Although everything was thoroughly dried up, it was easy to imagine the
effect of an inundation of the Pedias river, which had formed this delta
of alluvium, precisely as the Nile on a more extensive scale has
produced the Delta of Egypt. There were a few wretched villages upon the
flat, which were necessarily on the poorest scale, as they existed at
the mercy of a sudden inundation. The unhealthiness of this locality
must be extreme during wet weather, as it is only suitable to the
constitutions of frogs and ducks. Upon arrival at higher ground on the
opposite side of the plain I looked back upon the agueish area over
which we had passed, and I had little doubt of the great engineering
necessity that must be the first step to a sanitary reform in this
pestilential neighbourhood.
As the river Pedias is a mere wayward torrent that NEVER flows as a
permanent stream, but only comes down in impulsive rushes from the
mountains during heavy rains, it has no power to cleanse its original
bed, such as would result from a constant and clear current; but, on the
contrary, the heavy floods from the upper country, being the result of a
sudden rainfall, are surcharged with earth washed down from the higher
ground and thickly held in solution. This vast mass of soil, which adds
a corresponding weight to each gallon of water, is carried forward
according to the velocity of the stream, and is ready to deposit upon
the instant that the propelling power shall be withdrawn.
