Perhaps one, at least, of these lesser centers of pear-growing somewhat to the south of the pear regions in which there are now commercial plantations should receive notice. In 1794, William Coxe,[13] Burlington, New Jersey, began planting experimental orchards. Coxe was acquainted with the leading pomologists of Europe and his own country, and collected the best varieties of tree-fruits to be found in the United States, England, and France. In 1817, he published his _View of the Cultivation of Fruit Trees, and the Management of Orchards and Cider, etc._, the first American book on pomology. This pioneer pomologist described 65 varieties of pears, most of which he had grown at one time or another on his own place, and names 21 other sorts that were grown in his and neighboring states. Coxe seems to have been the first nurseryman to import new varieties from the Old World. To Coxe, more than to any other one man, the regions adjacent to the Delaware are indebted for the early development of fruit-growing both for pleasure and profit, and the whole country is indebted to him for the introduction of many fine fruits. A new phase in the history of the pear began soon after the Revolutionary war. Until this time, and until well into the next century, tree-fruits were nearly all seedlings. The pears of the country until as late as 1830 were for most part seedlings, the fruits varying greatly in size, shape, color, and flavor. According to the accounts of the times, the product was so hard of flesh and so astringent in flavor as to be fit only for cooking and perry. Indeed, the great object in growing apples, pears, and peaches was the making of cider, perry, and peach-brandy. Good eating pears were few indeed. But beginning in a small way with Coxe in New Jersey, as noted, a little later with William Kenrick, Newton, Massachusetts, and still later with Robert Manning, Salem, Massachusetts, the importation of European varieties of fruits became an important part of the nursery business. The importation of pears became an obsession with Manning, his nursery alone importing several hundred varieties. Manning's work must have a more extended notice.
