The relative and proportionate quantities of coprolite, phosphorite, or ground hones, will vary with the amount of moisture contained in the sludge, but the relative proportions of coprolite, phosphorite, or bones, and of acid should he based on the laws which govern or rule the admixture of sulphuric 5 acid and hones, or other form of insoluble tribasic phosphate with the view of converting the same into a soluble biphosphate in the manner well understood by artificial manure makers. By this means the coprolite or insoluble phosphate is transformed into a soluble or partially soluble phosphate at the same time that the moisture is absorbed from 1C the sludge or sewage deposit, from the fact that the moisture enters into combination with the sulphate of lime, formed as water of crystallization or combination, in which form it becomes latent. By this means not only will the sludge or deposit be rapidly and quickly reduced to a dried state, but will also be materially enriched and rendered valuable as a 1 manure.
