 tlie disease has not penetrated too deep-

 moving be shortened; a thorough system 

 of draining being adopted, either by

 Gardening. 



CANNA. Thirty-eight species and 

 some varieties. Stove herbaceous per- 

 ennials. Seed or division. Ilich light 

 soil. 



C. iridijiora is the most splendid; a 

 writer in the Gardener's Chronicle says, 

 that " so far from requiring stove heat, 

 othc'r part of this work, or'by having the few plants cultivated in a green-house 

 pot used one-fourth filled with pebbles, are more hardy. It only requires pro- 

 and excessive damp during the winter tection from frost, and the border of the 



conservatory is its proper place, where 

 it continues growing, with the thermo- 

 meter varying between 35'^ and 45'^." 



CANTERBURY BELL. Campanula 

 medium. 



CANTHIUM dubium. Green-house 



evergreen shrub. Cuttings. Rich soil. 



CAPE JASMINE. Gardenia fiorida. 



CAPE PHILLYREA. Cassine capen- 



CAPER TREE. Capparis. 



CAPPARIS. Capers. Twenty-nine 

 species. Chiefly stove evergreen shrubs. 

 Cuttings. Loam and peat. 



CAPRIFOLIUM. Goat Leaf. Seven- 



being prevented by proper shelter. 



Parsley grown in a poor soil is also 

 liable to canker in the winter. Mr. 

 Barnes says, he never found any appli- 

 cation which eradicated this disease so 

 etfectually as a mixture in equal parts of 

 soot and slaked lime, sown over the 

 plants. The cure is complete in a few 

 davs, the vigour of the plants restored 

 indicating, that this species of ulcer- 

 ation, like that which is found in the 

 dwellings of the poor, arises from de- 

 ficient nourishment. 



The tubers of the potato also are 

 liable to the speck, black spot, or dry 



gancrene, a disease which I once teen species and some varieties. Chiefly 



thought was occasioned by the calcare 

 ous earth, lime, or chalk contained by 

 the soil, but more lengthened observa- 

 tion has convinced me of my error; and 

 having observed it in all soils, and in 

 seasons characterized by opposite ex- 

 tremes of wetness and dryness, I am 

 induced to consider that the disease 

 arises from some detect in the sets em- 

 ployed, or to potatoes being grown too 



hardy deciduous, or evergreen twming 

 or climbing plants. Cuttings. Common 

 soil. 



CAPSICUM. Twenty-four species 

 and some varieties. Stove evergreen 

 shrubs, or hardy and stove annuals. 

 Seeds. Rich open soil. 



The following are the kitchen garden 

 species and varieties. 



Capsicum Annuum. — Capsicum or

 certain, from my own experience, that 

 in ground tired of potatoes, the disease 

 invariably, and most extensively, ap- i 

 pears. This suggests that it is occa- j 

 sioned by a deficiency of some con- 

 stituent in the soil, a suggestion con- 

 firmed by the fact, that in the fields of.

1. Long-podded.
