The number of permanent pupils in a Mat'h varies from three or four to thirty or forty; besides whom there is also a considerable number of outdoor members. Most of the Mat'hs have a small endowment of land, which they either let at a fixed rental, or cultivate on their own account. Besides this they often receive generous contributions from lay votaries, alms gathered by members who go out to seek them, and the profits arising from traffic covertly carried on.
