Cowboys and Cattlemen

Wide open spaces, the hard-working cowboy, his spirited cow pony, and vast herds of cattle are strong symbols of the American West. In 1972 Congress set aside Grant-Kohrs Ranch National Historic Site as a working cattle ranch that preserves these symbols and commemorates the role of cattlemen in American history.

Cattle were introduced to the American Southwest by the Spanish in the early 1500s. British colonists brought cattle to North America's East Coast in the 1600s. Water and land made the difference between farming methods in the East and the open-range methods of the West. In the East abundant rainfall created pastures that could support large herds of cattle. Some western lands received fewer than 10 inches of rainfall a year and required over 100 acres to sustain each cow.

Before barbed wire, stockmen couldn't fence enough acreage to support livestock. Instead, a system of open-range grazing evolved. Cattle were turned out on public land and left to graze wherever they found grass. Limited in their roaming only by rivers, rough country, or waterless stretches, the cattle might spread over a million acres. Cattle from many owners mingled, leading to the establishment of roundup associations and grazing districts. As the open-range system expanded north from its roots in the Southwest, American cowboys learned herding, roping, and other skills from the Spanish vaquero, even adapting that word to buckaroo.

Cattle Barons—a New Breed of Entrepreneur
In the mid-1800s mining, timber, land, and business opportunities brought a flood of immigrants and fortune seekers west. The transcontinental railroad, completed in 1869, helped expand industries. Burgeoning towns in the West and East needed food, and a new style of businessman took hold—the cattle baron. Johnny Grant and Conrad Kohrs were among them. In 1859 Grant drove 400 cattle from Deer Lodge Valley, Montana, to Sacramento, California. By the 1880s Kohrs was shipping 10,000 cattle annually by rail to stockyards in Chicago. But the rapidly expanding cattle industry had problems. Harsh weather, disease, rustling, economic fluctuations, homesteaders, and fencing took their toll on what had begun as a get-rich-quick scheme.

Cattlemen adapted. Each state had its stockgrowers association, with a national association looking after their interests in Washington, DC. Research found causes of devastating cattle diseases, and vaccines decreased losses from them. State and federal legislation and programs came to regulate the industry. Land management changed, too. Grazing on public land—free in the boom years—became subject to fees. Many open-range cattle outfits faded as the West became settled, fenced, and farmed. Yet even today, cattle graze on hundreds of thousands of acres of public and private land in the West—and the American cowboy still rides.

Jesse Chisholm (1805-68)
Scot-Cherokee, famous interpreter, trader. He traveled to his trading posts on a trail that became his namesake. This trail carried nearly half of all cattle driven from Texas to Kansas.

Oliver Loving (1812-67)
Trader, pioneer of cattle drives. He sent first herd of Texas longhorns to a northern market in 1858. This venture was successful, so he traded for more cattle, building large herds for market.

Charles Goodnight (1836-1929)
Cowboy, cattle baron, founder of JA Ranch in Texas, inventor of chuck wagon. In 1866 he and Loving, 18 cowboys, and 2,000 longhorns blazed a new trail from Texas to Denver.

Capt. Richard King (1824-85)
Livestock capitalist, founder of King Ranch in Texas. He supplied beef and provisions to Confederates during Civil War and used his war profits to amass nearly one million acres.

John Chisum (1824-84)
Cattleman. His empire bordered 150 miles of the Pecos River in New Mexico. By 1875 over 80,000 cattle bore his Jinglebob earmark—an ear notch that caused a portion to dangle.

John Wesley Illiff (1831-78)
Merchant, cattleman, banker. In 1870s his business sold beef to railroad crews, miners, and Indian agencies. He could ride all week (one way) without leaving his ranch lands in Colorado.

Granville Stuart (1834-1918)
Co-owner of DHS Ranch. In 1883 Bielenberg and Kohrs bought a major part of the ranch, the largest cattle deal to date in Montana. His journals include drawings of Montana life.

Conrad Kohrs (1835-1920)

Dream back beyond the cramping lanes to glories that have been—the camp smoke on the sunset plains, the riders loping in: Loose rein and rowelled heel to spare, the wind our only guide, for youth was in the saddle there with half a world to ride.

