CLARY. (Salvia sclarca). Its leaves 

 are sometimes used in soups and medi- 

 cated wines. A very small number of 

 plants are sufficient for a family. Sow 

 early in April, or a month earlier, in any 

 light-soiled border. Thin the plants to 

 two feet apart. The sowing must be 

 annual. Seed may be saved by allowing 

 some plants to run up the next spring ; 

 they ripen their seed in September.

CLAY is a constituent of all fertile 

 soils, though in these it rarely exceeds 

 one-sixteenth part, and generally bears 

 a much smaller relative proportion to 

 the other constituents. In its pure state 

 it is known as alumina. It is the best 

 of all additions to light, unretentivc soils, 

 for it retains moisture much more power- 

 fully than any other earth. M. Schubler 

 found, that when silicious sand lost 

 eighty-eight parts of moisture, and chalky 

 sand seventy-six, stiff clay in the same 

 time lost only thirty-five parts. 



Clay soils are the worst that can be 

 for gardens, for there is scarcely one of 

 the crops there cultivated that is not 

 injured by stagnant water, which can 

 scarcely be prevented in clay soils at 

 some seasons ; and in wet weather clayey 

 soils cannot be worked, whereas the 

 gardener must be inserting or attending 

 to his crops every day. 



For the improvement of clay lands, 

 by rendering their staple less retentive, 

 burning some of their own soil is an 

 efficient application. One hundred tons 

 per acre for this purpose are not too 

 many ; for a dressing as a manure, thirty 

 tons are a good quantity. See Paring. 



CLAYING is adding clay to a soil to 

 render it more retentive. 



CLAYTO'NIA. (Named after John Clay- 

 ton, who collected plants in America. 

 !<fat. ord., Purslanes [Portulaceae]. Linn., 

 -Pentandria, \-monoyynia). C. pcrfoii- 

 ita, a gay little annual, is used as a sub- 

 stitute for purslane in North America. 

 Annuals in border of sandy loam, or 

 landy peat, in March and April ; tuber- 

 tus species by offsets in spring or autumn, 

 and seeds in spring ; herbaceous species 

 " y division of the roots ; vegetable 

 lould and peaty soil.
