Mayes's following letters were only a glimpse of how the plans of businessmen had underestimated the Everglades. In long dispatches written at night by candle or lamplight, Mayes described how he and his teenage sons had been taken by boat to Everglades City, a fishing village that had become the supply depot for the road project. From there the men were taken several miles out into the swamp along a crude earthen berm to the worksite. At the end of the line was the monstrous Moneghan dredge, manned and serviced by the laborers. The dredge was an ever-moving, forty- thousand-pound beast sent to dig into the muck and water and tangle of wild jungle that was the Glades. The men cleared the way and the dredge scooped up a deep canal of earth and crushed limestone and piled it onto the ever-lengthening berm that would become the future roadbed.

"It is a horrific and awesome machine," Mayes wrote. "As it digs, its power rattles the very ground for fifty yards in all directions, shaking the world like a mass of jelly."

The workers lived at the work site, sleeping in wooden barracks, and Mayes's first letter from the camp listed the new and exotic dangers.

"At night when the dredge goes silent, the snakes come out from their hiding. Just last night Robert pounded some unknown species to death with his boot heel after finding it in his bedding."

A man called Jefferson was mentioned as the designated sharpshooter, assigned to kill any of "the numerous alligators that creep in while we are in the water trying to move and secure the machinery." In their first two weeks Mayes reported witnessing the death of two workers. One fell from the high dredge rigging and into "a mass of watery muck which quickly sucked him into the earth before any of us could reach him. No attempt was made by the foremen to recover his body and we do not know if the incident was even recorded." The second death was the result of a dynamite explosion, "of which there are several each day to crumble the limestone bed below us for dredging."
