In Great Britain, it had grown into an article of faith, that the estimates of engineers for like works, were in no wise to be relied on, and certainly the experience of London justified such incredulity. The whole work was executed by contractors, employing free labor, was paid for by a single city, where slavery is t unknown, and is designed and calculated to supply the wants of any population which that city can sustain. Its copiousness of waters is so great, that two of its fountains daily throw away more

water, than suffices for the supply of other large cities.

Indeed, there is scarcely any feature of the work more imposing and magnificent than the volume of water which its fountains pour out in perennial flow, and the height to which they are projected. There are, to be sure, higher jets in Europe the highest perhaps in the world is that of Cassel, in Westphalia, which, according to modern travellers, rises from a pipe of 12 inches in diameter, to the extraordinary height of two hundred feet but it never plays much more than half an hour !
