The main difficulty at Madras was to keep the peace between the European soldiers of the garrison and the Hindu population. Any European soldier who remained outside the Fort at night time was set publicly in the stocks for a whole day. Any European who attempted to get over the Fort walls, was imprisoned in irons for one entire month, and kept on rice and water. Any soldier who threatened to strike a Hindu was whipped. Any European who took an article out of a shop or bazaar, under pretence of buying it at his own price, was sentenced to pay treble the value to the party aggrieved. [Sidenote: Question of taxation.] Another difficulty was to keep the streets of Black Town clean and wholesome. The Governor and Council summoned the heads of castes, and proposed to levy a small tax on every house. The heads assented to the measure, but offered to carry out the work themselves, and to raise the necessary funds in the same way that they levied contributions from their respective castes for defraying the cost of public festivals. All this, however, was a blind on their part to delude the British Governor and Council. Nothing was done by the heads of castes, no money was collected, and the streets were dirtier than ever. [Sidenote: Contumacy of heads of castes.] Meanwhile Madras was threatened by the Sultan of Golconda, and the Directors in England instructed the Governor and Council at Madras to build a wall round Black Town, and meet the cost by levying a small ground-rent from each householder. In this case no difficulty was anticipated. The Hindus might ignore the importance of sanitation, but they could scarcely refuse to contribute towards the defence of their lives and property, to say nothing of their wives and families. The heads of castes, however, raised strong objections, but found that the Governor was bent on carrying out the orders of the Court of Directors. The heads of castes were told that the rents must be paid, and that those who refused to pay must be prepared to sell their houses and leave the British settlement. At this threat they all promised to pay, but secretly prepared for a general uprising. [Sidenote: Hindu rebellion, 1686.]
