behind. This was hard work, and the plowing 

 was poorly done. The plow pictured on Egyptian 

 monuments was better shaped and was tipped 

 with iron. Long before the time of Christ, how- 

 ever, plows were made so that animals could be 

 hitched to them. Plows are now of various kinds, 

 adapted to the various types of soils as well as to 

 the various forms 

 of motive power. 

 The depth of 

 plowing also can 

 be regulated to 

 suit varying con- 

 ditions. Thus in 

 contrast with the 

 old, the modern 

 plow is a fairly complex machine. 



Sowing. - - Following nature's method of seed- 

 ing, man first scattered the grain over the ground. 

 Practice made the sower so skillful that the re- 

 quired amount of wheat was scattered evenly over 

 the field. Pictures of the ancient sower clearly 

 bring out the rhythmic tread and the swing of 

 the arm as he threw the grain from the bag which 

 hung from his shoulder. This method of sowing 

 was called broadcasting, and is still followed where 

 farms are small or where the standards of farming 

 are low. Hand sowing was hard and tedious work. 

 In time mechanical broadcasters came into use
