Mentone is pre-eminently the district of lemons and oranges, grown here for the fruit, and not, as at Grasse, for the flower. Lemons at Mentone are more numerous than oranges. They are not so beautiful, as the fruit has not the golden hue of the orange—it is green or pale sulphur yellow. The fruit of the orange tree will bear 7° Fahr. below freezing point without being seriously affected, but the lemon tree is much more sensitive, and is killed by 8°; it may also perish by over-much moisture in the atmosphere. When a sharp frost sets in, the owners of a plantation of oranges or lemons are in dire alarm, and light fires in the groves, strewing green leaves and grass over the flames to produce smoke, which to a considerable extent prevents radiation, and the temperature falling too low. The lemon tree flowers throughout the year, never resting, flower and fruit being on the tree at the same time. On no other part of the coast do these trees grow as freely as they do at Mentone and Bordighera. But there are no ancient lemon trees, as about once in thirty-five years a bitter winter sets in, and the poor trees perish. The orange tree flowers once only in the year, and bears but a single crop. The fruit ripens in autumn and winter. We, in England, never have the orange in its perfection, as it is picked when green or turning golden and ripens in the cases in which it is packed. But for the orange to be in perfection, luscious and sweet, it should be left on the tree till the end of April, or even into May. It is a beautiful sight, during the winter, to see the orange groves laden with their glorious fruit. The most delicious oranges are those with thin skins, the Mandarin or Tangerine, which ripen earlier than do the Portuguese thick-skinned species. The history of Mentone is not of great interest, and it may be dismissed in a few words. Mentone and rock-perched Roquebrune belonged to the Prince of Monaco. The Grimaldi, John II., having quarrelled with Genoa, appealed for help to the Duke of Savoy, and to buy this help, in 1448 ceded these two places to him for an annual rent of 200 gold florins. However, the Grimaldi got this territory back again, but lost it in 1848, when Mentone and Roquebrune revolted against the fiscal burdens imposed on them by the Prince, and declared themselves independent republics. The President of the Republic of Mentone was Charles Trenca, who died in 1853. Finally, in 1860, both places were united to France, and the claims of the Prince of Monaco were bought off for the sum of four million francs.
