but moved on because the town was well defended. A second and bigger boom started after the war. It was during this period that "feather barons", ostrich farmers who had become rich, built most of Oudtshoorn's famously opulent "feather palaces", their houses, most of them on the west bank of the Grobbelaars River. The town grew even more, and in 1904 it claimed 8,849 residents in the census. This boom peaked in 1913, during which year the highest-quality feathers cost more than $32 a pound in 2012 prices. Ostrich feathers were outranked only by gold, diamonds and wool among South African exports before World War I. The market collapsed in 1914, according to The Chicago Tribune, as a result of "the start of World War I, overproduction and the popularity of open-topped cars, which made ostrich-feather hats impractical." 80% of the ostrich farmers were bankrupted, and the ostriches were set loose or slaughtered for biltong. Domesticated ostriches numbered 314,000 at the end of World War I, but had plummeted to 32,000 by 1930. The Jewish population of Oudtshoorn fell from 1,073 in 1918 to 555 in 1936, and only continued to dwindle. For 40 years, Oudtshoorn had been the most important settlement east of Cape Town. The successful agriculture pursuits in the area necessitated an extensive and economically significant train system, which was developed in the 1930s. Despite the periodic irreparability of the Cradock Pass and Attakwaskloof in the Outeniqua Mountains, a reputable trade developed between the inhabitants north and south of the range. There was also trade with Cape Town, but its scope is uncertain; in any case, the poor state of the passes Attakwaskloof and Caledonkloof, through the transverse mountains on either side of the Gamka River, had a disruptive effect on trade with Cape Town. Recent history The end of World War II opened new markets for ostrich leather and meat, and as a result the industry eventually recovered. In the 1940s, two justices of the peace, Ludolph Niepoth Jr. and John O'Connell, were appointed for the Olifants and Grobbelaars rivers, respectively. However, this only relieved the most pressing judicial concerns, and the government was consequently forced to create a local government authority. The production of specialised agricultural seed is the biggest contributor to the region's wealth today, but ostrich farming remains an important business.
