stand the diminished wasting power. Unless, then, the depositions which are to be 
removed are of less tenacity than the banks, it is quite obvious that the current will, 
by it inevitable effect on the banks, destroy itself, so that in time it shall be no longer 
able to effect its purpose. The banks then become stable, i. e. comparatively, but 
with them the sands and shallows are also made permanent, whatever machinery 
be used to disturb them. When, therefore, it is considered what the r ature of the 
soil is through which these rivers take their course at their afflux from the Ganges, 
it does not seem exaggerating the difficulties of the problem to say, that in a natural 
channel it is not practicable to keep these rivers open. 
Major Schalch having shown, as well the inutility as dang’er of attempting the 
cure of the evil in that direction, next turns to the object of his Memoii, which is to 
propose a canal of communication between the IIugli and the great river, which 
shall not only be free of these objections, 14 hut be likely to repay, in a short time, the 
expense of excavation, and ultimately become a source of considerable i even ue to

canal he proposes 'to carry across the several rivers which cover with their anas- 
tomosing branches the tract called the Sunderbunds, but on such a l.neas to he with- 
in the influence of the tides : the advantages of giving this direction to the canal he 
considers will be the following— The surface of the ground being so little elevated above 
the level of high water, the expense of excavation will be trifling. For the same reason, 
no locks will be required, as the numerous inlets from the sea will always afford a 
sufficient supply of water. Nor will the banks be liable to change, as the alternate 
flux and reflux of the tide seems favourable to the durability of such channels. 
To the present route by the Sunderbunds, which proceeds by lolley s Nullah 
there are many objections besides its circuitous direction. Thus from the great

when it is most required, it is literally chocked with boats to a distance of 3 01 4 
miles beyond Garriahath ; and many of the boats, deeming their farther progress 
hopeless/ are in the practice of landing their cargoes to be conveyed to [Calcutta . by
