348 THE KOHL-KABI CROP. 



If we compare these results with those already given 

 at page 328, in reference to the composition of the turnip, 

 we see how greatly the kohl-rabi exceeds even the Swede 

 in the proportion of those compounds on which the 

 feeding qualities of the vegetable are supposed to depend. 

 The nitrogen compounds (flesh-formers) are nearly double ; 

 those destitute of nitrogen exist in about the same propor- 

 tion; while the diminished proportion of water it contains 

 would indicate that its keeping properties would be fully 

 equal to the best variety of turnip cultivated. It would 

 be very desirable that before these important points indi- 

 cated by the analysis are received as facts, they should 

 receive confirmation by being practically tested in the 

 feeding shed; so far, however, practice has in most cases 

 been in accordance with theory, which would lead us to 

 expect that in this case the feeding qualities of the kohl- 

 rabi would be found to exceed greatly in value those of 

 our other ordinary root crops.
