3. Fly in Turnips. — Lord Thanet, and Mr. Grey, both emi- 

 nent agriculturists, have communicated to the Board of Agricul- 

 ture their conviction from experiments, that lime sown by 

 hand, or distributed by a machine, is an infallible protection to 

 the turnip, against the ravages of the fly. It should be applied as 

 soon as the turnips come up, and in the same daily rotation, in 

 which they were sown ; and the lime should be slaked imme- 

 diately before it is used, unless the air is sufficiently moist to 

 r<ndcr that operation unnecessary.
