Naturally architectural erections add to the excellence of the fountain-park and parts of the structure are themselves used for the different water-works. - [Previous: c2.197](https://indike.org/pramana/ins.science.raghavan-1952.c2.197) - [Next: c2.199](https://indike.org/pramana/ins.science.raghavan-1952.c2.199) - [Up: c2](https://indike.org/pramana/ins.science.raghavan-1952.c2) --- Source: [https://indike.org/pramana/ins.science.raghavan-1952.c2.198](https://indike.org/pramana/ins.science.raghavan-1952.c2.198) · Pramāṇa
