RUBY MINES , a See also:district in the See also:Mandalay See also:division of Upper See also:Burma, lying along the See also:Irrawaddy See also:river between the See also:Bhamo district on the N., the Shan States on the E., Mandalay district on the S. and See also:Katha on the W. Including the Shan See also:state of Mongmit, which is temporarily administered as See also:part of the district, the See also:total See also:area is 5476 sq. m.; pop. (1901) 87,694. The district geographically forms part of the Shan See also:plateau, and is to a See also:great extent a See also:mass of hills with a See also:general N. and S. direction. It contains considerable See also:numbers of Kachins (13,300) and Palaungs (16,400). The See also:annual rainfall at Mogok averages 98 in. The administrative headquarters are at Mogok, which is also the centre of the ruby-See also:mining See also:industry. It stands in the centre of a valley 4000 ft. above See also:sea-level, and is reached by a See also:cart-road from Thabeikkyin, 6i m. distant, on the Irrawaddy. The Ruby Mines See also:Company employs about 44 Europeans and Eurasians in its See also:works, which are 'situated at the See also:north end of the See also:town. The company has constructed a See also:dam across the Yeni stream and set up an electric See also:installation of about 450 See also:horse-See also:power, which works pumps and the washing machinery. The mines were worked under Burmese See also:rule, but were discontinued on See also:account of the small profit. Now they seem to be established on a See also:sound See also:financial basis.

The See also:

system adopted is to excavate large open pits, from which the ruby-See also:earth or byon is removed en masse and washed and crushed by machinery. Spinels and sapphires are found with the rubies. In 1904, the produce of rubies alone was 200,000 carats, valued at £80,000, most of which were sent to See also:London for See also:sale. In addition, some mining is carried on by natives, working under a See also:licence which does not permit the use of machinery. The district contains 994 sq. m. of reserved forests.