—From The Passing of the Trail by Badger Clark, poet of the American West and Poet Laureate, South Dakota, 1937-57

Life of the Cowboy

Often small and wiry, usually in his teens or early twenties, the open-range cowboy craved the adventure of trailing cattle hundreds of miles and the challenge of rounding up half-wild stock on the unfenced range. The work was hard—a long day in the saddle and watching the herd at night, with no days off. But it was balanced by companionship, hearty meals at the chuckwagon, and the promise of $30 or $40 at the end of a long cattle drive—plenty for a trip to town.

From his high-crowned hat and silk bandana to his leather chaps and jingling spurs, a cowboy's outfit proclaimed him part of an independent breed. The horses he rode may have belonged to his employer, but his saddle was his own—an item of such pride that to say he had "sold his saddle" meant his cowboy and trail days were over.

Written in Fire—Brands and Ownership

A rancher's brand was his reputation, his cowboys' pride, and his cows' return address. More than 50,000 brands were registered in Montana by 1900. When cattle from different owners mix together there must be a way of identifying them, and a registered brand is as individual as a license plate.

During open-range days, tens of thousands of animals from hundreds of owners mingled on common ranges. Each spring ranchers worked together to gather all the cattle in a roundup district. Cowboys heated the rancher's branding irons in a fire. When an unbranded calf was separated from the bunch, its mother naturally came to protect it. Her brand was called out and that iron taken from the fire and applied to the calf. The calf was also earmarked, a specific notch cut into its ear for extra identification. Today 98 percent of Montana cattle are still branded, but earmarking is rarely practiced.

Kingdom of Cattle

Conrad Kohrs was the Cattle King of Montana, but it was a kingdom without borders and his subjects were the cattle that ranged freely across millions of acres of public land. Born in Germany in 1835, Kohrs left home at 15 and sailed the world as a cabin boy. The quest for gold led him to California, Canada, and, in 1862, that part of the Idaho Territory that would become southwest Montana. There he made his fortune—not by panning for gold but by raising cattle.

Other cattlemen preceded Kohrs onto the open range, and many others would follow. Johnny Grant and a handful of other early settlers had been wintering cattle in Montana's western valleys since the 1850s. Grant crossed paths with Kohrs soon after the younger man arrived in the area.

Conrad Kohrs came into the territory with only the clothes on his back and what he could carry in his bedroll—and he needed money. He had learned the rudiments of the butchering trade from relatives in New York and Iowa, and he quickly found work as a butcher's assistant. Kohrs soon owned butcher shops in many gold camps. Johnny Grant supplied cattle to his shops, and, in 1866, sold his ranch to Kohrs. Grant moved back to his native Canada, leaving a legacy of stock-raising in the sheltered, grassy valleys of southwest Montana that Kohrs carried on.

Conrad Kohrs began building his empire in Deer Lodge Valley. In time he acquired 30,000 acres at the home ranch, where he raised fine breeding stock, both cattle and horses. When the near-extinction of bison on the northern plains opened a sea of grass to cattlemen, Kohrs ranged cattle from Colorado to Canada, sharing these scattered ranges with other stockmen. The shared nature of the range required close cooperation among all cattlemen and led Kohrs and other ranchers to found the Montana Stockgrowers Association in 1884.

For the next quarter of a century Kohrs and his half brother, John Bielenberg, were influential in the evolution of the cattle industry and the politics of Montana. Kohrs was a delegate to Montana's constitutional convention of 1889 and helped draft the constitution that led to statehood.

As the open-range system declined, Kohrs adapted his business to a mix of farming and open-range grazing. In 1909, long after the boom years, Kohrs' cattle sales topped $500,000. In later years he sold off most of his holdings, having achieved his version of the American dream. Conrad Kohrs died in 1920, and John Bielenberg in 1922. For a time the ranch was run by a family trust. In 1932 Kohrs' grandson, Conrad Warren, began a new era as manager and then, in 1940, as owner of the ranch.

Settling the Valley

The mountain valley Johnny Grant settled in 1859 was a land caught between eras and cultures. Considered Flathead (Salish and Kootenai) territory by the federal government the valley had long been used by many tribes as a route to hunting and trading areas. Early pioneers that settled in Deer Lodge Valley were Mexican and Métis, a cultural blend of French-Canadian and tribal people, attracted by fur trading. As the fur trade faded into memory, gold mining and livestock industries attracted new settlers.

Johnny Grant (1831-1907)
His marriage to women of several tribes helped ensure his peaceful settlement in the valley.

