" The large stagnating, filthy pond, commonly called the Collect, which now is, or soon will be, the centre of the city, has been looked to by some people, as a fund from whence an adequate supply might be obtained, by means of a steam engine, for all the purposes already spoken of. I cannot undertake to say, that this source would at present be incompetent to all the preceding purposes, for which a supply of water is wanted but ;

if the quantity naturally discharged from this pond, be the whole that is furnished by its

springs, then I might say with propriety, it is infinitely too small for those uses. But admitting, that at present it might be competent, the time will come, and that very shortly, from the growth of the city, when this source will most certainly be very inadequate to the demand. And again, supposing the pond to contain and furnish enough, it is a consideration well deserving attention, whether a pond, into which the filth from many of the streets must, without very great expense and care, be constantly discharged, and to which the contents of vaults, &c., will continually drain, is a desirable source from whence we should like to take water for drinking, cooking, &c., without taking into the account its noxious qualities, medically considered although it may be laid down as a general rule, ;

that the health of a city depends more on its water, than all the rest of the eatables and drinkables put together."
