Mahommedan burial-grounds should not be allowed near crowded areas, or the sources of water-supply. In most towns these will be found to be overcrowded; new ones should be opened under municipal control, as provided for in sections 254 to 260A, Part VI of the Bengal Municipal Act. An area of half an acre for every 1,000 Mahommedan inhabitants is desirable if land is available, but may be reduced to quarter of an acre where such is very expensive. This allows of the graves being undisturbed for a period of seven years. [Sidenote: Ruined houses.] Where a house has been dismantled, or is in ruins, the owner should be made either to repair it or remove the materials; the remains of walls serve as a cover for the committal of nuisances and the deposit of refuse. [Sidenote: Building Regulations.] Building Regulations should be adopted in all Municipalities. Those framed for Patna City under section 241, Part VI, of the Bengal Municipal Act, are given in Appendix D, page 63. The rule that no building in any street shall be higher than the distance from its base to the opposite side of the street is a very essential one to observe. In the Bombay Improvement Trust the angle of 63½ from the opposite side of any street or lane, regulates the height permissible in any building. APPENDIX A. MODEL RULES AS TO PRIVATE PRIVIES AND URINALS. (GOVERNMENT OF BENGAL.) [_See Act III of 1884, Section 350 (c)._] 1.

[Sidenote: Provisions of access to service privy from street.] 2. (1) No privy shall be placed on any upper floor of a building. 3.

[Sidenote: Models and type-plans.] (2) Every notice served under sub-rule (1) must require that such passage be formed at ground-level, but not less than four feet wide, and be provided with a suitable door, and must inform the said owner that the passage may, at his option, be either open to the sky or covered in.
