaniard nodded, held up five fingers, and touched one of the mules, and did the same with the other.
"He wants five shillings a head," Hawtry said.
"I don't know," Jack said doubtfully.
