 feded. As all three parcels of feed were fown in the 

 fame land, at the fame time, in the fame manner, and 

 managed the fame in every ftage of its growth, it 

 feems clearly to follow, that good clfan found feed 

 in a favourable feafon will produce good found corn; 

 that feed infedted with the fmut, though well wafhed 

 in water, will retain a part of the infe(flion, and pro- 

 duce a fmutty crop; and that fmutty' feed, fown 

 without any wafhing at all, will produce a crop fo 

 fmutty as to be of very little value. 



In like manner, I apprehend, the potatoe, and 

 perhaps every other kind of vegetable, though ori-

 propagated through all fucceeding generations. 



The pured and bed means of guarding againft 

 and preventing this evil, is to follow the advice given 

 by the >jcry intelligent Dodlor, which is to feleft for 

 feed the larged, faired, founded, and bed com- 

 plexioned bulbs; by which means you will mod 

 probably avoid thofc that may be infected with this
