 is not established before that time. 



The bent should be planted out at 6 inches apart. It is only 

 necessary to put in one stalk with at least three joints, and it will 

 grow freely. Broom seed may be sown at the time the trees are 

 planted, as the planters naturally mark the sands with their feet, 

 and the seed blown into the tracks secures itself. The cost of 

 covering the hill in this way is about 35s. per acre, the pulling 

 of the bent being the most expensive part of the work.
