The offence of gambling in various forms occupied the attention of the police to a greater degree than before, and the prevalence of rain-gambling led to a test prosecution in the magisterial courts. This form of wagering used to take place during the monsoon at Paidhoni, where a house would be rented at a high price for the four months of the rains by a group of Indian capitalists. There were two forms of _Barsat ka satta_ or rain-gambling, known familiarly as _Calcutta mori_ and _Lakdi satta_. In the former case wagers were laid as to whether the rain would percolate in a fixed time through a specially prepared box filled with sand, the bankers settling the rates or odds by the appearance and direction of the clouds. In the latter case, winnings or losses depended on whether the rainfall during a fixed period of time was sufficient to fill the gutter of a roof and overflow. The gambling took place usually between 6 a.m. and 12 noon, and again between 6 p.m. and midnight, the rates varying according to the appearance of the sky and the time left before the period open for the booking of bets expired. The practice, which was very popular, was responsible for so much loss that in 1888 two of the principal promoters of rain-gambling were prosecuted by the order of Government. The Chief Presidency Magistrate, Mr. Cooper, who tried the case, decided that rain-gambling was not an offence under the Gambling Act, as then existing, and his decision was upheld on appeal by the High Court. Consequently Colonel Wilson applied for the necessary amendment of the Bombay Gambling Act, and this was in due course effected by the Legislature. Since that date rain-gambling has been unknown in Bombay.
