rows of early celery; lettuce with early cabbage; 

 radishes with beets or carrots; corn with squash, 

 pumpkins or beans, and horse-radish with early 

 onions or cauliflower. 



Irrigation for arid soils and drainage for wet 

 or clayey soils, are the two opposite methods 

 which bring astounding results. Any sort of 

 drainage is better than no drainage, but the 

 best form so far discovered is the tile drain laid 

 about two and a haK to four feet below the 

 surface. This carries away the surplus water 

 and prevents the roots of the crops being suffo- 

 cated. On the other hand, irrigation supplies 

 to the dry lands the moisture they need. The 

 tremendous irrigation works carried on by the 

 Government in the sandy, hitherto barren, 

 reaches of the west, are bringing results even 

 more tremendous than the works. 



Hard, wet soil will not grow crops and here 

 is where the advantage of draining comes in. 

 Drainage deepens the subsoil and removes the 

 water; it deepens the surface also and makes 

 more of the plant food in the soil available. 

 Wet soil is sticky and hard for the seeds to push 

 their way through; but drainage will improve 

 its texture and make it crumble and fall apart 

 easily, or as the experts say, it will make it 

 " friable." At the same time it will prevent it
