The Old Rock House
Sylvester vicinity, Fisher County, Texas
Marker Inscription
In the 1880s Andy Long (b. 1850) began acquiring his 10,300-acre spread known as the "OB" Ranch. His landholdings surrounded what is now the town of Sylvester. This one-room rock house, built in 1883, served as ranch headquarters. Long stayed here while he was in the area working his cattle but maintained a home for his family in Sweetwater (25 mi. SW). The Old Rock House at times also served as living quarters of the ranch foreman. Andy Long sold the "OB" Ranch in 1901 to the Compere brothers for the purpose of colonization. (1984)

The Story
In the 1880s cattleman Andy Long assembled the 10,300-acre "OB" Ranch that surrounded the future town of Sylvester. This one-room rock house, built in 1883, served as ranch headquarters and sometimes as the foreman's quarters, while Long kept his family home 25 miles away in Sweetwater. He sold the ranch in 1901 to the Compere brothers for colonization.
Why it matters
The little rock house is a surviving relic of the open-range ranching era that gave way to farm colonization across West Texas.
The story behind this marker
AI contextThe era
In the 1880s the rolling plains of West Texas were changing fast. Only a few years earlier the region had been the domain of Plains Indian nations and the vast buffalo herds. The buffalo were destroyed, the Native peoples were forced onto reservations, and cattlemen moved quickly into the grasslands left behind.
It was the heyday of the cattle kingdom. Ranchers assembled enormous holdings, and railroads pushing across Texas gave them a way to get cattle to distant markets. Towns grew up along the rail lines as shipping points and supply centers, and a rancher might spend most of his time out on the range but keep his family in the nearest town.
That era did not last long. Barbed wire, drought, hard winters, and falling cattle prices all reshaped ranching in the late nineteenth century. By around 1900, land that had grazed cattle was increasingly being divided into farms, as promoters and colonization companies brought in settlers to plow the plains.
People & events
Andy Long, born in 1850, came of age just as the West Texas range opened up. In the 1880s he began putting together the 10,300-acre spread known as the "OB" Ranch, land that surrounded the spot where the town of Sylvester now stands. Assembling a ranch of that size took years, and it made Long a significant figure in the area.
In 1883 this one-room rock house was built to serve as ranch headquarters. It was a working building, not a family home. Long stayed here when he was in the area working his cattle, while his family lived about 25 miles to the southwest in Sweetwater. At times the ranch foreman lived here too, keeping an eye on the operation while the owner was away.
In 1901 Long sold the "OB" Ranch to the Compere brothers, who bought it to colonize it, opening it to new settlers. With that sale, the ranch's story became part of a larger change: the shift from big cattle spreads to farms and small towns that reshaped this part of Texas.
Its place in the American story
The Old Rock House is a small witness to one of the great transitions in the American West. In just a few decades, the Great Plains went from buffalo range to cattle range to farmland. This building stood through two of those three stages.
The ranch's history, assembled in the 1880s and sold for colonization in 1901, follows a pattern repeated across Texas and the West. The famous open-range cattle boom was short, and much of the ranchland eventually became farms and farm towns. Land sold for colonization was how many towns on the plains came to be settled.
Simple, sturdy buildings like this one are also a reminder of how people actually lived. In popular memory, the cowboy West is all saddles and trail drives. The day-to-day reality involved headquarters like this: a single stone room built to last on a treeless plain, where cattle were tallied and bosses and foremen came and went.
If you visit
Look at the building's size first. One room of rock was enough to serve as headquarters for a ranch of more than ten thousand acres. Stone was a practical choice on a plain where good timber was scarce, and a stone building could stand up to wind, heat, and time. More than a century later, it still does.
Try to imagine the country around you as open range, with no town nearby. The marker notes that Long's land surrounded what is now Sylvester, so the community you drive through grew up largely on ground that was once cattle range.
The Old Rock House is a good stop on a West Texas road trip, especially paired with Sweetwater, where Long kept his family home. Driving between the two gives you a sense of the distance a rancher traveled to reach his cattle. Respect any private property, and enjoy the wide sky that made this ranching country.

Woods Chapel Cemetery
Roby vicinity, TX
As settlers pushed into this corner of Fisher County in the early 1880s, a single frame building served as both school and church, and by 1884 a graveyard had begun — named for its first pastor, J. B. Woods. Among those resting here is the family of Henry Clay Lyon, a Tennessee-born veteran of the Republic of Texas army; of twenty-six marked graves, thirteen belong to infants and small children.
Newman Community and Cemetery
Sylvester vicinity, TX
Rancher Jim Newman, one of Fisher County's earliest settlers, established a spread here around 1879, and the community that grew nearby took his name when the county's first post office opened in 1881. By the early 1900s Newman had schools, churches, and a store, and its cemetery—set aside in 1906—holds sixteen veterans, including Civil War soldier R. L. Creswell. As population steadily declined, the churches and school closed one by one, leaving the still-active cemetery as the town's last trace.
Organization of Fisher County
Roby, TX
The Texas Legislature created Fisher County in 1876, but with no permanent settlers it was attached to neighboring counties for the courts. By 1885 enough people had arrived to organize the county, touching off a fierce rivalry between the rival townsites of Fisher, promoted by Wisconsin businessman E. D. Strang, and Roby, laid out by former Mississippi planters D. C. and M. L. Roby. An 1886 election made Roby the county seat, and with a courthouse underway the county's organization was complete.
Fisher County
Roby, TX
This region was crossed by an old Indian trail running from Mexico to the Texas frontier settlements, and in 1856 Colonel Robert E. Lee — then commanding the U.S. Second Cavalry, years before he led the Confederate army — campaigned against Native peoples here. Fisher County was carved from Young and Bexar territories, created in 1876 and organized in 1886, and named for Samuel Rhoads Fisher, a signer of the Texas Declaration of Independence and Secretary of the Navy of the Republic. Its seat, Roby, took its name from local landowners.
