The padres began the cultivation of the pear at the missions. The pioneers of '47 in Oregon and '49 in California started a new era in the cultivation of this and other tree-fruits by introducing named and improved varieties and extending their cultivation along the coast from British Columbia to Lower California. So far, the plantings were fruit gardens, not orchards. The era of commercial fruit-growing began in the year 1869 in which the first fresh fruits were sent east by rail, the shipment amounting to thirty-three tons, mostly pears and apples. This event marks the beginning of a great industry in growing pears on the Pacific slope for the fresh fruit market, and was followed shortly by the introduction of canning and evaporation to use up the surplus product. The special demands of these three more or less distinct industries called for new varieties, and American pomology has been enriched by a score or more varieties of pears from this great pear region. An event which has had a profound influence on pear-growing in the whole country was the introduction of Oriental pears and their hybrids. The mongrel offspring of the Oriental with the European pear were unfortunate in regions where pure-bred European sorts can be grown, but in vast tracts of the United States, as almost the whole of the South and the Middle West, only hybrids of the two species find a congenial environment, and here varieties with Oriental blood became a great asset. The introduction of these pears, also, has greatly stimulated the canning of this fruit in regions where fruit-preserving is an industry. It was hoped that these hybrids could be used successfully as stocks upon which European varieties could be worked, but the stocks have not proved satisfactory, and their use is decreasing.
