4. Every macliine must be delivered at the depot on the trial ground, in 
proper -working order, before 9 a.m. on the first mornino; of the trials. 
5. Exhibitors are expected to provide their own drivers and attendants, 
but the Society reserves the right to provide men and to work any machine 
if a competitor be absent or not ready, or who says that his men are absent, 
after due notice has been given to him to bring his machine out for trial. 
6. Before starting work, the competitor must declare the number of men 
and horses required by his machine. If lie, personally, or any other extra 
attendant, not included in such declaration, should render any actual assis- 
tance in working or adjusting the machine during the trial, the fact will be 
noted by the judges. 
7. Each machine will be allowed a preliminary trial not exceeding one 
hour's duration with each material it may be required to compress. 
8. The trial will last till not less than 60 cwt. has been pressed by horse or 
steam power,''and till not less than one ton lias been pressed by hand power. 
9. No trial will be considered as of any use unless the bales have such a 
form and density that 50 cwt. of pressed material can be loaded into a rail- 
way truck having a capacity of 25 cubic yards. 
10. The machines in Class 1 will be tried on straw, new hay, and old 
hay. The straw-pressing machines in Classes 1, 2, and 3 will be tried with 
straw and new hay, and, should any competitor desire it, with old hay also. 
Tlie hay presses in Class 4 will be tried with old hay only. 
11. The following will be the points awarded: —

The trials commenced on July 3. and vs^ere continued, day 
by day, until the evening of July 9, when no less than forty-seven 
separate experiments had been concluded. The presses were 
not tried in the order of their classification, a commencement 
being made on Class 3, but it will convenience readers of the 
Journal to describe them in that order, even at the expense of 
some inversions of dates. For the same reason, the results of 
the trials will bo displayed, class by class, in a tabular form, to 
which, instead of a too detailed account of each trial, the reader 
in search of general conclusions is referi'ed.
