"I don't know. She manages to do the most unexpected things," said Jessie.
But there was so much to do in helping settle things and make the sparsely furnished bungalow comfortable that Jessie did not think for a while about Henrietta. Besides, she was desirous of setting up the radio instruments at once and stringing the antenna.
Darry and Burd helped the girls do this last. They worked hard, for they had first of all to plant in the sands some distance from the house an old mast that Mr. Norwood bought so as to erect the wires at least thirty feet above the ground.
The antenna were not completed at nightfall. Then, of a sudden, everybody began to wonder about Henrietta. Where was she? It was remembered that she had not been seen during most of the afternoon.
"Oh, dear!" worried Jessie. "It is my fault. I should not have let her go out alone that time, Amy."
"She said she wanted to see her island, I remember," admitted her chum, with some gravity. "And this island is a pretty big place, and it is growing dark."
"She could not get into any trouble if she stayed on Hackle Island," declared Darry. "What a kid!"
"And she certainly couldn't have got off it," suggested Burd.
"We must look around for her," said Jessie, with conviction. "Don't tell Momsy. She will worry. She thinks I have had my eye on the child all the time."
"You certainly would have what they call a roving eye if you managed to keep it on Henrietta," giggled Burd Alling. "She darts about like a swallow."
