"I've a good mind to throw you into that hole," threatened Merritt.

"Try it," shouted the stout youth, hopping about aggravatingly.

"I will."

Merritt made a rush at the irritating Tubby, who leaped provokingly away. But suddenly he gave utterance to a yell of dismay, as in his efforts to retreat he stumbled into the hole which Jose had dug. By this time, to Rob's astonishment, for he had been watching Jose's methods with interest, quite a lot of muddy water had appeared, and into this accumulation of moisture the stout youth fell with a resounding splash.

Even the solemn Jose smiled as Tubby sputtered and splashed about in the pool.

"Come out of that water," commanded Merritt.

"Call this water?" demanded Tubby, sputtering some of it out of his mouth. "Ugh! it tastes more like soap suds to me."

"Him alkali," grinned Jose, as Tubby scrambled out and stood, rather crestfallen, on the verge of the magic pool; "mucho malo."

"What's 'mucho malo'?" demanded Tubby of Merritt, the self-appointed interpreter.

"It means you're a nuisance," retorted Merritt, which reply almost brought on a renewal of hostilities. Rob checked them, however, by reminding the stout youth that the water was for drinking and not for bathing purposes. The boys were anxious to dip their buckets in and return to the wagon, but Jose told them they must wait till the water cleared.
