A few additional examples of natural derivation may still further emphasize the point just discussed. In Bambarese the word for 10, _tank_, is derived directly from _adang_, to count.[158] In the language of Mota, one of the islands of Melanesia, 100 is _mel nol_, used and done with, referring to the leaves of the cycas tree, with which the count had been carried on.[159] In many other Melanesian dialects[160] 100 is _rau_, a branch or leaf. In the Torres Straits we find the same number expressed by _na won_, the close; and in Eromanga it is _narolim narolim_ (2 x 5)(2 x 5).[161] This combination deserves remark only because of the involved form which seems to have been required for the expression of so small a number as 100. A compound instead of a simple term for any higher unit is never to be wondered at, so rude are some of the savage methods of expressing number; but "two fives (times) two fives" is certainly remarkable. Some form like that employed by the Nusqually[162] of Puget Sound for 1000, i.e. _paduts-subquaetche_, ten hundred, is more in accordance with primitive method. But we are equally likely to find such descriptive phrases for this numeral as the _dor paka_, banyan roots, of the Torres Islands; _rau na hai_, leaves of a tree, of Vaturana; or _udolu_, all, of the Fiji Islands. And two curious phrases for 1000 are those of the Banks' Islands, _tar mataqelaqela_, eye blind thousand, _i.e._ many beyond count; and of Malanta, _warehune huto_, opossum's hairs, or _idumie one_, count the sand.[163] The native languages of India, Thibet, and portions of the Indian archipelago furnish us with abundant instances of the formation of secondary numeral scales, which were used only for special purposes, and without in any way interfering with the use of the number words already in use. "Thus the scholars of India, ages ago, selected a set of words for a memoria technica, in order to record dates and numbers. These words they chose for reasons which are still in great measure evident; thus 'moon' or 'earth' expressed 1, there being but one of each; 2 might be called 'eye,' 'wing,' 'arm,' 'jaw,' as going in pairs; for 3 they said 'Rama,' 'fire,' or 'quality,' there being considered to be three Ramas, three kinds of fire, three qualities (guna); for 4 were used 'veda,' 'age,' or 'ocean,' there being four of each recognized; 'season' for 6, because they reckoned six seasons; 'sage' or 'vowel,' for 7, from the seven sages and the seven vowels; and so on with higher numbers, 'sun' for 12, because of his twelve annual denominations, or 'zodiac' from his twelve signs, and 'nail' for 20, a word incidentally bringing in finger notation. As Sanskrit is very rich in synonyms, and as even the numerals themselves might be used, it became very easy to draw up phrases or nonsense verses to record series of numbers by this system of artificial memory."[164]
