After the frost in early autumn, the pioneers of the prairie used always to make a holiday in the woods and bring home by wagon-loads the spicy, acid plums which crowded the branches and fairly lit up the thicket with the orange and red color of their puckery, thick skins. In a land where fruit orchards were newly planted, "plum butter" made from the fruit of nature's orchards was gratefully acceptable through the long winters. Even when home-grown sorghum molasses was the only available sweetening, the healthy appetites of prairie boys and girls accepted this "spread" on the bread and butter of noon-day school lunches, as a matter of course.

The Canada plum (_see illustration, page 151_) whose range dips down into the northern tier of states, is so near like the previous species as to be called by Waugh a mere variety. Its leaves are broad and large, and the flowers and fruit larger. A peculiarity of blossoming time is that the petals turn pink before they fall. This tree furnished the settler with a relish for his hard fare, and the horticulturist a hardy stock on which to graft scions of tenderer and better varieties of plums. It is a tree well worth bringing in from the woods to set in a bare fence-corner that will be beautified by the blossoms in spring, and in late summer by the bright orange-colored fruit against the ruddy foliage.
Exotic plums have greatly enriched our horticulture, giving us fruits that vie with the peach in size and lusciousness. In New-England gardens, the damsons, green gages and big red plums are imported varieties of the woolly twigged, thick-leaved European, _P. domestica_, which refused utterly to feel at home on its own roots in the great middle prairies of the country. These European plums have found a congenial home in the mild climate of the West Coast.
Japan has furnished to the Middle West and South a hardy, prolific species, _P. triflora_, generally immune to the black knot, a fungous disease which attacks native plums. Crosses between the Japanese and American native plums promise well. California now ranks first in prune raising as an industry, with France a close second. Prunes are the dried fruit of certain sweet, fleshy kinds of plums. Many cultivated varieties of Japanese plums have enriched the horticulture of our West Coast.
