    its roughness is not too great, and it is capable of sup- porting heavy weights. In many abattoirs light-coloured fire-clay flags, known as Saargemund or Mettlacher flags, are used, but prac- tical experience shows that on the whole large slabs are preferable, since small flags work loose in course of time. Whatever material is used, no crevices must be left between the flags, but the joints must be filled in with cement. The use of asphalt has been discontinued on account of its slippery surface, and concrete is only employed from motives of econom}^. At the same time, to attempt to save money in regard to the flooring which is exposed to the greatest amount of wear and tear is in the end false economy. A good floor only entails initial expenditure; an inferior one continual outlay for repairs. Above all, artificial tiles should be avoided, as nothing of this kind has stood the test of actual usage. Slaughtering-halls, as a rule, consist of three longi- tudinal divisions, the two next the walls being used for slaughtering, the centre being the gangway for traffic. The slope of the flooring is so arranged that the gutters run next to the walls, and the highest level is in the middle of the centre gangway. This, accordingly, always remains dry. The gutters are placed about 1 foot from the walls, must be of the requisite depth, and be provided with close-fitting gullies at every 3 yards or so, these gullies being the entrances to the drains. The gullies must be furnished with sand and grease-traps in order to, as far as possible, retain all solid matter in the waste-water. If good gullies are used, much of the work done by the sewage clarifying process will be saved. The walls in slaughter-halls are always faced with some material which can be washed. In simply-built abattoirs this facing is of smooth cement, or of a coating
