twelve o'clock
There was enough of southing in the wind , to make his last course nearly due south . As he neared the reef , he found that he fell in some miles to the eastward of the islets , -- proof that he was doing very well , and that there was no current to do him any material harm , if , indeed , there were not actually a current in his favour . He next tacked to the northward again , and stood in that direction until near night , when he once more went about . The wind was now so light that he saw little prospect of getting in with the reef again , until the return of day ; but as he had left orders with Jack Tier to be called at twelve o'clock , at all events , this gave him no uneasiness . At the time when the mate lay down to take his rest , therefore , the schooner was quite five-and-twenty miles to windward of the Dry Tortugas , and some twenty miles to the northward of the Florida Reef , with the wind quite light at east-south-east . Such , then , was the position or situation of the schooner . As respects her condition , it is easily described .
