92 On the Cultivation of the Horse Radish. 



by placing the foot on the lower extremity, and carefully lifting 

 the root out of the ground as far as may be necessary. This 

 operation is performed two or three times every summer. When 

 the operation is over, replace the roots as before, and cover them 

 with mould. The roots or fibres which are left at the end of the 

 main root and not disturbed (for the operation must be done care- 

 fully) are sufficient to nourish the plant. In the third year the roots 

 have attained their full size. Laying the roots horizontally has 

 the advantage that they are easily taken out of the ground without 

 breaking ; while cutting off the side roots, makes the main root grow 

 strait and thick. It is advisable to plant a bed every year. To 

 keep the ground clear of weeds need not be mentioned. 



I remain, 

 Sir, with the greatest respect, 

 Your most obedient humble servant, 



Jens Peter Petersen.
