On the Cultivation of Celeriac, $c. 421 



In Denmark and the northern parts of Germany, the roots 

 are generally taken out of the ground at the end of October, 

 and preserved for winter use in sand in a dry house, or in a 

 pit made in the open ground, secured from the frost, by 

 which they are liable to be injured in severe winters, if not 

 protected. 



I have the honour to be, 

 Sir, 



your most obedient humble Servant, 



Jens Peter Petersen. 



Mr. Lee's Nursery, Hammersmith, 

 February 23, 1820',