Powerful Partnerships

John Bielenberg was Conrad Kohrs' younger half brother and a full partner in their diverse business interests. Kohrs spent much of his time on mining, water rights, banking, and the public life of an entrepreneur. Bielenberg concentrated on the daily management of their cattle empire. He sought to improve the breeding of horses and cattle. Crossing Thoroughbred studs with native mares, he bred cow ponies famed for stamina. His 1900 observation about cattle, "Herefords are the coming breed for Montana," was prophetic.

John Bielenberg (1846-1922)
John Bielenberg was Kohrs' half brother and business partner, and an expert cattleman. He lived in the ranch house for half a century, but he often preferred the informality of the bunkhouse.

Furthering a Legacy

Conrad Kohrs Warren was born into one of the most famous ranch families of the 1800s, but the days of open range and cattle drives were over. When he began managing the Kohrs ranch in 1932, only 1,000 acres and a few hundred head of cattle remained. He ran the ranch with methods of the new century while honoring his family's ranching legacy. In 1952 he was elected president of the Montana Stockgrowers Association that his grandfather helped found 66 years earlier.

Conrad K. Warren (1907-1993)
Warren was renowned for his love of animals, commitment to the livestock industry, and resolve to preserve the ranch, artifacts, records, and lore of his grandfather and great uncle.

Home on the Range

There was not just one home on the range but many, from a simple dugout gouged out of a hillside and faced with rough-hewn logs to the elegant mansions of the cattle kings. Johnny Grant described his first home in the valley as a leather lodge (a tepee) that he got from an Indian in exchange for a horse. Conrad Kohrs called his first butcher shop a brush shanty. Each must have felt pride in his new home, from the original 4,000-square-foot house that Grant built in 1862 to the 5,000-square-foot brick addition Kohrs built in 1890.

Augusta Kohrs came to a finer home than many pioneer brides. Still, when she arrived in 1868, the interior of the house was a far cry from its later Victorian elegance. The bride discovered a house with bare floors, spittoons, and an old bed strung with rawhide in place of springs, and a straw-filled sack for a mattress infested with bedbugs. She began "a war of extermination" using boiling water and kerosene until the bugs disappeared except for "an occasional one left by a chance traveler." Over time she acquired fine furniture, a piano, china, silver, gilt-framed pictures, and Persian rugs. The 1890 addition of her conservatory filled her heart with joy.

Shelter, warmth, companionship, and food were essentials for frontier life. If the Kohrs served champagne and oysters to guests on special occasions, it is likely that a hungry cowboy riding the grubline ate with no less enjoyment when invited into the bunkhouse for coffee, beef, beans, and biscuits. Amusements were similar too. Kohrs played cards with his friends on a special felt-covered poker table, while out in the bunkhouse cowboys played cribbage and cards over a scarred worktable, and on the open range cowboys dealt cards across a blanket on the ground.

For ranchers less prosperous than the Kohrs the line between family and hired hand wasn't always so obvious. They spent much time together. Work filled their days; songs, stories, and conversations filled idle hours. Chores were necessary for comfort, even survival. One element missing from both bunkhouse and open range was family. For many cowboys, some little older than children themselves, roundups and trail drives were often their first time away from home. Theirs could be a lonely life.

Old World Meets New

Her childhood in Hamburg, Germany, did little to prepare Augusta Kruse Kohrs for her life as a pioneer bride. She milked cows, made soap and candles, cooked, and kept house for hired hands and her husband. Yet she preserved much of the heritage of her former homeland. As the family prospered she acquired fine belongings, supervised a staff, and valued both the New and the Old World, balancing the opportunities of America with the music, art, and culture of Europe.

Augusta Kohrs (1849-1945)
Proud, tall, and beautiful, 25-year-old Augusta poses for a portrait. She and Conrad met when children in Germany. They married in Iowa on February 23, 1868, after dating for about three weeks.

A Frontier Family

The upbringing of the Kohrs children differed from that of many ranch children. They had a governess, learned German, and traveled abroad. Chores common to many children—chopping wood, pumping water, feeding livestock—were not part of their routine. Anna and Katharine learned needlepoint; William showed a talent for art. Anna kept close ties with ranching by marrying John Boardman, a rancher associated with Kohrs in livestock enterprises. In the end it was Katharine's son, Conrad Warren, who saved the ranch and was most at home on the range.

