"This isn't anything," he said. "Wait until we strike the edge of the Gulf Stream. Then she's apt to kick up her heels a bit. And you ought to see the Yamacraw! She's got any of these modern dances pushed off the map!"

"I don't mind it," Eric answered, "only it's a different kind of roll. I'm just off the Bear. She rolls enough, but it's a longer sort of roll, not short jerks like this."

"Of course," said the other, nodding; "bound to be. A ship under sail is more or less heeled over and she's kept steady by the pressure of the wind on the sail. The long roll you're talking about isn't the sea, but the gustiness of the wind. That's what makes the long roll."

"At that," said Eric, "it seems to me that the Miami's pretty lively now for all the sea there is."

"There's more sea than you'd reckon," was the reply. "Chesapeake Bay can kick up some pretty didoes when in the mood. You'd never believe how suddenly a storm can strike, nor how much trouble it can make. You see that skeleton lighthouse over there?"

"Yes," said the boy. "Smith's Point, isn't it? I remember learning all these lights by heart," and he rattled off a string of names, being the lights down Chesapeake Bay.

"I see you haven't forgotten the Academy yet," said the other. "Yes, that's Smith's Point Tower. And while it's not a particularly imposing looking sort of building, it's a very important light. It was when they came to build that light, they found out what Chesapeake Bay can be like. Aside from some of the really big lighthouses like Minot's Ledge, Smith's Point gave as much trouble to build as any lighthouse on the United States coast."

"Why?"

"Bad weather and natural difficulties," said the other. "My father was the designer, and because Mother was dead, Father and I used to be together all the time. I was a small shaver of twelve years of age at the time so I was right in the thick of it."

"Tell the yarn," pleaded Eric.
