The temptation for mining highly valuable gems should be controlled since such materials were rarely obtained in large quantities in one place, and the buyers were few and rarely available (7.12.13-16, 25 & 31). We may recall Pliny’s comment (31.39) in this context that the Salt Range supplied more revenue to the king than gold and pearls. - [Previous: v2.c41.s3.1](https://indike.org/pramana/ins.science.biswas-1996.v2.c41.s3.1) - [Next: v2.c41.s3.3](https://indike.org/pramana/ins.science.biswas-1996.v2.c41.s3.3) - [Up: v2.c41.s3](https://indike.org/pramana/ins.science.biswas-1996.v2.c41.s3) ## Cites (1) - [Kauṭilīya Arthaśāstra](https://indike.org/pramana/in.niti.artha.kautilya.7.12.13) — Kauṭilya, Sanskrit --- Source: [https://indike.org/pramana/ins.science.biswas-1996.v2.c41.s3.2](https://indike.org/pramana/ins.science.biswas-1996.v2.c41.s3.2) · Pramāṇa
