§ Sir B. PETOasked the Minister of Agriculture whether he has come to any decision as to the compulsory dressing of all cattle with derris powder solution with a view to the extermination of the warble fly?
§ Mr. ELLIOTAs to the general question of compulsory measures, I would refer my hon. Friend to the reply I gave yesterday to questions by my hon. Friend the Member for East Fife (Mr. H. Stewart), the hon. Member for the St. Rollox Division of Glasgow (Mr. Leonard), and my hon. Friend the Member for Aberdeen, North (Mr. Burnett). I fully recognise the advantages of a potent derris root preparation for the destruction of warbles.
