"Si, si, muchas gracias!" cried Nan eagerly, and employing at once all her Spanish vocabulary. She deposited the puppy in her lap and reached out to shake hands. Keith flicked the horse with his whip. He, too, had recollected a word of Spanish, and he used it now.

"Adios!" he shouted.

And Gringo he became henceforth.

"What kind of a dog is he?" she asked.

Keith grinned sardonically.
