“It’s a thought. The ship anchored near an island at the mouth of a wide river. He describes the water as more brown than blue.”

“I noticed the muddy quality of the water when we set out today,” Zavala said. “We passed an island near Aberdeen Proving Grounds.”

Austin still carried the Chesapeake Bay chart in a plastic map pouch. He unfolded the creases and spread the chart out on the floor. Borrowing a grease pencil from Saxon, he marked an X near Havre de Grace at the mouth of the Susquehanna. “We’ve got our Phoenicians cooling their heels here. What did they do with the cargo?”

“Maybe they hid it in a gold mine,” Saxon said.

“Your book suggested that Ophir was located in North America. Are you saying that this thing was hidden in King Solomon’s mine?”

“When I first started looking for Solomon’s mine, I concentrated on the area around the Chesapeake and Susquehanna,” Saxon said. “There was extensive gold mining within walking distance of Washington a hundred years before the big California Gold Rush of 1849.”

“We know that,” Austin said.

“Thelma Hutchins mentioned that her husband was aware of the gold mines,” Zavala said.

Saxon nodded. “There were more than a half dozen mines along the Potomac, from Georgetown past Great Falls, around the turn of the century. At least fifty mines operated in Maryland on both sides of the Chesapeake. The gold was found in rocks from the Piedmont Plateau, which runs from New York to South Carolina.”

“That’s a lot of territory to cover,” Austin said.

“Agreed. I started looking for evidence of Phoenician contact. I found it not in Maryland but farther north, in Pennsylvania. A cache of stones with Phoenician writing on them was discovered near the state capital at Harrisburg.”

“What sort of stones?” Austin said.

“A man named W. W. Strong collected around four hundred stones found near Mechanicsburg in the Susquehanna River valley. Dr. Strong interpreted the markings on them as Phoenician symbols. Barry Fell thinks the writing is Basque. Others say the markings are natural.”

“Hold that thought,” Austin said. He went out to the Jeep and returned with the stone he had retrieved from the wreck. Saxon’s jaw dropped to his Adam’s apple.

“Where on earth did you get that?”

“I brought it up from my dive on the shipwreck.”

“Astounding!” Saxon said. He took it from Austin, holding it as if it were made of glass, and traced the inscribed line with his finger. “This is Beth, the Phoenician symbol for house, later to evolve into the Greek B. It ties the wreck into Mechanicsburg.”

Austin drew a second X at the wreck site in the bay, and a third at the mouth of the river. He connected the Xs with a line and extended it up the river.

“The trail grows cold at Mechanicsburg,” he said.
