In addition to the royal monopoly of such objects as have been mentioned, Sir W. E. Maxwell mentions three royal perquisites (larangan raja), i.e. river turtles (tuntong) (by which he no doubt means their eggs); elephants (by which he doubtless means elephants' tusks); [71] and the fruit of the "ketiar" from which oil is made by the Perak Malays. He adds, "It used to be a capital offence to give false information to the Raja about any of these. The 'ketiar' tree is said to affect certain localities, and is found in groves not mixed with other trees. In former days, when the fruit was ripe, the whole of the Raja's household would turn out to gather it. It is said to yield a very large percentage of oil." [72] The only tree in Ridley's list [73] whose name at all resembles the "ketiar" is the katiak, which is identified as Acronychia Porteri, Wall (Rutaceæ). A description of the gathering of the eggs of river turtles by the royal party in Perak will be found in Malay Sketches. [74] Besides the above there are not a few linguistic taboos connected with the king's person, such as the use of the words santap, to eat; beradu, to sleep; bersemaiam, to be seated, or to "reside" in a certain place; berangkat, to "progress"; siram, to bathe; g'ring, to be sick; and mangkat, to die; all of which words are specially substituted for the ordinary Malay words when reference is made to the king. [75] Moreover, when the king dies his name is dropped, and he receives the title of "Marhum," the late or "deceased," with the addition of an expression alluding to some prominent fact in his life, or occasionally to the place of his decease. These titles, strange as it may seem, are often the reverse of complimentary, and occasionally ridiculous. [76] It must not be forgotten, too, in discussing the divine attributes of the Malay king, that he is firmly believed to possess a personal influence over the works of nature, such as the growth of the crops and the bearing of fruit-trees. This same property is supposed to reside in a lesser degree in his delegates, and even in the persons of Europeans in charge of districts. Thus I have frequently known (in Selangor) the success or failure of the rice crops attributed to a change of district officers, and in one case I even heard an outbreak of ferocity which occurred among man-eating crocodiles laid at the door of a most zealous and able, though perhaps occasionally somewhat unsympathetic, representative of the Government. So, too, on one occasion when three deaths occurred during a District Officer's temporary absence, the mere fact of his absence was considered significant. I may add that royal blood is supposed by many Malays to be white, and this is the pivot on which the plot of not a few Malay folk-tales is made to turn. [77] Finally, it must be pointed out that the greatest possible importance is attached to the method of saluting the king.
