Note.—Clarks Patent American Hatching-box has layers of trays of brass wire gauze, oneabove the other, enclosed in a box watertight except at the bottom. The water flows downwardshrough these, out at bottom and rising to the top of an outer box, flows over into the next set ofboxes, and so on. This seems likely to remove all sediment.
