THE SOLVED CIPHER. THE TREASURE OF THE "SAN PHILIPO" Chapter I THE LOG OF THE PRIVATEER "ANNE" "REGGIE, my boy, I have a letter from Uncle Herbert." "What does he say? Has he heard good news about the hidden treasure? "Yes; but wait till after breakfast and you can read it." I almost danced with delight at the information, vague as it appeared, for during the last three months news of my uncle's progress in search of the mysterious treasure that was to restore the fortunes of the family had been disappointingly scarce; and, now that there were indications of a flowing tide in our affairs, it was hard to realize that success might be within measurable distance. My story opens in the year 190--, when I was sixteen years of age, and during the few years that have since elapsed I may truthfully say, without boasting, that few boys have ever experienced a greater amount of peril and adventure than has fallen to my lot in the search for the "San Philipo" treasure.
