THE IMPLEMENTS OF THE FARM. 19 



Corn Screens are connected with winnowing machines, 

 either oscillating sieves of the proper mesh with a certain 

 incline' given to the surface enabling the discharge of the 

 larger grain; or revolving wire cylinders with a sloping 

 axle, into the upper end of which the hulk is delivered, and 

 from the lower end the head corn is discharged, while 

 dust and small seeds escape in the descent. 



Clover and seed shellers are generally portable. The 

 shelling barrel, the drum and beaters, being wholly made 

 of iron, is placed under the dressing apparatus, and to 

 which the shelled seed from the barrel is raised by elevators. 

 The clean seed is delivered into sacks, and a side spout 

 conveys the shivers away from the chaff. 



The different bushel and other measures, hand riddles, 

 sieves, scoops, weighing machines, and sack barrows, do 

 not require comment. 



Pood Preparing Machines. Chaffcutters. Where all 

 the straw is cut into chaff, it is best done directly from 

 the threshing machine, the cut chaff being carried to the 

 different stores by "travellers." Maynard has added a 

 yealming machine to his chaff engine delivering the straw 

 combed out from the threshing-machine ready for the chaff- 

 cutter. But when hay is cut along with the straw for cattle 

 food, the work of chaffcutting is done separately. In this 

 case, if there is not water power, it is generally better to 

 have a separate engine from that used in threshing for 

 driving all cattle-food-preparing machinery. 



Corn Grinding and kibbling machines of the ordinary 

 kind consist of French burr, and steel, mills. The former 

 are made two ways 1, horizontal runner and bed, and 2, 

 vertical runner and bed. Steel mills for grinding are
