“I understand that,” said Jessie. “But can an amateur build and practically work this new circuit?”
“Why not? If you follow directions carefully. And with the new outfit a loop is just as effective an antenna as an outside aerial. They say, too, that to catch broadcasting for not more than twenty-five miles, not even a loop is needed, the circuits themselves acting as the absorbers of energy.”
“I’m going to try it,” declared Jessie, with more confidence. “But I feel that I understand so little about the various forms of radio, after all.”
“You have nothing on me there,” laughed the operator. “I am learning something new all the time. And sometimes I am astonished to find out how, after five years of work with it, I am really so ignorant.”
The girls had a very interesting visit at the station; and from the operator Jessie and Amy gained some particular instruction about sending and receiving messages in the telegraph code. He received several messages from ships at sea while the girls remained in the station, and likewise relayed other messages received from inland stations both up and down the coast and to vessels far out at sea.
“It is a wonderful thing,” said Nell, as the girls walked homeward. “I never realized before how great an influence wireless already was in commercial life. Why, how did the world ever get along without it before Marconi first thought of it?”
“How did the world ever get along without any other great invention?” demanded Amy. “The sewing machine, for instance. I’ve got to run up a seam in one of my sports skirts, for there is no tailor, they say, nearer than the hotel. I do wish a sewing machine had been included in the furnishings of your bungalow, Jess. I hate to sew by hand.”
The boys had come in before the Roselawn girls returned for dinner, and they were very enthusiastic over a plan for taking a part of the bungalow crowd on an extended sailing trip. They had met Dr. Stanley walking the beaches, and he had expressed a desire to go to sea for a day or two, and at once Darry and Burd had conceived a plan for the young folks to be included.
“The doctor is a good enough chaperon,” said Darry, with a laugh. “Nell shall come. Her Aunt Freda will be down to look after the children.”
“And Henrietta?” asked Jessie, hesitatingly.
