therefore treacling on the bads should 

 be carefully avoided. The shoots make 

 their appearance in. May or June, or 

 earlier if the sets were planted in 

 autumn. 



Remove the leaves as they decay in 

 autumn; the ground being also hoed 

 and raked over at the same season, 

 which may be repeated in the following 

 spring. 



In the succeeding autumn they 

 merely require to be hoed as before, 

 and may be taken up as wanted. By 

 having three beds devoted to this root, 

 one will always be lying fallow and im- 

 proving ; of which period advantage 

 should be taken to apply any requisite 

 manure. 



Takiny up. To take them up a 

 trench is dug along the outside row 

 down to the bottom of the roots, which, 

 when the bed is:continued in one place, 

 may be cut off level to the original 

 stool, and the earth from the next row 

 then turned over them to the requisite 

 depth ; and so in rotation to the end 

 of the plantation. By this mode a bed 

 will continue in perfection for five or 

 six years ; after which a fresh plantation 

 is usually necessary, But the best 

 practice is to take the crop up entirely, 

 and to form a plantation annually ; for 

 it not only causes the roots to be finer, 

 but also affords the opportunity of 

 changing the site. If this mode is fol- 

 lowed care must be taken to, raise every 

 lateral root; for almost the smallest 

 will vegetate if left in the ground.

 HOTBED is a bed of earth, or other 



material, usually covered by a glazed 

 frame, and heated artificially, and em- 

 ployed either for forcing certain vege- 

 tables, for raising seedlings, or for 

 striking cuttings. It is heated either 

 by dung, or leaves, or tan in a state of 

 fermentation, or by hot water. 



Hotbed of Stable Duny : Preparation 

 of Dung. We will commence with the 

 dung fresh at the stable door ; the 

 first thing is to throw it into a close 

 body to " sweat." Those amateurs who 

 have plenty, and to spare, will do well 

 to shake it over loosely, and reject a 

 portion of the mere droppings ; for 

 these take the most purifying, and, 

 moreover, engender an over-powerful, 

 and sometimes unmanageable heat, 

 which in unpractised hands is capable 

 of much mischief. The main bulk of 

 the material thus thrown together will, 

 in a week or so, become exceedingly 

 hot, and must then be turned com- 

 pletely inside out ; and, in so doing, 

 every lock or patch which adheres to- 

 gether must be divided. Water will 

 now be requisite, and must be regularly 

 applied as the work proceeds, rendering 

 every portion equally moist. After the 

 mass has lain for about four days.
