Seas, by joyning the
Waters of this Rivolet by a Channel (to be kept full all the year long)
with those of St. _Papoul_, and others, which fall into _Fresqueil_
(another small River) that runs into the _Aude_ below _Carcassone_, and go
together to _Narbonne_, scituated upon the _Mediterranean_.

Having given the Proposition, he adds some particulars, to illustrate the
same, before he declares his judgment upon it. For he relateth, that there
is but one way, after the division of the Waters, to pass to the
_Mediterranean_, which is by a Rivolet, called _Fresqueil_, that is
conjoyn'd with the _Aude_: But, to pass to the _Ocean_, there are three;
One, by _Riege_, entring into the _Caronne_ above _Tholouse_; the other, by
_Lers_, passing on the side, and below the same Town; and the third, by
_Sor_, falling into the River _Agoust_ under _Castres_, afterwards into the
_Tarne_, and thence to _Montauban_, and lastly into the _Garonne_. And
that, to compass this design, all these Rivers and Rivolets are first to be
made Navigable unto their _Sluces_; that of _Aude_ and _Fresqueil_ for the
_Mediterranean_, and one of the others, such as shall be chosen, for the
_Ocean_. He addeth, that, as to the several Ways passing to the _Ocean_,
all of them commended as proper and convenient, and the three Countries
concerned therein, speaking every one for their advantage: Those of
_Castres_ and {42} _Montauban_, are for the River _Agoust_; those of
_Tholouse_, for _Riege_; and the rest, for _Lers_.

Now concerning his Opinion upon this Proposition, he thinks, that all that
hath been represented touching this matter, can signifie very little,
seeing that the main thing is wanting, which is the assurance, and certain
and positive mensuration of the height and quantity of the Waters,
necessary to fall into both the Channels of the _Aude_ and _Caronne_: that
there must be plenty of that, to furnish at all times and alwayes the
highest and first _sluces_, since what once issues thence, doth never enter
again into them; and after some Boats are passed, if there should not be a
sufficient supply for those that come after; either to go up, or to go
down, all would stand dry, and Merchants and their commodities would stay
long enough expecting the supply of Rains, to their great detriment. He
concludeth therefore, that no knowing and discreet Person is able, in
matters of this nature, to give a positive answer, without having before
him a large and
