"I never knew anything about radio compass stations before," announced Dick.

"That is because you never sailed the seas and had to call on one for aid," smiled Bob. "If you did you would be very thankful, I guess, that the government has so carefully provided some one to answer just the sort of question you wished answered. I try to remember this when I get hot under the collar because the license for our station does not arrive. Uncle Sam can't help it if his men are slow. The plan at the top is all right. There must be rules to govern wireless stations, be they governmental, commercial, or private; rules to regulate the wave lengths each may use; rules to make sure the operators who have charge of them know their job; and inspectors to make sure that every such rule is obeyed."

"Who has the big chore of following up all these people and making certain that they are conforming to the law?" questioned Mr. Crowninshield.

"The Department of Commerce issues the licenses for all private and commercial stations and sends its inspectors to keep an eye on whatever comes under their control. It is this department that will have jurisdiction over Surfside if the license is granted. Government radio stations on the other hand, not only the high-power class but the coastal stations and everything that pertains to their relations with commercial stations afloat or ashore, whether in the United States or in foreign lands are entirely under the control of the Director of Naval Communications of the Navy Department."

"I wish you'd tell us something more about compass stations," Dick said. "Were you ever stationed at one?"

"Yes, for a little while I was on an island off the coast," replied Bob. "But I did not like it very well and applied for a transfer."

"It must have been lonely as the dickens on an island; worse, even, than being at Seaver Bay. Why in goodness did they build the station there?"

"Why, you see, a compass station that operates independently as that one did is usually situated on a lightship or an island because that location is best suited to the sort of work it has to do."

"And that is?"

"To give ships their positions when they sing out to ask exactly where they are," replied Bob. "Since the station is fairly well out to sea itself, it is able to furnish excellent cross-bearings and set the vessel on her course in case she is off it. Ships have been known to miss their way, you know, especially in a fog; and if they have not missed it they are often very grateful to be assured they have not and that their own calculations were correct. So the rule is that an operator must always be listening in for at least three minutes at ten, twenty-five, forty, and fifty-five minutes past the hour and be ready to answer a Q T E when he hears it."
