Report on the Trial of Dairy Implements 
of the operation, is fatal to the production of a really fine quality 
of butter ; by rapid churning the fatty globules may be so 
broken up, that it sometimes becomes impossible to get the 
butter at all, and in this case we have known the ignorant and 
superstitious attribute it to the power of witchcraft. The suc- 
cess of Mr. Ahlbom, with his small dashers, in the milk-trials, 
and that of Messrs. Thomas and Taylor's " Peg " arrangement, 
with the cream, fully confirm our opinion that numerous and 
large dashers are a mistake ; though both these competitors 
finished at a high speed, the percentage of butter, when washed 
and removed from the churn, varied from 12i lbs. (the highest) 
to 11^ lbs. (the lowest). After having been passed through 
Ahlborn's butter-worker, the highest was ll^lbs., and the lowest 
lOf lbs. In order that each individual competitor should not 
have cause to complain of having been placed at a disadvantage, 
we decided to submit the seven which in our opinion possessed 
the highest order of merit to a final trial on Friday morning, 
and arranged that the competitors should have nothing to do with 
their working, but that the churns should be driven by the So- 
ciety's servants. They each had an allowance of 21 lbs. of cream, 
at a temperature of 61^ Fahrenheit. The butter was washed 
and weighed from the chum, at once passed through the butter- 
worker, and again weighed : it gave from the churn 4 lbs. 1^ oz. 
and 3 lbs. 10;^ oz. as the highest and lowest respectively ; after 
having been passed through the butter-worker, the quantities 
were reduced to 3 lbs. 15 oz. and 3 lbs. 8| oz. respectively, as 
shown in the accompanying Table, p. 145. 
Guided by the quality of the butter and the general results of 
the repeated trials, we awarded the first prize to Xo. 2244, 
Messrs. Thomas and Taylor; highly commended Xo. 1973, 
Robinson and Richardson ; and commended Xo. 2342, T. 
Bradford and Co. 
Class IV. — Mechanical or Automatic " Butter-workers," 
SUITABLE FOR LARGE DAIRIES AND FOR FACTORIES. 
There were 4 entries and onlv 3 competitors in this class. 
Mr. Aldborn's machine (Xo. 2118) consists of a circular' table, 
slightly sloping from the centre to the circumference, with a rim 
or hoop standing some 2 inches above the edge of the table. 
Round the outer ed^e of the surface of the table runs a shallow 
groove, into which trickles the expressed fluid, which flows 
through a pipe into a vessel set underneath. The butter is 
placed on the table, and is carried under a fluted roller driven 
by hand. Motion is communicated to the table by a small 
counter-shaft and pinion movement. The roller is held in posi- 
tion by a thumb-screw, and the pressure regulated at pleasure.
