Esteemed Friend, 

 Thy address of die 1 1th instant was duly received, in 

 which thou states, that the attention which I have given 

 to the cultivation of the Mangel Wurtzel, will no doubt 

 enable me to furnish a circumstantial account of the pro- 

 cess suitable to be adopted, for the successful manage- 

 ment of that valuable vegetable, and shall feel much obli- 

 ged by my communicating the experience I have acquir- 

 ed on this subject. In conformity with thy request, I 

 will with pleasure communicate any information I am in 

 possession of on the subject ; and although my experi- 

 ence is, no doubt, much more limited than that of many 

 others, in respect to the culture of this highly valuable 

 plant, yet having had, for two seasons past, considerable 

 success in its cultivation, upon a pretty extensive scale, 

 I subjoin the following particulars, which I am in the 

 practice of pursuing in its culture, as well as the manner 

 of gathering in a crop, and preserving it in the winter 

 season. With sentiments of much respect, 



Thine truly.
