literally worth its weight in gold. Indeed, it is always sold by weight - a fact on which the heathen Chinee "with ways that are dark and tricks that are vain" not infrequently relies. Chinamen, who gather large quantities in our Western States to sell to the wholesale druggists for export, sometimes drill holes into the largest roots, pour in melted lead, and plug up the drills so ingeniously that druggists refuse to pay for a Chinaman's diggings until they have handled and weighed each root separately. The DWARF GINSENG, OR GROUND NUT (P. trifolium; Aralia trifolia of Gray) whose little white flowers are clustered in feathery, fluffy balls above the whorl of three compound leaves in April and May, chooses low thickets and moist woods for its habitat - often in the same neighborhood with its larger relative. Yellowish berries follow the fragrant white pompons. One must burrow deep, like the rabbits, to find its round, pungent, sweet, nut-like root, measuring about half an inch across, which few have ever seen. WILD CARROT; QUEEN ANNE'S LACE; BIRD'S-NEST (Daucus Carota) Carrot family Flowers - Small, of unequal sizes (polygamous), white, rarely pinkish gray, 5-parted, in a compound, flat, circular umbel, the central floret often dark crimson; the umbels very concave in fruit. An involucre of narrow, pinnately cut bracts. Stem: 1 to 3 ft. high, with stiff hairs; from a deep, fleshy, conic root. Leaves: Cut into fine, fringy divisions; upper ones smaller and less dissected. Preferred Habitat - Wastelands, fields, roadsides. Flowering Season - June-September. Distribution - Eastern half of United States and Canada. Europe and Asia. A pest to farmers, a joy to the flower lover, and a welcome signal for refreshment to hosts of flies, beetles, bees, and wasps, especially to the paper-nest builders, the sprangly wild carrot lifts its fringy foliage and exquisite lacy, blossoms above the dry soil of three continents. From Europe it has come to spread its delicate wheels over our summer landscape, until whole fields are whitened by them east of the Mississippi. Having proved fittest in the struggle for survival in the fiercer competition of plants in the over-cultivated Old World, it takes its course of empire westward year by year, Finding most favorable conditions for colonizing in our vast, uncultivated area; and the less aggressive, native occupants of our soil are only too readily crowded out. Would that the advocates of unrestricted immigration of foreign peasants studied the parallel examples among floral invaders!