Preserving a Way of Life

Sometimes it takes someone from outside the story to see the importance of a family's history. It was Nell, Conrad Warren's wife, who began recording the family history she had learned from Augusta. Nell cared for their extraordinary collection of antiques and documents, while her husband concentrated on ranching in difficult times that included the Great Depression and World War II. She also urged her husband to contact the National Park Service as they sought to preserve the historic Grant-Kohrs ranch beyond their lifetimes.

Nell Warren (1911-79)
Nell protected the possessions of Kohrs and Bielenberg, and compiled a history of their businesses. Her efforts preserved a rare, intact record of the cattle industry that spans nearly 150 years.

Moseying Around: The Ranch Today

Exploring the Grounds You are invited to tour the ranch on your own. Please notice that firearms are prohibited in the visitor center and buildings 1, 4, 10, 11, 15, and 16.

Take time to notice little things—feel fresh air on your face, listen for birds, count colors in the sky and fields, observe textures of wood and leather, smell the aroma of horses and hay.

Beyond the Clark Fork River (named for William Clark of the Lewis and Clark expedition) rises the Flint Creek Range, with Mount Powell the highest at 10,200 feet. In winter these mountains catch much of the eastbound storms, leaving the valley relatively free of snow. This is one reason why Grant and Kohrs settled here—their cattle and horses could graze all winter in "this luxuriant grassy valley."

Ranch House (1862-90)
Johnny Grant built the white portion of the house in 1862. It was a trading post downstairs and a residence upstairs. In 1890 Conrad Kohrs built the brick wing with a formal dining room, large kitchen, a second bathroom, and bedrooms. Augusta Kohrs acquired elegant furnishings over several decades. Coal to heat the house was stored in the shed behind the back door of the brick addition.

Bunkhouse Row (1907-1930s)
Cowboys and ranch hands ate and slept here and whiled away evening hours swapping stories, mending gear, and playing cards.

Ice House/Tack Room (1880s-1930s)
Ice cut from ponds in winter was stored here for summer use. When refrigeration came in 1935, the ice house became a tack room for horse gear. The added room was the summer home of Ham Sam, the Chinese cook.

Garage/Blacksmith Shop (1935)
Conrad Warren stored gas-powered vehicles here. It also served as a repair shop and a place to shoe horses.

Leeds Lion Barn (1885)
There are several stallion barns on the ranch, each with its own hay loft and corral. To prevent fighting each barn stabled only one stallion. This barn was named for a famous English Shire draft horse stallion owned by Kohrs.

Feed Lot and Sheds (1930s)
Con Warren added this part of the ranch when he began raising Hereford cattle.

Buggy Shed (1883)
This shed once adjoined the east end of bunkhouse row. It was moved in 1907 to make way for the railroad tracks.

Granary (1935)
Grains (oats, corn) were ground and mixed for cattle feed, then stored here.

Thoroughbred Barn (1883)
Kohrs built this as a stable for Thoroughbreds. Conrad Warren used it for his show cattle. Today it houses horse-drawn vehicles and equipment original to the ranch.

Chicken Coop (1930s)
Chickens provided meat and eggs. Hens laid eggs in nesting boxes, pecked for food in the yard, and perched on roosting bars at night.

Draft Horse Barn (1870)
Kohrs and Bielenberg raised several breeds of draft horses—Shires, Percheron-Normans, and Clydesdales—to do the heavy chores.

Dairy (1932)
Dairy cows were milked here. In the 1930s Conrad Warren sold milk to Deer Lodge Creamery.

Oxen Barn (1870)
After draft horses replaced oxen, this barn sheltered other livestock but kept its name.

Bielenberg Barn (1880)
Young cows having their first calves were often kept here so that ranch hands could make sure the calving (birthing) went well.

Warren House (1934)
Conrad and Nell Warren's house was a wedding gift from Conrad's grandmother, Augusta Kohrs. Today it holds park administrative offices.

Warren Barn (1950s)
The barn housed hay, grain, and Con Warren's prize Herefords.

Beaver Slide Hay Stacker
In August, this horse-run stacker piles hay into 50-ton stacks.

Railroad Tracks
Utah Northern Railroad arrived in 1879; the Milwaukee Railroad came in 1907.

Look for three styles of fences: Pickets enclose the ranch house; boards and barbed wire mark pastures; jacklegs (rails on crossed posts) were the main style on early Montana ranches.

Irrigation Ditches
The Kohrs-Manning Irrigation Ditch dates from the 1870s.

Ask at the visitor center for maps of the nature trail, the Old Milwaukee Trail, or the trail to far pastures.
