alone? Where, for instance, does its northern limit cross the Adriatic? I learn, that the olive tree resists cold to eight degrees of Reaumur below the freezing-point, which corresponds to fourteen above zero of Fahrenheit: and that the orange resists to four degrees below freezing of Reaumur, which is twenty-three degrees above zero of Fahrenheit. May 19. _Castelnaudari. St. Feriol. Escamaze. Lampy_. Some sheep and cattle; no enclosures. St. Feriol, Escamaze, and Lampy are in the montagnes noires. The country almost entirely waste. Some of it in shrubbery. The _voute d’Escamaze_ is of one hundred and thirty-five yards. Round about Castelnaudari the country is hilly, as it has been constantly from Beziers; it is very rich. Where it is plain, or nearly plain, the soil is black: in general, however, it is hilly and reddish, and in corn. They cultivate a great deal of Indian corn here, which they call millet; it is planted, but not yet up. May 20. _Castelnaudari. Naurouze. Villefranche. Baziege_. At Naurouze is the highest ground which the canal had to pass between the two seas. It became necessary, then, to find water still higher to bring it here. The river Fresquel heading by its two principal branches in the _montagnes noires_, a considerable distance off to the eastward, the springs of the most western one were brought together, and conducted to Naurouze, where its waters are divided, part furnishing the canal towards the ocean, the rest towards the Mediterranean, as far as the _écluse de Fresquel_, where, as has been before noted, the Lampy branch and the Alzau, under the name of the Fresquel, enter.
