If the merits of the common trapped road gullies rise to a neap tidelevel, those of the best sludge box trapped road gullies climb to a Sludge Box Traps. 47 spring-tide high-water mark. For these contrivances ought to in-clude all the good points of the former with the additional advantageof a more or less easily cleaned out gravel or sludge box. They are,however, mostly used in roads where there is a heavy traffic and anincessant scour into the drains; in stable or farm-yards where theincline of the gravel, or pitching of the road, is greater than usual,and at the foot of hills where rock attritions and road washings wouldsoon deprive the trap of its water iPM l^f 117* 110. 119. 120, 121. Figs. 117 and 118 represent two sludge boxed traps, invented aboutthirteen years ago by Mr. E. Jones. Fig. 117 is a small one built inbrickwork, with the drift box in the bottom of the well, and a curveddip plate forming a trap in conjunction with it. The idea is bettercarried out at Fig. 118. I cannot say that, as they stand, they any-where approach near perfection; but the inventor may claim a palmof honour in that he was the first to show a recognition of thenecessity of ventilating the drains. He has provided for this by themeans he has given of unscrewing the bent dip plate which is hingedbelow the water-line, and throwing it back against the opposite wallof trap, as indicated by the dotted lines.
