"The boat is to be here at half-past eight," was the reply, "and we're going to find the most beautiful spot that there is in the submarine Garden of Eden. Our darky boatman, 'Early Bird,' they call him, says he knows a place quite far out on the reef where there are wonderful groves and parterres unspoiled by tourists because they lie so distant that it is not worth while for the excursion boats to make the trip."

"I don't quite see," said Colin, "how the visit of tourists floating over a stretch of sea could harm the seaweeds and the coral growing on the bottom."

"But it does, because a number of the glass-bottomed boats carry a diver who goes down and breaks off specimens of coral at the tourists' request, selling them for a good sum. But the gardens to which we are going, I understand, are entirely out of the beaten track and are very much finer besides. Here is 'Early Bird' now."

As he spoke, a white sailboat with a large spread of sail came skimming into the little bay, heading for the private wharf of the hotel at a rapid clip. Colin held his breath as the craft came rushing in, for the inlet was not much wider than twice the length of the boat and it seemed certain that the vessel would crash full upon the rocks not twenty feet beyond the wharf. But at the very last second the tiller was put over, the sail jibed, and as gently as though she had crept up in a calm, the Early Bird glided up beside the wharf, her bowsprit narrowly missing the bushes on the bank as she turned.

"You sure can handle a boat!" cried Colin admiringly.

The owner of the vessel, a young colored man, of good address and with a clever face, showed his white teeth in a gratified smile as he replied:

"Yas, sah, Ah've sailed a boat roun' the harbor quite a good deal."

"It looked that time as though you were going to be smashed up, sure."
