Hug ban’s Improvements in Treating Sewage. farm refuse, or sweepings, or ashes with either clay, sand, Portland or other cement, sulphated or otherwise, magnesia or magnesium, limestone, salt, or mixtures of two or more of the same, and after having thoroughly incorporated the same I mould or press the mixture thus obtained, and submit the same to a carbonizing and a distillatory process 5 in such a manner as that the resulting condensible products may he obtained and the gaseous products be collected and may be employed for the purposes of illumination, heating, or otherwise. The carbonized product may be retained in a solid form and may be employed in such form as a deodorizing agent or otherwise, or the same 10 having been reduced to powder I employ as an absorbent and deodorizer in the treatment of night soil, urine, and other foecal matters, either alone or in conjunction with the condensed products obtained as before mentioned, and also either with such mixture or sand in conjunction with soluble alkaline silicates, either by mixing the same with the refuse 15 matters to be heated or by filtering such refuse matters through the same. The proportion to be employed will vary with the substances to be heated, but I have found good results may be obtained by employing, for example, in the treatment of night soil or similar refuse the car- 20 bonized product resulting from the carbonization of the before-mentioned mixtures in about the proportion of such material in a divided condition of one-fourth part by weight of the night soil to be operated upon.
