becomes partially rolled up before it starts, and is the more 
likely to roll back during its transit. In the case of Taskers' 
(No. 4839), the rolling back occurred at the top of the trough, and 
was due to a curve upwards in the trough itself, the upper 
division ^- ing too tightly braced up. When straw and hay 
were broug ht back and dropped under the machine instead of 
upon the rick it was generally due to one of two causes, either 
the shape of the chains and rake-heads afforded lodging places 
for the material, or else the ladder was driven at too great a 
speed, and the hay, instead of dropping perpendicularly as soon 
as the teeth were inverted, was swished down obliquely. The bad 
results of the quick motion were still more clearly seen in the 
trial with sheaves, for the rattle of the quick moving ladder in 
Nos. 169 and 5104 tended to shake out the corn, and when the 
sheaf left the top of the trough, instead of dropping soberly down, 
it was usually sent spinning, like a clown turning somersaults in 
the air. The trial with sheaves was in almost every respect 
a more severe test than with hay and straw ; three machines
