moisture therefore calls for thin planting that 

 there may be less danger of "firing" before the 

 crop matures. If the season is well advanced 

 and the soil moist and warm so grains shoot 

 up rapidly they do not take time to stool or make 

 tillers. The reason that some grains are more 

 drouth resistant than others is that they have 

 grown in dry regions so long they have lost the 

 habit of tillering to a large extent and also pro- 

 duce less leanness to pump moisture from the 

 soil. The following seed table will be found very 

 useful for dry farming. The amounts of see*] 

 given are based on the very best condition of seed 

 bed, planting at the right time and with a drill 

 which does the work in the best possible manner. 

 The farmer whose seed bed is in poor tilth or 

 dry, or who plants late or with poor methods, 

 should increase the amounts of seed recom- 

 mended by from 30 per cent, to 100 per cent.
