Repoi't on the Exhibition of Implements 
The spirit stands at zero on the index pLnte when the line of 
sip^ht is horizontal, and it rises or falls as the line of sigfht is 
elevated or depressed. This instrument will therefore be useful 
for draining, and all similar purposes, as it will not only indicate 
the true level, but may be set to show any rise or fall per yard or 
chain that may be required from the place where it stands to 
any point to which it may be directed. 
Manv other implements possessed considerable merit, but 
could not be distinguished by prizes, as the number of these were 
limited. Several models were exhibited by Mr. Bullock Web- 
ster, especially one of a tile-kiln, of a new construction, by which 
he states that fuel is economised, and the heat, after being used in 
burning, may be made available for drying purposes. Also the 
model of a portable drying or '•' desiccating " apj)aralus, by 
which air may be heated and driven by a " fan" into any cham- 
ber or other receptacle, and used for drying peat, wood, grain, 
roots, and other substances. 
Mr. Read, of Regent Circus, London, exhibited several fire 
and other engines, injecting instruments, probangs, »Scc., of great 
and general utility. 
Messrs. Young and Co., of Edinburgh, exhibited various speci- 
mens of wrought-iron railway and field gates, of commendable 
workmanship and contrivance. Also wire-netting of varied size 
and form, and unusual cheapness. 
Mr. Crosskill exhibited aportable railway, with turn-table, wag- 
gons, trucks, and all the necessary appliances, for claying, marlmg, 
excavating, or in other ways removing heavy substances. This 
a])paratus might be essentially useful in certain circumstances. 
Mr. Henslovv, of Holmes Chapel, Cheshire, showed a " rever- 
beratory " churn of recent invention. The principle is new, and 
requires very little power in the working. The dash-boards are 
driven by a crank on the axle of the fly-wheel, which gives them 
a reciprocating, or back and forward motion. It was not con- 
sidered to agitate the liquid sufficiently, but this defect may per- 
haps be remedied. 
Mr. Hill, of Brierly Iron works, Dudley, Worcestershire, 
exhibited a wrought-iron rick- stand, the best of its kind, having 
that most important merit in an agricultural implement — sim- 
])licity, as it has neither bolt nor screw in its whole construction. 
The iron used is of the T shape, which is the strongest form. 
The ends of each i after are turned in the form of a gate-crook, 
and made to drop easily into holes formed in the flanges of each 
joist. The rafters being all of equal length, each will fit any 
place, so that they cannot get out of order, and may be put 
together in a few minutes by a common labourer. 'J he same 
exhibitor had a great variety of wrought-iron gates, hurdles, rod
