They have some wretched sheds for places of worship which they call Langa. During the fast of Sanibayang, which lasts for seven days, they are supposed to abstain from all nourishment. However, at midnight, when they think their god may be napping, they indulge in a hurried meal on the quiet. At the end of their week of abstinence they undergo a purification by bathing, and indemnify themselves for their fasts by several sumptuous banquets. They are forbidden to eat swine's flesh, or drink spirituous liquors, but they are not at all strict in their religion, and the savoury smell of roast pork has been known to overcome their scruples. They are very fond of smoking tobacco, and of chewing buyo; some indulge in opium smoking. Their amusements are gambling, cock-fighting, and combats of buffaloes. Their slave-girls perform various libidinous dances to the sound of the agun, or brass gong, and the calintangang, a kind of harmonium of strips of metal struck by a small drum-stick. The dance called the Paujalay is usually performed at a marriage of any importance, and the young dancers, clad in diaphanous garments, strive to present their charms in the most alluring postures, for the entertainment of the dattos and their guests. They have also a war-dance called the Moro-moro, which is performed by their most skilful and agile swordsmen, buckler on arm and campilan in hand to the sound of martial music. It simulates a combat, and the dancers spring sideways, backwards or forwards, and cut, thrust, guard, or feint with surprising dexterity. The Moros are polygamists in general, although the influence of the Christian women taken as captives and sometimes married to their captors, has, in many cases, succeeded in preventing their husbands from taking a second wife. The cleverness and aptitude for business of Christian Visayas, and Tagal women captives, has sometimes raised them to the highest position in rank and wealth amongst the Moros; and few of them would have returned to their former homes, even if an occasion had offered. The custom of seizing girls for slaves and concubines which has prevailed amongst the Moros for centuries, has of course had the effect of encouraging sensuality, and the morals of Moro society may be compared to those of a rabbit-warren. The Moros do not always treat their slaves with cruelty, they rather strive to attach them to their new home by giving them a female captive or a slave-girl they have tired of, as a wife, assisting them to build a house, and making their lot as easy as is compatible with getting some work out of them. But perhaps the greatest allurement to one of these slaves is when his master takes him with him on a slave-raid, and gives him the opportunity of securing some plunder, and perhaps a slave for himself. Once let him arrive at this stage, and his master need have no fear of his absconding.
