very pungent odour, u highly acrid taslc, and strong stimulating pro- 

 perties, which depend upon the presence of a pale yellow volatile oil, 

 which for the most part is dissipated by drying; hence the necessity of 

 keeping it either for domestic or medicinal purposes in sand. Medi- 

 cinally Horse Radish is used as a stimulant and diuretic in dropsical 

 affections, chronic rheumatism, and paralytic affections; it is useful 

 also in some cases of dyspepsia, relaxed throat, and sontie cutaneous 

 diseases. It is found useful also as an external stimulating rubefacient, 

 and infused in milk it is said to form one of the best cosmetics, by its 

 gently stimulating the action of the skin. 



The cultivation of Horse Radish, especially for domestic use, has 

 for some lime had the attention of gardeners. The modes that have 

 been found to answer best are those proposed by Mr. Knight and Mr. 

 Judd ; they agree in the necessity of having the ground deeply 

 trenched, and that of a moist sandy nature is the best, and putting a 

 quantity of manure at the bottom of the trench : then Mr. Knight 

 plants his selected sets on the surface, and as the nutriment is absorbed 

 only by the extremiiies of the small branched lateral and terminal 

 radicles, he calculates on its penetrating the manure below ; but Mr. 

 Judd with the same object in view, having finished trenching, bores 

 holes down to the manure and drops in his sets, and then fills up each 

 hole with wood ashes, rotten tan, or light sand to the surface, through 

 which the plant may easily penetrate. Both plans are good, and 

 answer the purpose very well : the latter is, perhaps, on the whole, 

 preferable, and produces the straightest and stoutest roots.
