The Truro Company
Following the Onslow Expedition, the strange site on Oak Island lay undisturbed and submerged beneath volumes of water for nearly 40 years. Then, in 1845, fervor for the entombed mystery was reawakened. That year a member of the original dig, Anthony Vaughan, helped form the Truro Company. Together with John Gammell, Adams Tupper, Robert Creelmand, Esq., Jotham McCully and James Pitblado, the treasure-seeking Vaughan anticipated success. Also joining the Truro Company efforts was the brother of the Onslow Company's Simeon Lynds, Dr. David Barnes Lynds (Harris, 1967). With this team, the Truro syndicate represented an impressive collection of qualified and respected individuals.
In spite of the ambition surrounding the newly formed Truro Company, the men did not start further exploration until 1849. With improved funding and organization, the Truro Company began the fourth attempt at solving the Oak Island mystery. In the summer of 1849, the team arrived at the site and continued where the Onslow Company left off; removing water from the pit. After two weeks of laboring against the debris and water of the pit, the crew achieved a depth of 86 feet. These gains, however, did not last. The next day, workers were perplexed to find that the surface of the water had returned to 60 feet (Crooker, 1993).
Decidedly more prepared than their predecessors, the Truro Company was determined to reveal the tunnel's contents, even if human hands did not make the initial discovery. Seeing that the water had returned, the men fashioned a wood platform that they mounted over the mouth of the pit. Through an opening in the floor of the structure, the men plunged a hand-operated auger into the waters below. They hoped this contraption would give them an idea of what was buried beyond the 98-foot deep timber floor. The results of the remote probing could not have been anticipated by even the most optimistic among them (Harris and MacPhie, 2005).
According to Crooker, the auger initially only confirmed information the men already knew (1993). At a depth of about 98 feet, the auger came in contact with a layer of spruce approximately 6 inches deep. Following the log surface, the auger sunk through one foot absent of any material. This was consistent with Vaughan's past experiences with the pit. After every wooden platform, the excavators found a pocket of air from dirt that had settled below. To Vaughan and the others, it would follow that after another nine feet; the auger would again reach a wood surface and repeat the process. Surprisingly, the hand-powered drill delivered very different results.
Beneath the layer of settled dirt, the Truro Company noticed that the auger then penetrated a series of strata consisting of 4 inches of oak, followed by 6 inches of spruce, before entering seven feet of clay. To the crew, the oak and spruce represented more than just a new configuration of wood platforms. After so many failed attempts, this could finally be a chest containing the riches they sought. When the operators withdrew their probe from the pit, they were given even more reason for excitement. Attached to the auger, the men of the Truro Company found three small links of gold chain (Lamb, 2006). Between the wooden object buried beneath the timbers and the metal retrieved by the auger, the men were certain of their victory.
Bolstered by the success of their initial drilling, the Truro Company sent the auger down for another attempt. This time the probe was cast to 114 feet beneath the surface. At this depth, the auger hit another platform of timbers. Although no additional gold was retrieved from this drilling, the device did produce further confirmation of oak and coconut fibers. With the exception of gold coins, the drilling had produced convincing proof that some sort of cache lie buried below.
Perhaps the most convincing evidence that treasure was close at hand was furnished by human behavior amongst the team. According to Lamb, Truro Company foreman James Pitblado did something very peculiar following the fourth drilling (2006). As the auger brought materials to the surface, other crewmembers witnessed Pitblado wipe dirt off an object before discreetly slipping the item into his pocket. Several accounts of the event indicate that immediately after this episode, Pitblado left the island and relinquished all ties to the Truro Company expedition.
Although Pitblado disappeared that day, he would not be absent from the narrative for long. Whatever Pitblado pocketed from the drilling debris had inspired him to petition the provincial authorities for a license to conduct his own excavation on the island. To help back his venture, Pitblado convinced lawyer and recognized businessman Charles Dickson Archibald to join him. Unfortunately for the two, the only official privilege they were granted by the government was the right to continue their search on "ungranted and unoccupied" lands. Essentially, the splinter group of fortune hunters could only seek treasure on property not already deeded to a private owner (Crooker, 1993). This restriction barred the men from exploring the enigmatic Money Pit. After a rejected attempt to purchase the lot containing the pit, Pitblado and Archibald were forced to leave finding the potential riches to the Truro Company. Archibald eventually retired to England while the duplicitous Pitblado and his unknown trophy disappeared into the fog of history.
