The California Silk Center Association was a short-lived 19th century company in the U.S. state of California which encouraged silk culture. It founded what is now the city of Riverside, California. [1] [2] The association was established in November 1869 in Los Angeles, but after the death of its president and only expert in sericulture, Frenchman Louis Provost, in 1870, the silk-growing scheme was abandoned. By then the superintendent of the company had purchased about 5,500 acres (2,200 ha) in the vicinity of Rubidoux Rancho, with a further expansion of 3,169 acres (1,282 ha) already arranged. A number of mulberry trees had been planted to provide nourishment for the silkworms. [1]
To encourage silk culture in California, the Legislature, in 1865–1866 [3] (another source states 1867), passed an act giving a bounty of $250 for every plantation of 5,000 mulberry trees two years old, and one of $300 for every 100,000 merchantable cocoons produced. This greatly encouraged the planting of trees and the production of cocoons. [4]
The California Silk Center Association was formed with a large capital on paper. The association bought 4,000 acres (1,600 ha) which now form part of Riverside. It was the intention of the association to found a colony there of silk growers and silk weavers. Sixty families were reported ready to locate on the colony grounds as soon as negotiations were completed. Prevost, the leader of the group, died shortly after the purchase was made, and the colony project died later. At first, the profits from the seri-culture fad were large, not, however, from the manufacture of silk, but from the sale of silkworm eggs. When the industry was launched, eggs sold at ten dollars an ounce and the worms were good layers. One seri-culturist reported a net profit of US$1,000 an acre made in sixty days from the sale of eggs. Another realized US$1,260 an acre in a single season. The net profits from his three acres of trees and cocoons exceeded the net profit on his neighbor's 10,000 acres of grain. With such immense returns from such small investments, it is not strange that the sericulture craze became epidemic. Mulberry plantations multiplied until the bounties paid threatened the state treasury with bankruptcy; [4] in 1867 [3] or 1868, the law was repealed. [5] Out of the hundreds of thousands of bounty-bought cocoons, only one piece of silk was known to be manufactured, and that was a flag for the State Capitol. Counting bounties paid and labor lost on a non-producing industry, indirectly that flag cost the people of the commonwealth not less than US$250,000. [4]
The dry year of 1869-70 prevented the planting of mulberry plantations. A writer in the Overland Monthly of 1869 noted: "It is almost startling to think that from a calling so apparently insignificant we may be able to realize in a short time a larger sum and infinitely greater gains than from one-half of all our other agricultural productions in the State." Prevost died in April 1870. With the increased supply, the price of eggs declined until it was all supply and no demand. Then the seri-culture epidemic came to as sudden a stop. The worms died of starvation and the bounty-bought mulberry plantations perished from neglect. Of the millions of trees planted, all died. [4] The Silk Center Association sold its land holding to Judge John W. North's Riverside Colony. [6] The experiment failed, but not because California was unsuited to silk culture. The defects were in the seri-culturists, not in the soil or climate of the State. There was no concert of action among the producers. They were scattered from Siskiyou to San Diego. There were not enough producers in any one place to build a factory, and not enough weavers in the country to manufacture the raw silk produced; nor could capital be induced to invest in silk factories.

Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.
Southern California is a geographic and cultural region that generally comprises the southern portion of the U.S. state of California. It includes the Los Angeles metropolitan area as well as the Inland Empire. The region generally contains ten of California's 58 counties: Los Angeles, San Diego, Orange, Riverside, San Bernardino, Kern, Ventura, Santa Barbara, San Luis Obispo, and Imperial counties.
Bombyx mori, commonly known as the domestic silk moth, is a moth species belonging to the family Bombycidae. It is the closest relative of Bombyx mandarina, the wild silk moth. Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk. The silkworm's preferred food are the leaves of white mulberry, though they may eat other species of mulberry, and even leaves of other plants like the osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths, which are other species of Bombyx, are not as commercially viable in the production of silk.
Morus, a genus of flowering plants in the family Moraceae, consists of 19 species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 subordinate taxa, though the three most common are referred to as white, red, and black, originating from the color of their dormant buds and not necessarily the fruit color, with numerous cultivars and some taxa currently unchecked and awaiting taxonomic scrutiny. M. alba is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. M. alba is also the species most preferred by the silkworm, and is regarded as an invasive species in Brazil and the United States.
Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, the caterpillar of the domestic silkmoth is the most widely used and intensively studied silkworm. This species of silkmoth is no longer found in the wild as they have been modified through selective breeding, rendering most flightless and without defense against predators. Silk is believed to have first been produced in China as early as the Neolithic period. Sericulture has become an important cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, Russia, and Thailand. Today, China and India are the two main producers, with more than 60% of the world's annual production.
Edward Digges was an English barrister and colonist who became a premium tobacco planter and official in the Virginia colony. The son of the English politician Dudley Digges represented the colony before the Virginia Company of London and the royal government, as well as served for two decades on the colony's Council of State. Digges served as interim Colonial Governor of Virginia from March 1655 to December 1656, and for longer periods as the colony's receiver general and auditor-general. He is also known for planting mulberry trees and promoting the silk industry in the colony.
Soufli is a town in the Evros regional unit, Greece, notable for the silk industry that flourished there in the 19th century. The town stands on the eastern slope of the twin hill of Prophet Elias, one of the easternmost spurs on the Rhodope Mountains. It is situated in the center of the Evros regional unit, 65 km north of Alexandroupoli and 50 km southwest of Orestiada, on Greek National Road 51/E85 which links Alexandroupoli with Edirne and the Bulgarian border at Ormenio. The town center is only 500m from the Evros River. Soufli is the seat of the municipality of Soufli.
The production of silk originated in Neolithic China within the Yangshao culture. Though it would later reach other places in the world, the art of silk production remained confined to China until the Silk Road opened at 114 BC. Even after trade opened, China maintained a virtual monopoly over silk production for another thousand years. The use of silk within China was not confined to clothing alone, and silk was used for a number of applications, such as writing. Within clothing, the color of silk worn also held social importance, and formed an important guide of social class during the Tang dynasty of China.
Thai silk is produced from the cocoons of Thai silkworms. Thailand's silkworm farmers cultivate both types of the domesticated silkworms that produce commercial silk: Samia ricini, commonly known as the eri silkworm, which produces matte eri silk, and the Bombyx mori, producer of the better known, glossy mulberry silk. The latter is by far the larger silk producer of the two.
Rancho Jurupa was a 40,569-acre (164.18 km2) Mexican land grant in California, United States, that is divided by the present-day counties of Riverside and San Bernardino. The land was granted to Juan Bandini by Governor Juan B. Alvarado in 1838. Located along both banks of the Santa Ana River in southern California, the rancho included much of the land in the present day city of Jurupa Valley, as well as the downtown area in the city of Riverside.
