These two tables show^ at once the great difference between 

 swedes and yellow turnips. The yield per acre of the latter is 

 in this case half as much again as that of the former, but the 

 character of the crop is very different. Swedes contain fully 10 

 per cent, of solid matter; while yellow turnips do not contain on 

 an average so much as 8 per cent. In consequence of this great 

 difference in composition, the total amount of dry matter per 

 acre produced by the larger crop of yellows is only one-tenth 

 more than tliat produced by the swedes. In the root crop two 

 years ago the difference in composition between the swedes and 

 yellows was not so great, but the means of determining tliat 

 point were not so perfect, and differences in tlie amount of water 

 contained in the tunii[) may naturally be expected to be found 

 according as seasons vary. 



It is right to notice here the method now used, for the relia- 

 bility of the results entirely depends upon that. Owing to the
