trough. By varying 

 the depth of the groove 

 and the width of the 

 shoulder on the adjoin- 

 ing side the board can 

 be made to sow any 

 quantity desired. One 

 of the outer edges of 

 the board is beveled 

 far back on the under 

 side so as to offer no 

 obstruction when the 



seed is dipped. Two men operate it, one at each side of the bed. The 

 board is dipped with a swinging motion into the trough and then lowered 

 and held close over the drill to be seeded ; the hinges are bent upward, and 

 the seeds fall into the drill.
