"Oh, dear! you said you'd take good care of me," he sighed, as the sun seemed to drop behind the hill all of a sudden.
"Well I am taking good care of you as hard as I can. Don't be cross, child; I'll go in a minute," said Nan, who considered five-year-old Robby a mere infant compared to herself.
So little Rob sat looking anxiously about him, and waiting patiently, for, spite of some misgivings, he felt great confidence in Nan.
"I guess it's going to be night pretty soon," he observed, as if to himself, as a mosquito bit him, and the frogs in a neighboring marsh began to pipe up for the evening concert.
"My goodness me! so it is. Come right away this minute, or they will be gone," cried Nan, looking up from her work, and suddenly perceiving that the sun was down.
"I heard a horn about an hour ago; may be they were blowing for us," said Rob, trudging after his guide as she scrambled up the steep hill.
"Where was it?" asked Nan, stopping short.
"Over that way;" he pointed with a dirty little finger in an entirely wrong direction.
"Let's go that way and meet them;" and Nan wheeled about, and began to trot through the bushes, feeling a trifle anxious, for there were so many cow-paths all about she could not remember which way they came.
On they went over stock and stone again, pausing now and then to listen for the horn, which did not blow any more, for it was only the moo of a cow on her way home.
