Texas Long Leaf Lumber Company
Trinity, Trinity County, Texas
Marker Inscription
In 1907, Thompson Brothers Lumber Company built a mill and 37-acre pond at Trinity. Texas Long Leaf Lumber Company, which started at Willard in 1912, bought Thompson Brothers’ Trinity Mill in 1922. Under management of Paul Sanderson for 22 years, the company was one of the nation’s most successful manufacturers of yellow pine and southern hardwoods. Working with forest landowners in Texas, Sanderson promoted selected cutting, reforestation, fire protection and removal of defective trees. By 1937 the mill was producing 3.5 million board feet monthly. The commercial species of lumber cut were long leaf, short leaf, and loblolly pine, oak, gum, ash, magnolia, and various other woods. The main office of Texas Long Leaf Lumber Company was the 205-acre mill site in Trinity, with additional sales offices in Houston and St. Louis. The company was one of Trinity’s largest employers, with as many as 450 employees. During World War II, production reached 140,000 board feet daily, resulting in lumber flown to Europe and Africa and the awarding of the Army-Navy “E” Award in a march 17, 1944, ceremony in Trinity. Sanderson turned to a widespread public campaign for postwar planning and perpetuation of the timber industry in Texas with emphasis on timber as a renewable natural resource. At the time of his untimely death in October 1944, Sanderson held many civic and lumber industry offices, including President of the Southern Pine Association, President of the Texas Forest Association and Chairman of the Texas Prison Board. In 1953, Texas Long Leaf timber interests totaled 252,230 acres in six East Texas counties. The closing of the mill in 1955 had a devastating impact on the local economy and ended a long chapter in the history of the community.

The Story
East Texas rode a river of pine, and few mills ran it better than the Texas Long Leaf Lumber Company, which bought the Thompson Brothers' Trinity mill in 1922. Under Paul Sanderson's 22-year leadership the operation became a national leader in yellow pine and hardwoods, employing as many as 450 people and pioneering selective cutting, reforestation, and fire protection. During World War II the mill cut up to 140,000 board feet a day—lumber that reached Europe and Africa and earned the coveted Army-Navy "E" Award in 1944. The mill's 1955 closure devastated Trinity's economy and closed a defining chapter in the town's life.
Why it matters
The company embodies both the scale of the Southern timber industry and the early rise of American conservation forestry that reshaped how the nation harvested its woods.
The story behind this marker
AI contextThe era
In the first half of the twentieth century, East Texas ran on pine. The vast forests of the region fed an industry that built houses across the country, and towns like Trinity grew up around the mills that turned standing timber into lumber. This marker tells the story of one of the most important of them, on a site where sawmilling began in 1907 with a company that built a mill and a 37-acre pond to feed it.
The pond was no ornament. In the age of the great sawmills, logs were floated and stored in water to keep them from cracking and to move them easily toward the saws. A 37-acre pond signaled a serious operation, one built to run at scale for decades. When a larger company that had begun operating nearby in 1912 bought this mill in 1922, it inherited an already substantial industrial complex.
The decades that followed spanned the Progressive era, the Depression, and the Second World War—a stretch when American industry was both consolidating and modernizing. This mill lived through all of it, and at its height it was one of the town's largest employers, the kind of enterprise around which an entire community organized its working life.
People & events
The figure at the center of this story led the company for twenty-two years, and under his management it became one of the nation's most successful manufacturers of yellow pine and southern hardwoods. But his real distinction lay in how he thought about the forest itself. Working with Texas landowners, he promoted selected cutting, reforestation, fire protection, and the removal of defective trees—practices meant to keep the woods producing rather than simply stripping them bare.
The numbers tell how large the operation grew. By 1937 the mill was turning out 3.5 million board feet a month, cutting longleaf, shortleaf, and loblolly pine along with oak, gum, ash, magnolia, and other woods. Its main office sat on a 205-acre mill site in town, with sales offices reaching out to Houston and St. Louis, and it employed as many as 450 people—an economic anchor for the whole community.
Then came the war. Production surged to 140,000 board feet a day, and lumber from this Texas mill was flown to Europe and Africa in support of the war effort. That contribution earned the coveted Army-Navy "E" Award, presented in a ceremony in the town in March 1944. Its leader had by then turned to a public campaign for postwar planning and for treating timber as a renewable resource. When he died suddenly in October 1944, he held a remarkable roster of offices, including the presidencies of the Southern Pine Association and the Texas Forest Association and the chairmanship of the state prison board. His interests in Texas timber would later total more than a quarter-million acres across six East Texas counties.
