and the cuttings taken when the new shoots are of a proper length to 

 make cuttings two to three inches long. 



Calofhamnus. — Tender evergreen shrubs of the "Myrtle Family," 

 natives of West Australia. Flowers bright scarlet. Propagated by cut 

 tings of the young shoots, when they have become somewhat firm, placed 

 ]n sand in a frame. The air should not be kept too moist, as there is 

 danger of the cuttings damping off. 



Calycanthus (Sweet Scented Shrub). — A genus of hardy shrubs, 

 all indigenous to the United States. Eeadily increased by seeds, divl' 

 sions, and cuttings of the subterranean stems and branches. 



Catnellia (Tea Plant, Etc.)— rEvergreen shrubs and trees fi-om China 

 and Japan. One of the species, O. tJieifera, and its varieties, yields the 

 tea of commerce. The single varieties are propagated by seed, layers, 

 and cuttings of the green twigs planted in sand in frames or under bell 

 glasses. Cuttings of the season's growth, taken off in the autucon and 

 planted in frames in a cool gi'eenhouse, will usually become rooted by 

 the following spring ; but green cuttings are usually preferred, as they 

 strike root in a few weeks, if at all. The double varieties are propagated 

 by veneer grafting under glass. The grafted plants should be placed in 

 close frames and frequently watered overhead until the cions have 

 united. 



Capparis (Caper Tree). — An extensive genus of evergreen shrubs, 

 of no especial value except the one species, 0. spinosa, which yields the 

 Caper of commerce. It is a native of Soathem Europe, Western Asia, 

 Egypt and North Africa, and is said to be hardy In the Southern coun- 

 ties of England ; hence, it will probably thrive in the open air in some 

 of our Southern States. Propagated by cuttings of the ripe wood in 

 sand, under glass. 



Caragana (Siberian Pea Tree). — All small, hardy, deciduous shrubs, 

 with one exception. The C arborescens of Siberia grows to a height of 

 fifteen to twenty-nve feet in its native country, but ten feet would be 

 considered an extra strong growth in this country. Propagated by 

 seed, layers, cuttings of the roots, and by grafting the low growing 

 species and varieties on the seedling stocks of the C. arborescens. If the 

 seeds are kept dry over winter, they wiU need to be slightly scalded or 

 steeped in tepid water for a few days before sowing in spiing. 



Carpinus (Hornbeam). — A genus of hardy, deciduous trees, mostly 

 of small size, but with very tough and hard wood. The species are 

 propagated by seeds, which are hard and nut-like, and germinate very 

 ii-regularly. Some wiU grow the following spring after sowing, others 

 remaining dormant until the second year. Owing to this uncertainty as 

 to the time of germination, it is always best to sow the seed in the fall 

 as soon as ripe, and in a position where the bed can be freely watered 

 during the following summer, even if but a few plants should appear, 

 gut if jjone are seen by the time warm weather sets in, the entire surface
