plenty of cut mangel wurzel and a little hay -chaff; their lambs ran 

 through the hurdles on a good pasture of red clover. The other lot of 

 ewes were left at large in the common way on white clover and trefoil ; 

 their lambs, also, had a good piece of red clover to feed upon : both lots 

 of lambs had a small quantity of peas. 



" Experiment No. 6. — On the 35th pf May the lambs from each of the 

 lots above described were weighed aUve, and again on the 33d of June, 

 when the result was as follows : 

 Those lambs belonging to the ewes fed on mangel wurzel, gained lbs. 



each, on the average, in 28 days 31 



Lambs from ewes fed in the usual way on clover and trefoil, 



gained each, in the same time 18 



Diffterence each lamb in favor of mangel wurzel 3 



" This statement, as well as others preceding, of lambs gaining in 

 live weight of about 30 lbs. each in 38 days, may appear startling to 

 those unaccustomed to weigh them alive, but this is no uncommon 

 weight for lambs to gain, if well fed and attended to in the early sum- 

 mer months. Those ewes fed on mangel ate about 33J lbs. each per day, 

 care being taken that their lambs had none of it on those days that the 

 food was weighed, and, unlilce those ewes fed on it in March, (see 

 Experiment No. 3,) I found them to thrive and do well with it. It 

 should, however, be remembered that the summer of 1846 was veiy 

 favorable for the use of mangel, the weather being very dry the whole 

 of the period the above trial was carried on, and, consequently, more 

 unfavorable for those ewes fed on the clovers, which, toward the end of 

 the time, were nearly dried up. From this trial it appears that mangel 

 wurzel is of great use as a summer food for sheep, and as it will keep a 

 long time, if properly stored the preceding autumn, must be very useful 

 in a dry season for any kind of stock. * * * * 



" Having proved by many experiments the advantage of putting 

 young lambs, after weaning, upon old keeping — ^namely, pastures that 

 have been stocked from the commencement of the spring — over 

 eddishes or pastures that have been previously mown the same season, 

 I will state one experiment as a sample of the rest. In the year 

 1834, I put a lot of lambs on some old sainfoin, having a few tares 

 carried to them, and another lot of lambs were put on young sainfoin, 

 or an eddish which had grown to a pasture; these, also, had some 

 tares. Each lot was weighed at the commencement, and again at 

 the end of the trial: 



"£!;t^rment No. 7. — Gain in weight of a lot of lambs fed on lbs. 

 old sainfoin, from July 10 to August 10, each on the 



average 14J 



Lambs fed on sainfoin eddish, gained each in the same time;. &j 



Difference, 6 



" Experiment No. 8. — June 10, 1844, ten lambs were weaned, and 

 weighed alive, and put on red clover, with some tares and beans 

 given; on the same day, ten lambs were weighed alive, remaining 

 with their dams on white clover and trefoil, but allowed to run 

 through hurdles upon good red clover. Bach lot was weighed again