Despite the promising developments in 1849, the men of the Truro Company left the site for the season. When they returned in the summer of 1850, the team brought with them a renewed sense of purpose and a refined strategy to extract their wealth. Similar to the Onslow Company's second effort, the members of the Truro Company devised a plan that would descend a shaft parallel to the original tunnel. At a depth of 109 feet, the new tunnel would burrow horizontally, thereby entering the Money Pit (Harris and MacPhie, 2005). A daring spelunker would then collect the coffers and return to the surface to celebrate. As could be expected, the island would not succumb so easily.
Similar to previous attempts, before the adjacent access shaft could reach the intended depth, the new tunnel filled with water. While not the result the crew had intended, this episode did offer an important discovery. As the team worked to drain the deluge, the laborers made two valuable observations. First, the water present in the shaft was salty. Second, the level of the water rose and fell with the tide. Although simple, these observations had profound implications. Previously the company thought that the Money Pit was being inundated with water as either part of a complicated trap or as a result of the natural water table. Now the team knew that somehow it was the surrounding sea that flooded their excavations.
Equipped with this new knowledge, the Truro Company investigated the area for more clues. As though a veil had been lifted, the men discovered that a southern portion of the island's shore was actually manmade (Crooker, 1993). The company decided to build a temporary rock dam in Smith's Cove to see if the key to the mystery could be found outside the actual tunnel.
With the water held behind the cofferdam, the crew uncovered remnants of a previous dam as well as five peculiar vent openings. Tracing the vents back to shore, the investigators tried to determine whether the shafts converged into one before continuing inland toward the pit. Here, their suspicions were confirmed. In order to drain the Money Pit, the team would either have to empty the Atlantic Ocean or obstruct the feeder vent that connected the five shafts to the tunnel. They chose the latter. After two attempts to find the feeder vent, the crew succeeded and wedged wood pilings into the shaft to prevent further flooding. Thinking they could now remove the water and claim any treasure, the men were puzzled to find that, despite their best efforts, the water level refused to lower. The confused Truro Company ultimately broke camp and left empty-handed from the 1850 expedition. Deflated and destitute, the company disbanded the following year (Harris, 1967).
The Oak Island Association
In spring of 1861, the next group of hopeful treasure hunters was formed. They were named the Oak Island Association. Under the agreement to give the property owner, Anthony Graves, one third of all findings, the group began work at the Money Pit (Crooker, 1993). At first, the men of the new expedition found the task to be an easier challenge than expected. They soon had cleared the main tunnel down to 88 feet, and had excavated two parallel tunnels to 118 and 120 feet all with no sign of flooding. The 118-foot shaft was dug 18 feet west of the Money Pit. The plan was, at that depth, the excavators would begin tunneling east to access the entombed loot. However, just one foot from penetrating the Money Pit, water flooded the access tunnel (Harris and MacPhie, 2005).
With so little earth between them and the promise of treasure, the Oak Island Association utilized a pumping gin to clear their watery path. After three desperate days of trying to drain the shaft with no results, the company turned their efforts towards the other access tunnel 25 feet from the Money Pit. Already at a depth of 120 feet with no sign of water, the crew determined to burrow horizontally from this new direction. Here again, with the main chamber just feet away, the second access tunnel was inundated with water (Crooker, 1993). For two days, the 63 men of the company struggled to dredge the shaft to no avail.
Down but not out, the team decided to send surveyors into one of the access tunnels in an effort to assess the cause of the flooding. As two men labored in the shaft, those aboveground heard a loud crash. The thankful surveyors made it out alive as water began rushing into the tunnel. With everyone safely at the surface, the crew heard another startling sound. This time it was the Money Pit causing the commotion. According to Harris, beneath the weight of the oncoming water, the timbering installed to support the sides of the Money Pit collapsed everywhere below 30 feet from the opening (1967). Along with the partial wall collapse, further inspection revealed that the bottom of the tunnel had also given way. The depth of the hole now stood at approximately 112 feet.
Although startling, no one was injured during the event. On the contrary, this episode may have helped heal the concerns of the team. As it turned out, when the floor of the Money Pit failed during the flood, pieces of debris from below washed upward through the murky water. When the men inspected the scene, they discovered several curious items including the bottom of a yellow dish, a piece of Juniper worked at either end of the wood, an oak timber, and a spruce slab scarred by the hole left by a drilling auger (Crooker, 1993).
