vigorous is the succeeding crop, as is pretty nearly the case 

 in digging up a crop of Horseraddish. No other culture is 

 given than removing the crop thus spontaneously produced 

 every third year. The juice is pressed from the roots much 

 in the same way as oil is from olives they are first washed 

 perfectly clean, then crushed in an olive mill, then boiled 

 four or five hours, pressed in the olive press, and the juice 

 slowly boiled in an iron vessel. (Bull. Unit).} 



RHUBARB. 



The different species of this plant flourish best in a light, 

 deep soil, more dry than moist, and an exposition to the 

 morning sun. The seeds should be sown as soon as col- 

 lected, and the plants may also be increased, by dividing the 

 roots in the spring. 



TARTS. 



There are several species used for the table the Undu- 

 latum, the Hybridum, and the Rhaponticum the first and 

 second ones mentioned are the most cultivated at London 

 for that purpose. In France, the Rheum compactum is 

 more generally cultivated than any other. 



MEDICINAL. 



It has, for a long period, been considered, that the Rheu 

 palmatum was the rhubarb used for medicinal purposes ; 

 but it has now been proved and decided, by the best autho- 

 rity, that it is a species totally distinct, the Rheum australe, 

 which is used for that purpose. 



ASPARAGUS. 



This plant, which is cultivated very extensively for the 

 markets, requires that the soil be made very rich and light, 

 and that it be made mellow to the depth of 18 or 20 inches. 

 The preferable mode of planting is in long narrow beds of 

 about five feet wide, and the plants should be placed one 

 foot apart each way in the beds. 



DYER'S MADDER. 



This plant, of so much importance in manufactures, and 

 of which we have annually to import large quantities from 

 Holland, will succeed in this country as well as in any part 

 of Europe. It will thrive in any soil except a sand, and 

 would amply remunerate those who would undertake its 

 cultivation on a large scale, as the daily increase of our ma- 

 nufactories will cause an enlarged demand for this indispen- 

 sable article.
