In the class of up-and-down play of water, Bhoja expatiates upon the *Dhārāgṛiha*, shower-bower, in the garden; its popularity has already been noted, and Bhoja has already given a description of it in Chapter 18. Its great vogue can also be seen from its different types known by distinct names mentioned by Bhoja: (1) *Pravarshaṇa*, the shower, (2) *Praṇāla*, the pipe, (3) *Jalamagna*, the subaquatic, and (4) the *Nandyāvarta*, in a special design. These are constructed only in palaces for the King's pleasure. (117-18).
