A maze, a statue, and a riddle

Hints at bottom

John and Jeffrey had been friends for a long time. After meeting at Fort Bragg and serving in the military in the 60’s, they had always remained close, even living in the same town after leaving the military. John had become a journalist. He held a passion for mysteries and puzzles and was known sneak easter eggs into his newspaper articles. Jeff, who always had an knack for art and using his hands, was a local sculptor.

Last year, the owners of a large estate commissioned an elaborate and large hedge maze for their property. They hired Jeff to sculpt a statue for its center. It wasn’t to be of a specific person, but rather simply, just a gentleman with a book. It was an easy enough task for Jeff.

This year, the estate opened the property to the public and the labyrinth of a garden became a sort of town park. It had three entrances, the south side, which faced the mansion, and east and west sides which let out onto two roads entering the estate. There was no entrance on the north side, which faced the property boundary and a patch of woods.

Shortly after it opened, John received a note from Jeff saying, "I hope you get a chance to visit the Maze. I engraved a message which you’ll appreciate. Enjoy the challenge." Curious, John immediately set out, and upon coming to the statue, found these four lines engraved upon the book in the statue’s hands:

Though with much ease have many come to know me,
Just Finley’s breeze from midnight sun shall truly see,
The Victory and Bounty in adventure great and grand,
For vital was my purpose: that unknown southern land.

Intrigued, John looked around the rest of the statue and found these letters engraved about the statue’s collar:

O H R L S B D R A C G D O S

He assumed this was the message Jeff had meant, and a few hours later had uncovered Jeff’s reminiscent line. What message did Jeff write about the statue’s collar?

The [E]ast, [S]outh, and [W]est entrances are marked, along with the center statue, represented by a black square. Green squares represent the hedge, while white squares are open space.
