machine. The passage of the hay from one end of the dryer 
to the other took from 1^ to 2 minutes. Sometimes a wisp 
which had been only partially dried was taken back to the 
feeding end and operated upon again. What was very notice- 
able in this trial was, that while some of the hay was com- 
pletely desiccated, so that it smelt like malt, and could be 
rubbed into powder in the hand, some of it emerged from the 
dryer quite clammy. Of course this is partly caused by the 
unequal condition, as regards moisture, of the hay itself; but 
it is still more due to the great inequality of the temperature 
at different parts of the dryer. Mr. Anderson made the follow- 
ing observations of the temperature of the air at different points 
on the outer edge of the table, on the lee and windward sides 
of the dryer : —
