Ohs. This favorite vegetable is pi etty extensively cultivated here, and succeeds we!!,— though I think 

 the roots, raised here, are r;it!ier inferior in qualily. to thos^^ raised in the sandy soil of New-Jer.sey. It 

 is propagated by cuttings of the roots*; which are planted the beginning of May, It never flowers, m this

Ohs. This plant is occasionally cultivated, on a .small scale, by some tobacco-chewing farmers. It 

 possesses powerful medical properties: but, unfortunately, it may be remar' ed. .Timost without a fi»ure. 

 in relation to many of our people, that what r)Ui;ht (o be " th.'ir extreme medicine, is become their daily 

 bread"! The seed is sown about the middle of April, in beds; and the young plants subsequently remo- 

 ved into distinct hills.

ilaft. Gardens, and fields. Perennial-' 2 to 3 feet high: dosvers bluish white. i".^ai. Soutli America. 



Obs. This most important plant is cultiv.ited e\tpn.'-.ivclv: as it well deserves to be. It is usually propa- 

 gated by cuttings of the tubers; but they are liable to degenerate, by long con*in ird culture^in the 'ome 

 eoil— and ought then to be replaced by seedlinirs, cnrt^fulty .solpcted. The roots are planted in all the 

 months of April, May and June My friend, tho late Dr. Baldwin informed me he saw this idant grow- 

 ing native, near Monte video, on the river La Plata, in the year 1813.
