490 The Trials of Thresking Machines at iJoncaster. 
should have been, but in the oats good work was made. The 
quantity threshed was small compared with the other machines. 
Oibhons and Rohinson's Machine. — On the morning of June 
18, the trial of this machine was commenced, some little time 
being expended in its adjustment. The following are the results 
of the three runs made on that day. During the hour's run 
with wheat 7,732 lb. of sheaf corn were served out, the pi-oducts 
being 2,8^9-5 lb. of firsts, 75 lb. of seconds, 54'5 lb. of thirds, and 
recovered by re-threshing, 13^ lb. The power taken was 
11-05 h.p. 
In the run with barley 6,476 lb. of sheaf corn were served out, 
the grain products being 3,085'5 lb. of firsts, 186-5 lb. of seconds, 
74*75 lb. of thirds, and recovered from re-threshing, 32-75 lb. 
Of oats the sheaf corn served out was 2,996 lb., and the pro- 
ducts in grain were 1,135-5 lb. of firsts, 25-25 lb. of seconds, 
16-5 lb. of thirds, and recovered from re-threshing, 51b. 
A second trial with wheat was made with the following 
result. The weight of sheaf com served out was 5,852 lb. ; the 
products in grain were 2,190-25 lb. of firsts, 29-75 lb. of seconds, 
21*25 lb. of thirds. The time occupied by this run was 35^ 
minutes, and the power taken was 10-04 h.jo. 
In this trial the proportion of weight of grain to weight of 
sheaf corn is almost identical with the first run in wheat. The 
feeding was very indifferent, and an allowance of 8i minutes had 
to be made consequent on the machine becoming choked. 
The wheat-straw and cavings were clean threshed, the chaff 
being remarkably free from dust and corn. Good work was made 
in the barley trials, and the chaff from the oats was the best 
the Judges had seen. The machine would have done more work 
had the feeder been well served. 
Foden's Machine. — On the afternoon of the 14th inst. 
the trials of this machine were made. Commencing with the 
wheat run of an hour, the amount of sheaf com weighed out was 
8,1441b., the resulting grain being 3,102-5 lb. of firsts, 101 lb. 
of seconds, 21|lb, of thirds, and recovered from re-thre§hing 
19 lb., the power taken being 10-44 h.p. 
The quantity of barley in sheaf served out was 5,81 2 lb., the 
resulting grain products being 2,7201b. of firsts, 105-5 lb. of 
seconds, 21 lb. of thirds, and 23| lb. recovered from re-thi"eshing. 
The power taken was 10-07 h.p. 
During the half-hour's run with oats, the corn in sheaf 
served out was 4,6261b., the resulting grain products being 
1,712-25 lb. of firsts, 30-25 lb. of seconds, 11 lb. of thirds, and 
from re-threshing, 7^ lb. The power taken was 11-35 h.p. 
A second trial with wheat was made, the duration of which
