The useful arts practised at Nice, are these, gardening and agriculture, with their consequences, the making of wine, oil, and cordage; the rearing of silk-worms, with the subsequent management and manufacture of that production; and the fishing, which I have already described.
Nothing can be more unpromising than the natural soil of this territory, except in a very few narrow bottoms, where there is a stiff clay, which when carefully watered, yields tolerable pasturage. In every other part, the soil consists of a light sand mingled with pebbles, which serves well enough for the culture of vines and olives: but the ground laid out for kitchen herbs, as well as for other fruit must be manured with great care and attention. They have no black cattle to afford such compost as our farmers use in England. The dung of mules and asses, which are their only beasts of burthen, is of very little value for this purpose; and the natural sterility of their ground requires something highly impregnated with nitre and volatile salts. They have recourse therefore to pigeons' dung and ordure, which fully answer their expectations. Every peasant opens, at one corner of his wall, a public house of office for the reception of passengers; and in the town of Nice, every tenement is provided with one of these receptacles, the contents of which are carefully preserved for sale. The peasant comes with his asses and casks to carry it off before day, and pays for it according to its quality, which he examines and investigates, by the taste and flavour. The jakes of a protestant family, who eat gras every day, bears a much higher price than the privy of a good catholic who lives maigre one half of the year. The vaults belonging to the convent of Minims are not worth emptying.
The ground here is not delved with spades as in England, but laboured with a broad, sharp hough, having a short horizontal handle; and the climate is so hot and dry in the summer, that the plants must be watered every morning and evening, especially where it is not shaded by trees. It is surprising to see how the productions of the earth are crouded together. One would imagine they would rob one another of nourishment; and moreover be stifled for want of air; and doubtless this is in some measure the case. Olive and other fruit trees are planted in rows very close to each other. These are connected by vines, and the interstices, between the rows, are filled with corn. The gardens that supply the town with sallad and pot-herbs, lye all on the side of Provence, by the highway. They are surrounded with high stone-walls, or ditches, planted with a kind of cane or large reed, which answers many purposes in this country. The leaves of it afford sustenance to the asses, and the canes not only serve as fences to the inclosures; but are used to prop the vines and pease, and to build habitations for the silkworms: they are formed into arbours, and wore as walking-staves. All these gardens are watered by little rills that come from the mountains, particularly, by the small branches of the two sources which I have described in a former letter, as issuing from the two sides of a mountain, under the names of Fontaine de Muraille, and Fontaine du Temple.
