854 KALMIA 



decorative, contrasting well with tbe red and yellowish 

 branches. The species is also easily forced and makes 

 a very handsome pot-plant. The other species are 

 pretty border plants for evergreen shrubberies. The 

 Kalmias thrive well in a sandy, peaty or loamy soil, 

 but dislike clay and limestone. They grow almost as 

 well in swamps as in drier locations and prefer partly 

 shaded situations, but thrive also well in sunny places, 

 provided there be sufficient moisture. They require gen- 

 erally almost the same treatment as the hardy Rhodo- 

 dendron, but are less particular about soil and position. 

 Transplanting, if carefully done either early in fall or in 

 spring, is not difficult ; a mulching the first season after 

 planting will be of much advantage to keep the roots 

 from drying in summer and from frost in winter. Prop, 

 usually by seeds sown in sandy, peaty soil in pans or 

 boxes in early spring and kept in a cool frame or green- 

 house. The seedlings should be pricked off as soon as 

 they can be handled, and after they are again established 

 gradually hardened off and the following year trans- 

 planted in frames or beds outdoors. Vars. of K. lati- 

 folia are usually increased by side-grafting on seedlings 

 in the greenhouse or by layers, since it grows less 

 readily from cuttings, while the other species may be 

 prop, by cuttings of half-ripened wood under glass. 

 Six species in N. Amer. and Cuba, allied to Rhododen- 

 dron : fls. in terminal or lateral corymbs or umbels, 

 rarely solitary; calyx 5-parted; corolla saucer-shaped 

 or broadly companulate, 5-lobed; stamens 10, with slen- 

 der filaments, the anthers held back in little pouches of 

 the corolla, springing up suddenly and discharging the 

 pollen if touched : ovary 5-celled, superior ; capsule

globular, parting into 5 valves, with numerous minute 

 seeds. The Ivs. of the Kalmias are said to be poisonous 

 to animals, especially those of JC. avffusiifolia^ The 

 flower of Kalmia is one of those proposed as a national 

 flower emblem, especially on account of the exquisite 

 symmetrical beauty of the single flower. It is a purely 

 American genus, hut unfortunately it is popularly known 

 only in the eastern states.

KANSAS, HORTICULTURE IN. Fig. 1206. In 18.^.4, 

 when Congress passed a law opening this territory for 

 settlement, it was considered as part of the great 

 American desert, and it was almost universally thought 

 to be fit only for grazing purposes. As to fruit-grow- 

 ing, such a possibility was not considered. This im- 

 pression did much to retard tree-planting. Another 

 great drawback was the fact that every settler planting 

 fruit trees must have the favorite varieties of his former 

 home grown. This resulted in the planting of over 

 2.000 kinds of apples alone. Few of these could be made 

 to succeed, and, in time, so many failed that the impres- 

 sion was deepened that Kansas could not grow fruit. 

 But amid these losses occasionally a man would succeed 

 with some variety, and his success was heralded over 

 the state until eventually the worthless kinds were 

 weeded out and the road to success was perceived. 

 Eventually the people could plant trees with some as-
