George London and Henry Wise have abridged and edited La Quintinie’s work in order to help gentlemen who have planted fruit trees, but have been disappointed in both the fruit and the trees, because they have neglected the proper techniques. The editors announce in their advertisement for this work that “out of a true regard to the publick, in respect of Gard’ning, we communicate to the World these our Observations, which tho’ few, we hope may be of use. In the first place we think fit to remark that we have gone through the Works of our learned Author with all the exactness we possibly could, abstracting out of each Title, or general Head, all that is useful; and have reduc’d into a proper method, that in which the Original is so prolix and interwoven, that the Reader was rather tir’d than inform’d.” London and Wise go on to note that they have even added some information when La Quintinie had neglected a particular fruit. This work describes fruit and vegetable gardening, showing pruning techniques on nine folded leaves of plates. Various varieties of each fruit and their relative merits are fully discussed. The work also contains a complete listing of the contents of each chapter.

Subjects: Fruit culture; Vegetable gardening.

Don't translate it.It's his name.

Né en 1624 en Charente, Jean-Baptiste La Quintinie, après des études de droit, est reçu à Paris comme avocat à la Cour du Parlement, et maître des requêtes de la Reine. Jean Tambonneau, président de la Cour des Comptes, le remarque, et lui confie l'éducation de son fils Michel. La Quintinie part alors pour un voyage en Italie, dont les jardins servent de référence en France à cette époque encore, afin de familiariser son élève avec les arts. Sa passion pour les jardins se révèle alors, et il décide de se consacrer à cet art du jardinage et de la culture.

Jean Baptiste de la Quintinie (1626 - 1688) designed the royal vegetable garden at Versailles in 1678 for Louis XIV - he also designed gardens for other members of Louis XIV's court, such as Colbert.
