Excerpt from On the Drainage of Lands, Towns, and Buildings The ﬂat stone drains shown in Figs. 45 and 47 are economical forms of construction in some localities, namely, where the required slabs are cheap and abundant. The shoulders, shown in Fig. 47 as being left in the soil, may be in some cases better substituted by clearing the drain out level, and introducing two slabs of stone, meeting at the bottom, and having a stone wedged in between them at the top, the upper portion being filled in with loose stones. If the ﬂat stones at the sides can be obtained 6 or 8 inches broad, and 15 inches thick, at about 4d. Per ton, an acre of land may be drained with drains 32 inches deep below the crowns of the gathered-up ridges, and laid at distances of r 5 feet, at a cost of about £2 1zs., exclusive of carriage of materials, and the ploughing by which the upper ridges are formed. Constructed as in Fig. 47, if the covering ﬂags can be procured 12 inches wide and 2 inches thick, at the same rate per ton, the acre may be similarly drained for 8s. Or os. Less. For the draining of bogs, the arrangement represented in Fig. 49 is peculiarly applicable, all the materials being on the spot, as the whole drain is refilled with the peat itself, which is well known to resist the action of water with impunity. Provided the cutting of the drains be done in summer, when the material quickly becomes dried, and sufficient time is allowed between the successive opera tions cf cutting and refilling to effect the required con solidation, no better method is yet devised for effecting this kind of work. The liability of the mess in the bed of the drain to subside in detached parts, and with great irregularity, is certain to destroy any arrangement of tiles, pipes, or other artificial materials.

Excerpt from Rudimentary Treatise on the Drainage of Towns and Buildings: Suggestive of Sanatory Regulations Conducive to the Health of an Increasing Population Two volumes of the Rudimentary Series - "The Art of Draining Districts and Lands, and the work now submitted to the reader - relate to the subject of drainage generally, with water supply as an auxiliary or necessary contingent: the removal of surplus waters and refuse on the one hand, and the supply of pure water on the other. The one volume applies to Districts and Lands; the other to Towns and Buildings. It becomes necessary to remark in this (the Third) Edition of the present work, that when the late Mr. Dempsey prepared the First and Second Editions, the whole subject of the Drainage of the Metropolis was in confusion. The most eminent engineers were in conflict as to the best mode of attaining the desired end. The plan eventually adopted, and now (1865) in progress, differs from that which Mr. Dempsey and many other engineers recommended. This, of course, is not conclusive as to the relative merits of the different schemes. Who were right and who were wrong, in these speculations, we shall not know for many years to come; until the Intercepting Main Drainage plan shall have had a fair trial by long-continued working. On this account it seems desirable to leave Mr. Dempsey's calculations and deductions in their original form; because they embody, or rather illustrate, one particular principle of Drainage, which may probably apply to many other large towns, irrespective of its adoption or rejection in the metropolis. By greatly enlarging the Appendix, space has been found for a succinct account of all that has been done in relation to the Main Drainage Scheme since the publication of the Second Edition of this volume, in 1854.
