" MiscELLAXEOus AWARDS to Agricultural Articles and essential improve-

In the Classes for which one prize only was offered, the Judges were em- 
powered to divide it equally between two competing Implements, if they 
considered them equal in merit. 
These offers were accompanied by the following 
" CONDITIOKS. 
" Steam Engines. — All Engines must be fitted with a Steam Indicator, ia 
addition to the ordinary Spring Balance, which Indicator must be proved by 
tlie Indicator of the Society. 
" Steam Cultivation : — 1. The weight of the Engine shall be deemed to be 
exclusive of coal, water, and rope, but to include the weight of the drum or' 
windlass. 
" 2. The Implements for Steam Cultivation must be tested by dynamometer,, 
if possible, and such experiments made as will enable the Judges to ascertain 
the relative value in usefulness of such Implements. 
" 3. The Steam Boiler must be provided with a pipe or tube, the thread 
of which mustbe equal to the 'half-inch gas-pipe thread,' for the purpose of 
attaching the forcing-pump of the Society. The Exhibitor may declare to 
work the Engine at any pressure he thinks fit, if the Judges are satisfied 
the Boiler would bear safely three times that pressure. The 13oiler shall then 
be tested by the forcing-pump to twice the pressure before the Engine is set to 
work, and the declared pressure must not be exceeded by the Exhibitor while 
be is working before the Judges. 
"4. Any Engine which is entered for competition, or for working in the yard 
of ' Machinery-in-motiou,' which, from defect in construction, or any other 
cause, is, in the opinion of the Judges and Consulting Engineer, unsafe, 
shall not be allowed to work on the Society's premises ; and further, the 
word unsafe shall be attached to the Engine during the remainder of the 
Exhibition. 
" 5. The trials of the Steam-Engines will be made with Llangennech coal." 
It will be useful here to transcribe the following clauses of the General Eegu- 
lations which related to the trials : — 
" The Specification must state the selling price of each article complete 
and in good working order; and each Exhibitor will be bound to execute 
all orders given to him in the Show-yard, at the price stated in this Speci- 
fication, and to deliver the Implements within six months of the close of 
the Show, on pain, in case of failure in such engagement, of not being again 
allowed to exhibit at the meetings of the Society. 
" In order to ensure a bond fide selling price being specified for competing 
Machinery, it shall be a condition that, if the price certified by the Exhibitors 
shall in tlae opinion of the Engineer Judge, or Judges, together with the 
Consulting Engineer of the Society, be stated so manifestly low, that the 
Exhibitor cannot consistently supply at such price, the Judges shall have 
2X)wer to decline to trj' such machinery. 
" Manufacturers of all Entries for the Prize offered by Lord Vernon, must 
enter into a contract with the Society to execute all orders (received by them 
within a period of three months from the close of the Show), at the price 
stated in their specification, and that the machinery supplied shall be iu all 
respects the same as that entered to compete for the prize."
