 F. The Place, whence the said Channel discharges itself into the river Sor

G. Another Channel of Derivation, conveighing the water of the Black Mount into the Magazin above-mentioned.

H. The Magazine of the water of St. Feriol. ''This work might be reckoned among the Wonders of the World, both for the Contrivance of its admirable Structure, and for the prodigious quantity of Water, it is to contain. For, it will be above twelf-hundred fathoms long, sixhundred large, and twenty two, deep; and is to furnish every minute of an hour, for six moneths of the Year, more than eight Cubic feet of water. This vast Store-house is between'' 2. Mountains, through the middle of which runs the small rivolet Laudot. 'Tis true, Nature hath done something wonderful, in forming a disposition thereto; but 'tis also certain, that Art hath much surpassed her, by the strong Banks or Dams, which are there rais'd to bear up against such a vast quantity of water; as also by the admirable Aque-ducts, that are to have more than 80. fathoms in length, for giving the more liberty and facility to the waters to run out, when there shall he occasion; and lastly, by the great Wall, which is 22. fathoms high, and 600. fathoms long: to say nothing of the incredible quantity of Earth, which 2000. Woemen daily carry to this wall, thereby to strengthen it on both sides.

I. The natural course of the river Audot, which by the means of a Channel conveighs the Water of the said Magazin to the Cape of ofof [sic] Bon Amour, where it Joyns itself with those, that come from Revel to go to the river Sor, to pass together to the Point of Division.

L. The Cape of Bon Amour, so called by reason of the two Channels; where the one, coming from Revel, brings the waters, which went to the Ocean, and the other, which comes from the Magazine, brings those of the Black Mountain, that pass'd towards the Mediterranean.

M. The Port Louys near Revel, newly built, faced with hewn stones of 20. fathom square; where the Lord Bourlemont Arch-bishop of Tholose, and M. de Bezons, Intendant of Justice in Languedoc, accompanied with many of the Nobility, embarqued in'' May 1668. to make an Experiment of this litle Channel, and rowed on to the Stones of Naurouze, with that success, that M. Riquet, having found the advantages, which the neighhouring Towne and Villages night thence receive, besides that of carrying the waters to the Point of Separation, ''did so enlarge the same, that now it carryes great Boats, though it be on the declivity of an Hill: which causeth wonder in all those, that see it.

N. The Channel, that goes from Revel to the Point of Separation.

O. The Royal Channel, which goes from the Garonne into the Lake of Thau or Frontignan. It is to be in its narrowest places 9. or 10 fathoms broad, and at least 9. ''foot deep, according to the places, where it must be more or less digged. You may see in the annexed Mapp a great many rivolets, rivers, and Ponds, which it traverseth, and which in winter are as many''
