Their taste in jewellery is remarkably restrained. The rich wear silver or gold buttons in their ears. Of the poorer classes some confine their personal embellishment to copper nails and others wear a plait made of coloured threads which falls over their shoulders. We sometimes noticed bracelets on the wrists of some of the girls. This ornament serves to remind its wearer of the temporary vow of chastity which she has taken to guard her against some danger or cure an illness.
Others again wear a necklace of large amber beads from which hangs the Tamrak, a kind of amulet which wards off the powers of evil. This indispensable talisman consists of a small cylinder of lead on which a priest has traced mystic characters with a sharp-pointed instrument.
Both sexes keep their hair long and, like the Annamites, twist it into a knot at the back. The men wear as head-dress either a large turban or sometimes merely a kerchief. Pockets are unknown, but two purses hung from a long girdle provide an excellent substitute.
In early times the Cham princes set up their royal residence and the seat of government in Phanrang. In the seventeenth century their office was still hereditary, but the Court of Hué reserved the right of investiture. In the nineteenth century successive invasions undermined the authority of those potentates and all appointments to administrative offices were made by the Annamite conquerors, who made their selection among the local aristocracy.
The Cham of Cambodia are all Mohammedans, but of those of Annam about two-thirds have remained Brahmins. Their countrymen of the later faith call them "Kaphirs" (infidels), and reserve to themselves the title of "Bani" (sons of the faith). Nevertheless, there is perfect toleration between the followers of the two religions. The priests honour with their presence the ritual ceremonies of the group whose beliefs they do not share and neither party attempts to make converts of the adherents of the other.
The calendar of the Cham is partly lunar and partly solar. The beginning and end of each month coincides with a new moon. As in the Hindu calendar, this lunar month has a light half which culminates in the full moon and a dark half which is terminated by the new moon. The duodenary cycle is employed for the purpose of measuring time. This system was invented by the Turks, but the Chinese have been mainly instrumental in securing its adoption throughout the Far East. Each of the twelve years of which it is composed is called by the name of some animal—Rat, Buffalo, Tiger, Hare, Dragon, Snake, Horse, Goat, Monkey, Cock, Dog, Boar.
The year begins in April-May and comprises twelve lunar months of thirty and twenty-nine days alternatively. They are numbered from one up to ten, but the eleventh and twelfth have special names. Every three years a month is added, and it may well be imagined to what difficulties and disputes this proceeding gives rise in the absence of agreement between the villages.
There are seven days in the week. Their names are borrowed from the Sanscrit and, like ours, represent a planet. Each day has twelve hours, twice the length of ours, of which the first begins at cockcrow. The night consists of five watches.
These are the component parts of the system in which it is quite simple to calculate any date. For example, a document may be dated thus: "Signed, Monday the fourth day of the light half of the fifth month of the year of the Dragon."
It is probable that in early times the Cham computed time by a system similar to that of the ancient Javanese, a people with whom they maintained close political and commercial relations, as witness several alliances between members of the two reigning houses. The Javanese calendar comprised a week of five days, a month of six weeks, a year of ten months, each with its special tutelary deity.
