DRY LAND FARMING 



tions, is especially advantageous. The press drill still 

 further aids germination, especially in loose and spongy 

 soil, by so firming the earth that the seed is left under 

 most favorable conditions for quick and sure germina- 

 tion. The small one-horse disc drill may be so used that 

 drilling can be adjusted to spaces of different widths 

 between the corn rows.

The aim should be to avoid using the single disc 

 drill where the double disc will answer the purpose bet- 

 ter. Should it be necessary to use it on soil somewhat 

 lacking in moisture, the roller should follow the drill 

 and the harrow the roller. The soil will then be firmed 

 around the seed and it will not blow. The aim should 

 also be to avoid using the double disc drill on land over- 

 firm, rough or stony, or when the ground is so moist as 

 to preclude doing good work, nor should the press drill 

 be used on soil that bakes readily, save under conditions 

 that are exceptional.
