Le jardinier d'Artois, ou Les élémens de la culture des jardins potagers et fruitiers

This is Bonnelle's manual for gardening, based on the practices of the gardeners and peasants of his native region of Artois, which was a former province of northern France. Bonnelle explains in the preface, that each terroir and climate is specific to its region and there are no existing texts for gardening in Artois. This work is his effort to remedy the problem. He is especially concerned with the cultivation of various foodstuffs, and the sections include garlic, artichoke, asparagus, basil, beets, carrots, watercress, endive, spinach, fennel, green beans, different types of lettuce, celery, mushrooms, cabbage, cucumber, melons, mustard, turnips, onions, parsley, leeks, thyme, and sage as well as apples, peaches, grapes, pears, apricots, plumbs, and various berries. Also included are descriptions of each plant and its cultivation and Bonnells discusses the food's health properties when consumed. For example, the flesh of melons have the virtue to soften, cool, moisten, and temper the heat of the blood and rejoice the heart, while its seeds can cool heated bowels, fortify the stomach and opens the pores.
