A second heap is built parallel and adjacent to the first and to the same 

 height. Then boards may be placed thereon and additions made to the 

 first until a convenient height is again reached. Usually about eight 

 feet is the most practicable height to attain. In removing the bags the 

 reverse order from stacking should be followe<l. 



Usually considerable time and labor is wasted when the lime is taken 

 from the bag and placed in the lime spreader. A convenient scheme is to 

 obtain a corn husking hook that can be fastened on the right hand; 

 the bag is placed on the screen of the spreader on edge. By means of the 

 hook an opening is made along the flat side and near the center, per- 

 pendicular to this slit and again near the center of the flat side of the 

 bag another opening is made. The lime may readily be removed by 

 turning the split side of the bag downward upon the screen.

Fjtjure 9. Vetch Does Net Thiive nii Many of the Light Soils Until They Have Been 

 Limetl. The Samples of Vetch Shown in This Figure Were Taken From Equal Areas of a Limed 

 and Unlimed Sandy Soil.

Since legumes are on the whole more sensitive to a lack of lime in 

 the soil than other crops it is generally considered best to appl}' lime 

 preceding these crops. When clover or alfalfa is to l)e seeded in wheat 

 or r3'e the lime should be spread after plowing and worked into the soil 

 when the seed bed is i)repared. If the seeding is to be made with oats 

 or barley the lime may be applied in the spring and worked into the 

 soil. When alfalfa or sweet clover is seeded without a nurse crop the 

 lime should be applied as soon as the ground is broken up so that it 

 may become thoroughly worked into the soil by seeding time. 



When vetch is seeded with rye the lime should be spread immediately 

 after plowing. In case the land is not plowed for any of the above 

 crops but is prepared with a disk or spring-tooth harrow, the lime should 

 be applied before the soil is worked.
