These are the ordinary tuberous-rooted Artichokes, of which, up to 

 the end of 1 !)()!, we have grown eight crops. We have grown them each 

 year without any special application of dung, but on land previously 

 dunged for the preceding crop, except for the plots which on every section 

 are permanently left without dung. 



The following table shows the uvorago of eight years' crops on the 

 principal plots, ami also the average of the last three years, when increased 

 dressings of nitrate of soda were included :
