Badly tangled fields make the j)r()gress of one of these machines 

 slow, but it is remarkable with what precision the chain conve^^ors 

 right the stalks. The adjustment is accomplished by tilting the 

 machine forward or backward b}^ the tilting lever, according to 

 whether it is desired to lower or raise the points of the dividers. As 

 the weight is almost evenly distributed on either side of the main 

 shaft, it takes but a very little power to bring the dividers into the 

 desired position. 



There are two types of these dividers — the vertical (see fig. 11, 

 p. IS) and the inclined (fig. 15). For the vertical it is claimed that 

 little jostling is given the corn, decreasing the danger of knocking off 

 ears, while advocates of the inclined pattern claim to accomplish the

same result by allowing the stalks to recline against the inner jaw 

 and be carried backward between the fingers of the conveyor chain 

 on that side. 



Owing to the great variation in height of corn, even in the same 

 field, the binding attachments are given great range of operation. 

 In some machines they are placed as high as 32 inches. On machines 

 of this range it is customary to have two needles, each covering half 

 of the variation in the position of the knotter. With such a large 

 range as this it is possible to tie the bundles sufficiently low without 

 raising the stalks any great distance, thereby reducing the work 

 required of the machine. In most machines the motion is taken
