Notice. 
Each machine is to be brought to position folded as for travelling. 
A first trial will be made with each machine with hay and straw not weighed. 
A second trial will be made with each machine with numbered sheaves of com. 
Final trials will then be made witli sekcted machines with weighed sheaves of 
corn, and, if considered necessary, with hay and straw again. 
At the same time experiments will be made to determine the power requii-ed. 
Each exhibitor had thus an opportunity of ascertaining before- 
hand the exact nature of the trial that would be made. In 
order to test the elevation of each machine and the cleanness of 
its delivery, an arrangement of p<;les and rick-cloth was made 
in the rickjard, as shown in the illustration (Fig. 1), where the 
rick-pole on the right hand is marked with a scale of feet, a 
rick-cloth is thrown across the horizontal bar, and a rope from 
each end of this bar is passed over a pulley at the top and 
fastened near the base of the upright pole. By means of these 
ropes the horizontal bar was set to any given height, representing 
the height of the stack ; all hay or corn that dropped to the 
right of the cloth was counted as put fairly upon the stack, all 
that fell to the left was counted as wrongly delivered. 
In Table I. are recorded the observations made, and the results 
obtained, during the three trials of each machine with hay, 
straw, and sheaf-corn, respectively. Fifteen machines were tried, 
but as one of them failed in each run it is not entered in the 
Table. 
The machines were parked outside the rickyard. Before 
bringing it into the yard each one was folded up as for travelling 
or putting away in a shed, and its extreme height, length, and 
breadth were measured. These dimensions are entered in column
