"I see," said the boy thoughtfully.
"It's a good deal the same sort of development that's struck the cattle country," the Westerner said, meditatively. "When I was a youngster, a cattle-puncher was really the wild and woolly broncho-buster that you read about in books. In the days of the old Jones and Plummer trail, when there wasn't a foot of barbed wire west of the Mississippi, a cowboy's life was adventurous enough. A round-up gang might meet a bunch of hostile Indians 'most any time, and a man had to ride hard and shoot straight. But now the ranges are all divided up and fenced in. The range-runner has given way to the stock-raiser. It's like comparing Dan'l Boone to a commercial traveler!"
"I don't quite see how that fits the Lighthouse Service," said Eric, smiling at the Daniel Boone comparison.
"Well, it does to a certain extent. When I first went into the Service, half the coast wasn't protected at all. And even the important lights we had were weak, compared with what we have now. Why, Eric, we've got lights so powerful now that we can't even tell how strong they are!"
The boy looked up incredulously.
"It's an absolute fact," the old inspector continued. "The most powerful light we have is on Navesink Highlands, near the entrance of New York Harbor. It's reckoned at between two million and ten million candle-power. Nobody's been able to measure it. The United States Bureau of Standards was going to do it, but so far, they've left it severely alone."
"How far can that be seen, Father?"
"All depends on the height of the ship's deck from the water," was the reply. "The curvature of the earth determines that. Say, thirty miles on a vessel of moderate size. But the reflection of the Navesink Light on the sky has been seen as far away as eighty miles."
"White light?"
"Yes, white flashing," was the reply.
