If the blood is dried while perfectly fresh, no offensiveodors are evolved and no deodorizing apparatus would benecessary. If fermentation has once set in, the drying of ready condensability of both the bone-oil and the ammo-nia vapors, and the combustibility of the former, thereis no difficulty in preventing the nuisance from theseworks by the aid of a suitable condensingapparatus connected with the furnacefires. In the reburning of animal charcoalthe odors produced consist mainly of sul-phuretted hydrogen and sulpho- andhydro-carbons, produced by the decom-position of organic matter in the rawsugar.

The floors and buildings should bemade of impervious material, the utmost cleanlinessshould be enforced, and a plentiful supply of water pro-vided. Disposal of Offal.—The offal is collected, cooked ina Wilson tank for about four hours, the water pressedout, and the residual scrap dried in the driers as describedin the preceding section. The odors from the cookingtanks, the driers, and the cooling-boxes should all be car-ried into a condensing apparatus and the material han-dled in the manner described under the head of BloodDrying.
