"I know you will. You were ever good to your brother." She patted the big fellow's hand. "And mind the pair of you come to see me when you can. You'll be busy, I know; but you mustn't forget your mother."

"We'll not do that," cried the boys in chorus.

Nevertheless in spite of the promise there were few opportunities during the next few days for either of them to go a-visiting. The New York electricians arrived and with them came aerials, generators, detectors, tuners, insulators, amplifiers, and all the hundred and one parts necessary for a perfectly equipped radio station. Mr. Crowninshield had indulged in no cheap outfit. On the contrary he had purchased the best there was to be had and as the coils of copper wire, glistening wire rope, and spotless porcelain insulators were unpacked Bob's eyes sparkled with anticipation. With the touch of a connoisseur he handled the materials, examining the quality of each. What was Greek to the others was familiar ground to him.

A low building adjoining the boathouse had been hurriedly constructed and it was here, where the new station was to be situated, that an interested audience congregated daily. Perched on an overturned packing case Mr. Crowninshield surveyed the installment of the novel toy which was not only to gratify Dick's birthday longings but also, he hoped, bring to him the information he coveted concerning Lola.

Much as he knew about stocks and bonds he was as much of a novice in the presence of things electrical as were either his son or Walter King, and therefore to their avalanche of questions he added still others, gratefully accepting the information Bob offered with the eagerness of one who is not too superior to learn.

"What is that thing they are putting in place now?" inquired he. "And what is it for?"

"Oh, even I can answer that, Dad!" cried the delighted Dick. "That is the aerial or antenna and it catches the wireless waves as they travel through the air. The higher and longer it is the better, so far as messages are concerned—that is, within certain limits."

His father's eyes twinkled.

"Where did you pick up so much knowledge?" chuckled he.

"Bob told me."
