On Mangold- Wurz el and Sivedish Turnips for Cattle. 297 



put No. 1 to Swedish turnips, and No. 2 to mangold-wurzel. I 

 ascertained their weight by measurement, and both of them mea- 

 sured the same, viz. 4 ft. 10 in. in length by 6 ft. 5 in. in girth, 

 making them to weigh 6()8 lbs. each. On the 23rd of January, 

 No. 1 had consumed 1624 lbs. of Swedish turnips, and measured 

 4 ft. 10 in. in length by 6 ft. 7 in. in girth, making him to weigh 

 703 lbs., and to have increased in weight 35 lbs., or at the rate of 

 48J lbs. for every ton of Swedish turnips consumed. No. 2 had 

 consumed 1848 lbs. of mangold-wurzel, and measured 4 ft. 10 in. 

 in length by 6 ft. 8 in. in girth, making him to weigh 721 lbs., 

 and to have increased in weight 53 lbs., or at the rate of 65^ lbs. 

 for every ton of mangold-wurzel consumed. 



This difference, however, mio;ht have arisen from No. 2 havinar 

 a greater propensity to feed than No. 1 ; I therefore now put 

 No. 1 to mangold-wurzel, and No. 2 to Swedish, turnips. On 

 the 20th of February, No. 1 had consumed 1884 lbs. of mangold- 

 wurzel, and measured 4 ft. 11 in. in length by 6 ft. 8 in. in girth, 

 making him to weigh 734 lbs., and to have increased in weight 

 this month 31 lbs., or at the rate of 36 j lbs. for every ton of 

 mangold-wurzel consumed. No. 2 had consumed 1880 lbs. of 

 Swedish turnips, and measured 4 ft. 11 in. in length by 6 ft. 8 in. 

 in girth, making him to weigh also 734 lbs., and to have increased 

 in weight during this month 13 lbs., or at the rate of 15| lbs. 

 for every ton of Swedish turnips consumed. I then put both to 

 mangold-wurzel, and divided the food equally between them. 

 On the 19th of March, they had each consumed 1792 lbs. of 

 mangold-wurzel ; No. 1 measured 5 ft. in length by 6 ft. 10 in. 

 in girth, making him to weigh 784 lbs., and to have increased in 

 weight 50 lbs. ; No. 2 measured 5 ft. in length by 6 ft. 9 in. in 

 girth, making him to w'eigh 765 lbs., and to have increased in 

 weight 31 lbs. 



It would appear, therefore, as if the propensity to feed of No. 1 

 was greater than that of No. 2 in the proportion of 50 to 31 ; but, 

 notwithstanding this, in the first month, when No. 1 was upon 

 Swedish turnips, and No. 2 upon mangold-wurzel. No. 2 beat 

 No. 1 in the proportion above stated of 65J; to 48i. It appears 

 as if there could be no great inaccuracy in estimating the relative 

 weight of the animals, as soon after the experiment was concluded 

 I sold No. 1 to a butcher in the country for 24^. Ss., and No. 2 

 at Smithfield for 24/. 



It will be for practical men to decide upon the value of this 

 trial ; what appears to me to be the most conclusive part of it is, 

 that No. 2, who had during the first month, when he was feeding 

 upon mangold-wurzel, increased in girth 3 in., in the next month, 

 when his food was changed to Swedish turnips, did not increase 

 in girth at all, and when in the third month he was feeding again
