Note 5 — Chapter XXXVII · TO CHAMPÂ AND TÂMALIPTÎ. STAY AND LABOURS THERE FOR THREE YEARS. TAKES SHIP TO SINGHALA, OR CEYLON.
James Legge translation
The kingdom is on a large island, extending from east to west fifty yojanas, and from north to south thirty. Left and right from it there are as many as 100 small islands, distant from one another ten, twenty, or even 200 le; but all subject to the large island. Most of them produce pearls and precious stones of various kinds; there is one which produces the pure and brilliant pearl,5—an island which would form a square of about ten le. The king employs men to watch and protect it, and requires three out of every ten such pearls, which the collectors find.
