The standard cyclopedia of horticulture; a discussion, for the amateur, and the professional and commercial grower, of the kinds, characteristics and methods of cultivation of the species of plants grown in the regions of the United States and Canada for ornament, for fancy, for fruit and for vegetables; with keys to the natural families and genera, descriptions of the horticultural capabilities of the states and provinces and dependent islands, and sketches of eminent horticulturists . ree of moisture and temperature may be carefullyregulated. In this ripening process, there is not only achange in the sugar-con-tent but the tissues ofthe date are softened,the tanin is precipitatedand the astringency ofthe fruit is therebyrelieved. Vinson foundthat dates may brripened artificially bymeans of chemical re-agents. Artificial ripen-ing by means of heat,moisture, and chemicalstimulation makes pos-sible the production ofcommercial crops at alti-tudes too high and coolto mature many mediumand late varieties. Lossesby rain, insects, andbirds are minimized, andgreater cleanliness se-cured. Last year overhalf the crop from miscel-laneous varieties at theTempe Date Orchard(Arizona) would havebeen lost but for artificialmethods of methods are cheapand practicable. In con-nection with ripeningoperations, the fruit canbe pasteurized at a tem-perature of 65° to 70°C (149°-158°F.) andthen packed undercheese-cloth to secureit from contaminationRecent experiments by. sS^?i®fi?r Fruit clusters of date, asgrown in Arizona. by flies and other show that fumi-gation with carbon bisulfide kills insect eggs, andis preferable to pasteurization with varieties inclinedto be sticky. In 1910, Swingle discovered the pro-cess now in use for ripening Deglet Noor dates by 970 DATE DATURA keeping them in moist atmosphere in closed packing-boxes which are kept warm at night and heated to 80°or 90° F. during the day.
