    epidemic of typhoid fever in Paris, there was none here. The general mortality of Gennevilliers in 1865 was 32 per thousand. In 1876 it was 25, and in 1881, only 22. Measures have been taken to extend the same system over other lands, sufficient for the purification of the entire outflow of the sewers of Paris, save during floods of the Seine, when there is no objection to its direct discharge therein. Correspondingly good results have been reached at Berlin, Breslau, and elsewhere. In fact, the entire adequacy of disposal by application to agricultural lands has been fully and finally demonstrated. Wherever suitable land can be had, this method of disposal meets with no obstacles which experience has not shown us how to surmount, and it encounters no prejudices which acquaintance with its details does not remove. Sewerage engineers are sometimes asked where it is best to dump the sewage, and other expressions are used, suggestive of the disposal of putrid filth by night-soil carts. Sometimes the owners of adjoining lands object to the establishment of a sewage field, in the belief that it will become a nuisance. The fact is, that the dumped matter is fresh and inoffensive, is mainly invisible, save as it clouds the flow, and is a thousand times diluted. If its treatment is properly regulated, it is withdrawn from the diluting water and completely destroyed, in a manner that is imperceptible to our senses, and, in the case of broad irrigation, with the effect of producing a luxuriant vegetation during the growing season.
