the town reaches ; and their lower extremities should deliver 

 their contents into a pond, for evaporation, at least a mile 

 from the town. In many situations, instead of evaporating 

 the water in the pond, it might be employed, as it comes from 

 the town, to irrigate adjoining grass lands, or pumped up into 

 water-carts, to be used, in various ways, as liquid manure. In 

 some cases, it might be worth while to erect a small steam- 

 engine and scoop-wheel, like those in the fenny districts, for 

 the purpose of raising the comparatively thinner waters of the 

 sewer to an elevated channel, which channel might convey 

 them to a distance, for the purpose of irrigation. By having 

 two ponds for the deposit, the dense mud of the one pond 

 would be drying, while the other pond was filling and the 

 mud being deposited, as in the case of the ponds near Paris 

 employed in evaporating the material which forms the pou- 

 drette. Were a sewer of the description alluded to carried 

 down the London and Southwark sides of the Thames, at a 

 short distance from its banks, going on a level round the 

 docks, and under the canals, &c, the quantity of most valuable 

 manure that might be deposited on the meadows of Essex, 

 and the shorelands of Kent, almost exceeds calculation. The 

 water of the Thames, being thus left pure, might be pumped 

 up by steam-engines, for the supply of the metropolis. This 

 is an arrangement that must sooner or later be adopted, even 

 in London, and in all old towns ; and it ought to be one of 

 the first objects of attention, in forming new congregations of 

 houses, in every part of the world. 



A second nuisance in Scotch towns arises from the absence 

 of certain conveniences to which we alluded in our preceding 

 article (p. 265.), as being generally wanting in cottages. It 

 is difficult for a stranger to the suburbs of the towns of Scot- 

 land to imagine the state in which he will find the banks of 

 the Nith, within watermark, at Dumfries ; those of the Clyde, 

 at Greenock ; and the seashore, at Ayr. The latter town 

 has just completed a very handsome spire to the town-hall 

 from the design of an architect of great taste, Mr. Hamil- 

 ton of Edinburgh ; and the inhabitants are now occupied 

 in rebuilding Wallace Tower, and placing in it a gigantic 

 statue of Wallace, by the celebrated sculptor Thorn. Surely, 

 therefore, they might spare funds for public water-closets, 

 so much wanted, of which we here suggest two forms (Jigs. 

 64. and 65. and Jigs. 66, 67, and 68.). The former would 

 be a good substitute for the hovel on the quay at Greenock. 

 The contents of the tanks of these buildings might be drawn 

 off by one of Shalder's pumps, placed at some distance from 

 them, and connected by a drain. At Ayr, these contents
