GYPSUM, or PLASTEB OF PAEIS, is a sul- 

 phate of Kme, composed ot Sulphuric 

 acid, 43 ; lime, 33 ; water, 24. It has been 

 employed advantageously as a manure to 

 clover, the turnip, and potato, at the rate 

 of 3 cwt. per acre. Potato sets are fre- 

 quently rolled in it when pulverized. It 

 has been recommended to be sprinkled 

 in stables, and to be mixed with dung- 

 hills, "to fix the ammonia," as it is 

 popularly termed. All tbe ammonia lost 

 in fumes from a dung-hill might be more 

 readily and as cheaply restored to it by 

 mixing with it, when dug into the soil, 

 a little of the ammoniacal liquor from 

 the gas-works. 



H. 



HABENA'EIA. (From habena, a rein; 

 referring to the long, strap-shaped spur. 

 Nat. ord., Orchids [Orchidacese]. Linn., 

 20-Gynandria 1-Monandria. Allied to 

 Gymnademia.) 



Some will grow in peaty soil in the open border, 

 if kept a little protected, and somewhat dry in 

 winter ; others are stove orchids, requiring peat 

 and loam, and treatment similar to a Bletia. Di- 

 visions of the root. Summer temp., 60 to 80; 

 rest period, in winter, 50; and when starting into 

 flower, 70.

HABIT is the appearance or mode of 

 growth. Thus a Verbena may be of 

 straggling or shrubby, compact habit. 

 This habit is much influenced by soil and 

 cultivation. Thus Bu'xits sempervi'rens 

 in a poor soil is dwarfish, but in a rich 

 soil becomes tree-like. The term habit 

 is applied to the power a plant possesses 

 of vegetating earlier or later, when once 

 accustomed to do so. Thus, a vine once 

 forced to break early will retain the habit 

 of doing so the following year, though, 

 not forced. 



HABITAT. The native place of a plant. 



HABBA'NTHUS. (From habros, delicate, 

 and anthos, a flower. Nat. ord., Amaryllids 

 [Amaryllidacese]. Linn., 6-Hexandria 1- 

 Monogynla. Allied to Phycella and Ze- 

 phyranthes.) 



The Habranthi are natives of dry, gravelly places, 

 and are half-hardy with us, but retaining their 

 leaves in winter ; if in an open border, they re- 

 quire a glass covering; they flower without the 

 leaves after a period of rest. Offsets and seeds, 

 which are produced often freely, and which should 

 be sown when gathered, or carefully saved until 

 the following spring, and then have the assistance 

 of a hotbed ; sandy loam and a little peat.
