Twenty-eight tonsof mangold-wurtzel and Swedish 

 turnips were withdrawn to feed other stock. 



On the 30th January, Mr. Howden took a pair of 

 cattle out of each lot, and fed No. 1 with potatoes and 

 water, No. 2 with Swedish turnips, and No. 3 with 

 mangold-wurtzel. The following shows their relative 

 increase in three months :

When the cattle were sold, the purchasers agreed 

 that the lot fed on Swedish turnips were from fs. to 

 10s. ($1 54 to $2 22) a head better than the other lots. 

 The average advance upon the original va^ue of each 

 was £6 12s. and, the cost of the grains being deducted, 

 there remained £129 ($532 80) in return for the eight 

 acres of produce consumed, or $66 60 for each acre. 



From the above statement it would seem that there 

 is no great difference in the fattening properties of the 

 three kinds of roots ; and that, so far as mea-sure or 

 weight is concerned, it matters little which are em- 

 ployed in feeding. We will note here, for future 

 reference, the product per acre of each kind of roots 

 upon Mr. Howden's ground, adding the product in 

 bushels of fifty-six pounds : 



The potatoes gave 12 tons 4 cwt. equal to 48S bushels.
