This ll^d. will represent the value of the swedes consumed per 
week, that is 7 X 17 = 119 lbs.

112 lbs. = lOid. 
or a ton is worth 1 7s. 6d. exclusive of the manure. 
Nor^ my Lord, is this estimate unsupported by scientific authority. 
I beg to refer to an experiment detailed by Professor Playfair, 
Agricultural Gazette, p. 59, 1844 — where it is shown that under 
certain conditions 100 lbs. of swedes gave 3 lbs. of live weight. 
Also to the ver\' interesting experiments of Mr. Curwen, in his 
' Agricultural Hints/ showing that Mason's Leicesters, fed on 
turnips, would make the crop worth 30/. per acre, meat being at 
that time Q>d. per lb. in the year 1808. 
I confidently hope that you will excuse the length of this letter, 
as I am most anxious to secure the attention of the great agri- 
culturists to this question — " What is the value of the swede 
crop under given conditions ? ''

To determine the value of the dung resulting from the consumption of 
a ton of swedes by sheep under cover, eating a pint of oats to every 
17 lbs. weight of turnips ;— 
The ash contained in one ton of swedes . . 17 lbs. 
The ash in ihe'oats is in weight about one-fortieth 
part of the grain, and as 75 lbs. of oats will be 
eaten with the ton of swedes . . . 2 lbs. nearly 
The ash will amount to 19 lbs. 
Now the whole weight of dung from swedes will 
be about one-tenth of weight of roots . . 224 lbs. 
Weight of dung from corn is nearly one-half; 
therefore, from the oats there will be . .37 lbs. 
or 261 lbs.
