The farm, therefore, is to that extent a losing affair, and the sanitary results are most unsatisfactory ; but the town, as usual, is glad to have a respite of its legal difficulties, under any pretence and if only for a short time; for assuredly the serious question of fouling the river is as far from being settled as it ever was.](https://iiif.wellcomecollection.org/image/b20411704_0020.jp2/full/800%2C/0/default.jpg)
