The Middle Valley Trap Rock & Mine Company
The mining industry at Teetertown began in 1896 and was typical of the highly mechanized methods used widely in the northeastern U.S. during the Victorian Era. Strategically spaced, 2-1/4' wide, by 6"(+/-) deep holes were first drilled into the rock face, with drills powered by a 150 horsepower steam engine. Dynamite was then carefully packed deep into the holes, with paper/gunpowder fuses providing sufficient time for workers to clear the site. The ensuing blast would dislodge tons of rock, to be crushed into smaller stones and gravel, as needed. The quarried stone was subsequently loaded into ore carts, which were winched up the hill over small-gauge rails by a 3/4"
Rock quarry drilling and blasting were considered a dangerous art form. The pattern of holes drilled, and the amount of dynamite used, determined the amount of rock to be dislodged. - - and just where it might fall. If too few holes were drilled or too little dynamite used, time and money would be wasted - - BUT, if workers misjudged the drilling pattern, hole depth, or underestimated the amount of dynamite, the results could be fatal!
One of the worst tragedies that occurred at the quarry was on November 12, 1904, when 21 year-old Anthony Trimmer (1883-1931), his father's personal business representative, and his brother, 20 year-old Grover Cleveland Trimmer (1884-1904), decided to work that frigid Saturday morning. Grover stored his lunch container in the boiler house, while Anthony stored his in the blacksmith shop. The weather created a problem with blasting operations, so two sticks of dynamite were brought inside the boiler house to keep dry, a safe distance from the low flame of the boiler. As lunch approached, Grover asked his brother to join him for conversation in the warmth of the boiler house; Anthony agreed and went to retrieve his lunch. Suddenly, as he walked toward the structure, the boiler house exploded, knocking him to the ground. The vibration of the blast was so loud that it shattered windows of nearby homes.
Quickly, Anthony and the quarry workers ran to Grover's aid as debris from the boiler house lay on top of him. Frantically, they removed him from the wreckage by hand. His body was badly burned and mangled. Unconscious, he was placed onto a wagon and driven to his parents' home where he succumbed to his injuries several hours later. Funeral services were conducted in the parlor among friends and family. Grover was buried in the Lower Valley Presbyterian Church cemetery. His father never recovered from the tragedy; he died five years later and was buried next to his son. Another son of Lawrence Trimmer, Lamont (1881-1965), continued to operate the company until a dwindling customer base and financial problems forced it to cease production in 1923.
