Movement in the \*vāri-yantra\* is fourfold: (a) a downward flow from an overhead tank for which a \*Pāta-yantra\* or waterfall-machine, is to be used; (b) \*Ṣamanādikā\* is for the release of water at a higher level from tanks placed at that level; (c) \*Pātasama-ucchrāya\* is a contrivance using bored columns for letting down water from a height, and then taking it up through columns placed aslant; and (d) the last, \*Ucchrāya\*, in which water from a well or in a canal on the ground is sent up by a device.
