Pointing.
All joints to be at least ½″ in depth, and thoroughly cleaned out by watering and rubbing with a brush. Mortar for pointing to be composed of one part of lime and one part of soorki, ground very fine in a mill, or strained through coarse cloth. Flush pointing to be lined off true horizontally and vertically with a string, the lines thus made to be deepened by a rule made for the purpose.
Culverts.
The type of culverts adopted must be dependent on the depth of the drain below the surface of the road. Where arching can be done it is preferable. Where impracticable, the top should be covered with stone slabs. Parapets should be provided with stone copings. All culverts on a road or street should be numbered, and registered in the form given in Appendix G, page [74].
The system of quadrennial repairs to bridges and culverts is an essential towards efficient administration, and when once successfully introduced, is economical.
In masonry buildings a damp-proof course, which may be made with either asphalte, or with a layer of Portland cement 1″ in thickness, laid at the top of the plinth, and just above floor-level, is most desirable in order to prevent damp rising in the walls, if for no other reason than that it prevents damage to the masonry, and to the plastering, or pointing.
CHAPTER V.
Latrines and Urinals.
In dealing with the sanitation of a bazaar, the provision of scientifically designed latrines and urinals is a matter of the greatest importance. There are numerous patterns of these, some very well arranged as regards the necessary requirements for efficient working, but many more not so. The selection of the pattern adopted is frequently a mere matter of chance, and the attention paid to the subject by the Municipal Commissioners a minimum quantity; badly arranged ones are probably just as expensive to construct in the first instance as good ones, which are much more useful.
