Tavia and the boys were not informed of the new mystery regarding the water-rights affair. Dorothy had promised Aunt Winnie not to speak of it at present.

“After working as hard as we do all day,” quoth Ned at the supper table that night, “a fellow needs a little recreation in the evening. You girls aren’t at all entertaining. Why! you haven’t had even a ‘sing’ since we came out here to the ranch.”

“I’ll ask Flores,” promised Dorothy, briskly. “Just as soon as supper is over.”

“And we’ll all sing,” announced Ned, gravely.

Tavia immediately relinquished her knife and fork. “I object,” she declared. “Perhaps I should say that I rise to a point of order.”

“What about, Miss?” demanded Ned.

“Are you going to attempt to sing?” asked Tavia, point blank.
