[Illustration: AXLE, COLLAR, AND BUSH FIG. 20. ] In Municipalities where the quality of work warrants it, it will be found economical to maintain a small workshop where repairs can be done, but this must be properly organized. The following cart Register kept up in Patna City will simplify control of the carts, and ensure proper repairs being done. It commences with an Index, each cart is numbered consecutively, whether it be water, conservancy or refuse cart, and the number permanently marked on it. At the ledger folios referring to any cart appears— 1. The number of cart. 2. Date when made. 3. Maker’s name. 4. Where worked (ward and by whom) and below that ─────────────────┬─────────────────┬─────────────────┬───────────────── Date. │Note of repairs. │ Cost. │ REMARKS. ─────────────────┼─────────────────┼─────────────────┼───────────────── 1902 │ New axle │ Rs. 9–2–0 │ 12 11 │ │ │ ─────────────────┴─────────────────┴─────────────────┴───────────────── This is of course separate from the Stock Register, and may appear to be a mere detail of organization, but is very useful in administration. For towns and small Municipalities Incineration is by far the safest, and in most cases, the most economical method of getting rid of rubbish. If night-soil be mixed with the rubbish nuisance generally arises. There are various types of incinerators, but for burning town refuse only a very simple one, merely a furnace and chimney, is quite enough, and several of these can be constructed at a very small cost outside a municipality at convenient centres, where the smoke will not cause a nuisance. Many of the existing incinerators have been designed to burn night-soil as well as refuse, as is generally done in military camps and forts on the frontier. [Sidenote: Madras Incinerator.] The Madras type Incinerator is shown in Figs. 21 and 22, page 46. These were designed to suit local conditions by Mr. C. L. Griffith, while Engineer of the Corporation, and cost Rs. 100 for masonry and Rs. 25 for ironwork. There are a considerable number of these at work, distributed throughout the Municipal area, so as to reduce the load for carting to a minimum, a very important factor in a straggling town. [Illustration: HALF SECTION & ELEVATION FIG. 21. PLAN OF AN INCINERATOR ] [Illustration: PLAN FIG. 22. ] The Sealkot Improved Type Incinerator is also a suitable and economical one. A 4′ diameter one is capable of burning about 300 cub. ft. of rubbish daily, and it costs about Rs. 400. _See_ Fig. 23. [Illustration: FIG. 23. ] [Sidenote: Harrington’s Improved Incinerator.]
