The area is bounded to the east by King's Road, to the west by Leighton Road, to the north by Tung Lo Wan Road, and to the south by Caroline Hill Road and Cotton Path.
A prospectus for the new company was issued in August 1897, with J. J. Bell-Irving of Jardines as Chairman of the Board and a capital of $1,200,000. The mill began operation on 1 June 1899 with 12,000 spindles, with an anticipated full capacity of about 50,000 spindles. The company, however, was plagued by set-backs. It closed at the end of 1910. After a time, it was revived only to be forced to close again permanently in 1914, when its machinery was removed to Shanghai and the land and buildings sold for $400,000. The purchasers were the French Sisters of St. Paul of Chartres.
The Order had come to Hong Kong in 1848 and located in Wanchai, where they opened the "Asile de Sainte Enfance" to receive abandoned children. As the years passed, the Wanchai location became increasingly undesirable. In 1908 the Sisters opened a Hospital in Wong Nei Chung valley. In 1914, when they bought the cotton mill premises, they converted some of the mill buildings for their own purposes and later built new and more adequate accommodation for a convent, St. Paul's Convent School, an orphanage, a hospital, and a church.
The same year that Keswick transferred IL 1018 to the cotton mill, he conveyed the remaining part of the valley to Sir Robert Jardine. In time, the land came into the possession of the Government, which used it as sites for the Hong Kong Stadium, the South China Stadium, and a recreation ground.
On the Caroline Hill side of the valley was a large Chinese cemetery. Gravestones and other reminders of the cemetery can still be found among the trees and underbrush.
Five trustees for the Japanese Community acquired a site in So Kon Po Valley in 1911 (Inland Lot 1879). The trustees transferred the site to the Japanese Benevolent Society in 1918. In 1920, the Benevolent Society was merged with the Japanese Education Society to form the Japanese Residents Association. A plot plan of the lot shows buildings that appear to be a temple. The lot is probably the same as that now occupied by the Hong Kong Buddhist Association School.
