of the side of the trench, the same as the first, and 

 must be planted in the same manner. When this is 

 done, turn over the second trench fifteen inches deep 

 upon the roots so planted, which will level the work : 

 dig up the bottom again as before, and plant the sets in 

 the same manner, and proceed thus till the whole piece 

 is finished. According to this method the rows will be 

 a foot apart, and the sets nine inches distance in the 

 rows. There will be nothing further required from this 

 time than to keep the ground clean, and not to suffer 

 any other crop to be grown upon the ground, as the 

 Horse-radish will soon make its appearance, and occupy 

 all the surface. 



32. HYSSOP. 



Hyssopus officinalis is a neat little evergreen tuft, and 

 most ornamental and fragrant when in flower. It was 

 once in considerable repute as a popular medicine, but 

 is now almost out of use. 



It is propagated by dividing the plant, and planting 

 out the slips in March or April : they will thrive in 

 almost any soil and situation. 



33. JERUSALEM ARTICHOKE. 



Helianthus tuberosus, or Jerusalem Artichoke, is a 

 native of Brazil, and appears to have been introduced 

 in 1617. The tubers are in considerable esteem on the 

 Continent as a substitute for potatoes ; and before that 

 vegetable became plentiful, they were a good deal in use 

 in this country. 



The plant is cultivated in the manner of the Potatoe, 

 by planting the small tubers in February or March, in 

 rows four feet apart, and the sets eighteen inches from 

 each other in the rows. In order to have the roots hand- 

 some, they should be taken up and transplanted into 

 fresh ground every year.
