weeds and conserve soil moisture. The next best 

 method and perhaps the best and cheapest in 

 some soils and some seasons is the "double plow- 

 ing method": plowing deep (6 to 8 inches) before 

 July 1, giving some surface cultivation during 

 July and August and plowing rather shallow, 

 (4 to 5 inches) immediately after harvest, after 

 which the soil should receive such harrowing and 

 packing as may be required to prepare a favorable 

 seed bed. 



The author would suggest also the testing of 

 the listing method of preparing summer fallow 

 discussed in these pages (see page 000) and which 

 has been found so well adapted to dry farming con- 

 ditions in the western states, viz., substitute listing 

 in place of plowing in the "double plowing 

 method."
