Bonanza as "Bonanza". In the fall of 1972, off-network episodes were released in broadcast syndication to local stations by NBC under the "Ponderosa" name. After the series was canceled, the syndicated reruns reverted to the "Bonanza" name. From the fourth season on, the Cartwrights and nearly every other recurring character on the show wore the same clothing in almost every episode. The reason for this is twofold: it made duplication of wardrobe easier for stunt doubles (Hal Burton, Bob Miles, Bill Clark, Lyle Heisler, Ray Mazy) and it cut the cost of refilming action shots (such as riding clips in-between scenes),
U Lazy S Ranch split some of the acreage into farms. In 1949, Lott started flying an airplane to drive the cattle and spray herbicide. In the 1950s, the land was faced with a draught. By 1954, Lott planted 1,400 acres of guar to improve the land. He was also the first Texas rancher to use a roto-pitter to break up the rangeland. Two years later, in 1956, Lott's range improvement program had worked. In 1965, Macy split her section of the ranch and renamed it the Running M Ranch. Meanwhile, the U Lazy S Ranch was managed by Lott's son, Jack Lott. By