Its place in the American story
This mill embodies two great American stories at once. The first is the sheer scale of the Southern lumber industry, which in the early twentieth century supplied the boards that framed a growing nation. A single mill cutting millions of board feet a month, shipping through offices in distant cities, gives a sense of just how industrialized the harvesting of the Southern forests had become.
The second story is quieter but just as important: the rise of conservation forestry. For much of the nineteenth century, American timber was treated as an inexhaustible resource to be cut and abandoned. The practices championed here—selective cutting, replanting, fire protection, and above all the idea of timber as something that could be grown and harvested indefinitely—were part of a national shift toward managing forests for the long term. That a hard-nosed commercial operation put such ideas into practice made the argument all the more persuasive.
The war years show the same forest woven into the country's fight for survival, its boards crossing oceans to distant fronts. And the mill's closing in 1955, which struck the local economy hard, is a reminder of how completely a town's fortunes could ride on a single industry—and how the end of the great sawmill era reshaped rural life across the South.
If you visit
Come with the pond and the mill site in mind, and let the scale of the place sink in: hundreds of workers, a 205-acre operation, millions of board feet flowing out each month toward Houston, St. Louis, and eventually the battlefronts of a world war. Standing where that once hummed, you can feel how much of the town's daily rhythm was set by the saws.
Think, too, about the ideas that were tested here. The forest around you in East Texas is in many ways a product of the very practices this company helped promote—the notion that you plant and protect as well as cut. Knowing that history can turn an ordinary stand of pines into something worth looking at twice.
This is a landscape for the traveler who likes industry and conservation history and doesn't need a polished attraction to enjoy them. It sits comfortably within a wider tour of the piney woods and their lumber heritage. Read the marker slowly, picture the wartime ceremony that brought the Army-Navy "E" Award to this town, and let the story of a mill that fed a nation—and then fell silent—do the rest.

Waco, Beaumont, Trinity & Sabine Railroad
Trinity, TX
The line that became the Waco, Beaumont, Trinity & Sabine began in 1881 as a humble logging tram, the Trinity & Sabine Railway, and passed through the hands of the MKT and lumber magnate William Carlisle before Col. R. C. Duff bought it in 1924 with Trinity as its hub. Despite its grand name, it never reached Waco, Beaumont, or the Sabine—only Trinity, where it started. At its peak it ran 115 miles of hastily laid track through the piney woods, hauling timber, tomatoes, and later oil, and earned the affectionate nickname "Wobbly, Bobbly, Turnover and Stop" for its frequent derailments. Abandoned in 1961, its restored Engine #1 survives at the Galveston Railroad Museum.
Ranald McDonald House
Trinity, TX
Ranald McDonald settled along the Trinity River after marrying Mollie Turner, daughter of an early Trinity pioneer, and in 1890 hired builder John Denton Gibbs to raise this Victorian house on stone piers. He kept bees, honey, buggies, and wagons here, and his son Alexander later built a power plant on the property that gave Trinity its first electrical system.
Civilian Conservation Corps Camp at Trinity
Trinity, TX
When the Great Depression left young men without work, the Civilian Conservation Corps put them to labor on the land, and one of its camps stood here at Trinity. Company 839 arrived in May 1933 under Captain Charles H. Brammel, settling at this permanent site that June as part of the Lufkin District. The enrollees fought erosion, cut fire lanes, strung telephone lines, and planted millions of pine seedlings that grew into the region's national forests, while gaining vocational skills as mechanics, graders, and blacksmiths. Each man earned thirty dollars a month, most of it sent home to his family.
Glendale Cemetery
Trinity, TX
Glendale grew up near the antebellum Tullos Plantation, and by the time its post office opened in 1887 a small settlement had taken root. The cemetery's earliest graves—a four-year-old girl and an infant, both from 1884—speak to the hard mortality of frontier childhood. Fueled by the J. I. Cameron Lumber Company and the Glendale Orchard Company, the town boomed to some 1,200 residents by 1899, only to fade to about 75 by 1914 as local industry collapsed. Area families have tended the burial ground ever since.
