Implement Shoio at Bury St. Edmund's. 
inoist:>ne(l with liquid manure or water, bone enters into putre- 
faction, and becomes a much more soluble and energetic manure 
than ordinary bone-dust. 
An excellent way of rendering bone-dust soluble, it may also 
be mentioned, is the Norfolk plan of putting it in alternate layers 
between fresh farmyard-manure, and letting both ferment together 
in a conical heap, covered up with earth to prevent the loss ot 
any fertilising matter, and to secure it from penetration by heavy 
rains.

X!. — Report on the Trials of Fixed and Portable Steam-Engines 
at the Bury St. Edmund's Meeting, 1S67. 
The following Report was received by the Stewards of Imple- 
ments at the Bury St. Edmund's Show too late to be inserted in 
the last Journal. 
To the Council of tlie JRoyal Agricultural Society of England. 
My Lords and Gextlemex, — We have the honour to hand you our Eeport 
of the Trials of Fixed Steam-Engines and of Portable Steam-Engines at the 
Meeting of the Society held at Bury in July last. 
Fixed Steam-Engines. 
We awarded the First Prize to Messrs. Clayton, Shuttlcwortli, and Co., 
who exhibited an engine well designed and thoroughly well made, which 
showed a very low consumption of fuel. The cyhnder was steam-jacketed, 
and the jacket was in full use during the trial, although, from the relative 
positions of the Society's boiler and the engines to be tried (it not being 
possible to run the condensed steam from the jacket back to the boiler), the 
water was suffered to escape. 
The Second Prize was awarded to Messrs. Tuxford and Sons. This engine 
also had a steam-jacketed cylinder, and was in other respects well designed 
and very well made ; but during the trial the steam was not kept on the 
jacket, and we believe that this had the effect of increasing the amount of 
steam used. 
The Engine of the Reading Iron Works Company we highly commended, 
as in its consuinption of fuel it was but little above that of Messrs. Tuxford, 
and the workmanship was very good. This engine was furnished with a 
means of varying the expansion without stopi)ing the engine. This is an 
extremely valuable adjunct to an engine when it is in charge of an intelligent 
driver. 
We commended the Oscillating Engine of Messrs. Deacon and Wood, 
because, although a very cheap engine, it gave a very good result as to con- 
sumption of fuel. 
As regards the Portahlc Sfcaia-Eiiffiiics, whether single or double cylinder, 
these, so far as noticed in our Award sheets, were put through a double 
Uial, the second being at 50 per cent, of load in excess of the first.
