The preliminary treatment of flax and hemp is mostly carried on in water; and, when piled in heaps or compressed, the wet masses exhibit an objectionable tendency to heat spontaneously, and in some cases to ignite. The danger of piling in heaps is greater in the case of jute, which is sprinkled with oil (soap and olein) in addition to water (in the batching process). The presence of the oil considerably heightens the temperature, which indeed may even attain the point of spontaneous ignition. An important point with these three fibres is to keep all fatty substances at a distance, since even small quantities may lead to spontaneous ignition; and, moreover, the storage temperature should not be over warm. When in a pure and thoroughly dry condition, these three fibres may attain such a degree of desiccation, under the influence of moderate warmth, the radiant heat from a stove or piping, and in summer from the rays of the sun or being stored close under a roof, that pyrophoric carbon is formed and the mass takes fire. In this respect they are more susceptible than wood. The residues left when these fibres are put through the cleaning process are known under the general name of "tow," a ligneous product that finds numerous applications. Tow is dangerous, inasmuch as it will glimmer at even 257 F., and is therefore one of the most easily kindled of fibres. When oiled, it has a greater tendency to take fire spontaneously than the purified fibres, and is specially dangerous, as regards retaining heat, if piled up in somewhat larger heaps than usual. For instance, in one case it …
