igO SCIENCE OF SUCCESSFUL THRESHING. 



siderable grain so that the exchange of sacks may be made 

 even in fast threshing, without danger of choking the ele- 

 vator by obstructing its delivery. The grain may be de- 

 livered in bulk into wagons driven along side the separator 

 as the end of the spout is a sufficient distance from the 

 separator to make it unnecessary to back the wagon up to 

 the machine. Where grain is to be sacked^ an empty sta- 

 tionary wagon may be used to sack in, thus avoiding the 

 necessity of lifting the sacks of grain into the wagon which 

 hauls them away. The long spout is provided with hooks 

 to hold the sacks. The Number Two weigher is used very 

 generally in the localities where the threshing is done in the 

 open field. It is the only suitable grain-handler for use in 

 connection with portable-bins, such as are quite generally 

 Used in the northwest. The spout is long enough to deliver 

 the grain into these bins and the weighing apparatus auto- 

 matically records the number of bushels threshed. 



The Number Three Weighing-Bagger. This attachment 

 is intended for use in putting the grain into sacks on the 

 ground and it can only be used on the left-hand side of the 

 separator. It has the same weighing mechanism as the 

 Number One and Number Two Weighers. 



The Number Four Bagger. This grain-handler does not 

 weigh the threshed grain, but is used simply to elevate it 

 to a sufficient height to run into sacks. In order to keep 

 the men sacking always on the windward or clean side of the 

 separator, it is often desirable to change the bagger from
