As soon as the roots are taken from the soil they 

 require certain care, to which attention is called, this 

 being previous to transportation. This latter opera- 

 tion has been carefully studied, and the account is far 

 more complete than any thing of the same sort, to his 

 knowledge, written up to the present day ; he, having 

 visited the farms and factories where these different 

 devices were working, had the advantage of judging of 

 the results to be expected. Each plan gives satisfac- 

 tion in different ways, and for this reason they are all 

 of interest, and every possible circumstance that can 

 present itself is here given, which permits of the carry- 

 ing of the beet from one place to another. 



As to the silos, the author has made a considerable

 produced by the excessive cold, fermentation, etc., 

 would be a direct cause of failure in many cases, which 

 would be attributed to poor beets, and which in reality 

 was in consequence of neglect. The situation of these 

 silos is also important. "With this the various methods 

 proposed and adopted for the conservation of the root, 

 such as desiccation, or uniting the juice with lime, to 

 render all alteration impossible, have been given. 



The study of the ravages of the enemies of the beet 

 has been done with equal care. Similar cases may have 

 to be contended with in America. Efforts have been
