children are employed, careful supervision is necessary, 

 since they do not realize the difference in yield resulting 

 from careful and slo\'enly work. 



Beets should be thinned about the time they have four 

 leaves. Before this time, it is impossible to tell which 

 will be the strong plants. Later, the shock to the plants 

 that are left is so great that they do not easily recover. 

 ]\Iuch more damage is done by leaving beets too long be- 

 fore thinning than by thinning them too early. When 

 the farmer has a large acreage, he must begin a little too 

 early and continue a little too long in order to thin most 

 of the plants when they are the proper size. Planting on 

 two or tliree dates is necessary with large acreages in order 

 to make thinnhig at the proper time possible. 



The distance apart to leave plants depends on a number 

 of conditions. If the land is rich, the beets maj' be closer 

 together than if it is poor. If the season is short, they 

 may also be left closer in order to hasten an early maturity. 

 Under some conditions, the highest yield and sugar-con- 

 tent are obtained where the beets have from 144 to 160 

 square inches of surface to the plant. With the rows 

 twenty inches apart, the plants would be about eight 

 inches apart in the rows. This would give 39,200 plants 

 to the acre. If the beets weighed one pound each, a 

 perfect stand would give a yield of 19.6 tons to the acre. 

 In some places the beets are left as much as eighteen 

 inches apart, but so great a distance usually results in a 

 decreased yield. In a few places where the beets grow 

 exceptionally large, this distance may be justifiable. 



When the beets are close together the yield may be 

 higher, but the extra work of handling the smaller beets
