til the next season, when they are hatch- 

 ed and attack the -roots of the Cabbage 

 plants, and thus bring on the disease. 

 As an evidence of the correctness of this 

 belief, we never fail to find, for example, 

 if we plant alongside of each other, a 

 crop of Cabbage and a crop of Potatoes 

 or Beets, that if the succeeding year we 

 plant the whole with Cabbage, the part 

 only that was planted with Cabbage the 

 year before will be affected by Club Root, 

 and the parts planted with Potatoes or 

 Beets will escape. From our experience 

 that Cabbage planted in soils mixed with 

 oyster shells is exempt from Club Boot, 

 it is evident that the lime in the oyster 

 shells is the agent destructive to the in- 

 sect; therefore, in soils having no oyster 

 shells, we have found, if air-slacked lime 

 is put on at the rate of 150 bushels to the 

 acre after plowing, and well harrowed in, 

 so as to mix it with the soil, that it in 

 most cases will destroy the larv$e which 

 causes Club Root. We have also found, 

 from its containing large quantities of 

 lime, that Bone Dust, used as a fertilizer 

 at the rate of one to two tons per acre, is 

 another almost certain antidote against 

 Club Root. We would advise the use of 

 lime after fall plowing, but the Bone 

 Dust should only be put on before the 

 crop is planted in spring. 



Club-shaped. The same as Clavate, which 

 see. 



Clufriacece. The Gamboge family, a natu- 

 ral order belonging to Thalamifloral Di- 

 cotyledons, usually called GuUifene, 

 which see. 



Clustered. Where numerous similar parts 

 are collected in a close, compact manner, 

 as in the flowers of Cuscufa. 



Clypeate. Having the form of an ancient 

 buckler, the same as Scutate, which see. 



COC 



Coaceri-ate. (lathered together in a round 

 mass; the same as clustered, which see. 



Coadnale, Coadunafe. The same as connate, 

 which see. 



Coagulants. Congealing together. 



Coalifio. The growing of one thing to an- 

 other; as when petals grow together to 

 form a monopetalous corolla. 



Coarctate. Contracted, or drawn close to- 

 gether. 



Coarclure. The neck of a plant. See Col- 

 lum. 



Coated. Where the external parts are hard- 

 er than the internal; or are composed 

 of a distinct layer, as the bark on the 

 trunk, the rind of fruit, etc. 



Cobwebbed. Covered with loose, white, en- 

 tangled, thin hair, resembling the web of 

 a spider, as inSempervivumarachnoideum 

 and other plants. 



Coccidia. A peculiar form of the concepta- 

 cles (which see) in the rose-spored Algae, 

 which consists of globur tubercles with a 

 cellular wall continued from the sub- 

 stance of the frond, whether partly con- 

 fluent with it or free, and not opening in 

 general by a terminal spore, as in Rho- 

 dymenia and Gracilaria. The elongated 

 processes in such Algce as Gigartina mam- 

 millosa are called tubercles. In this 

 species at least there is a pore for the 

 exit of the spores. 



Coccineus. A pure carmine color, slightly 

 tinged with yellow. 



Coccodis. Resembling pills; consisting of 



spheroidal granulations. 

 Coccus. A shell; a carpel, which separates 

 with elasticity from an axis common to 

 itself and others, as in Euphorbia, Rici- 

 nus, etc. 



Cochlear. A term used in describing aesti- 

 vation, (which see,) when one piece, be- 

 ing larger than the others and hollowed
