Sir THOMAS HENDERSON:

asked the Minister of Agriculture whether double dipping, from the point of view of the prevention of sheep scab, has proved effective; whether the number of cases has decreased since it was introduced; and whether he can give the figures showing the number of certified cases reported in England for the years 1918, 1919, 1920, 1921, and 1922, respectively?

The reply to the first part of the question is in the affirmative. The double dipping of sheep has never been required generally throughout the country, but it has been applied from time to time in certain badly infected districts with very good results. The number of outbreaks of sheep scab confirmed in England in each year from 1918 to 1922 is as follows:

Sir T. HENDERSON:

Does the increase in the number of cases not show that double dipping has not been effective?

No, I do not think so. It is quite possible if it had not been for double dipping the cases would he much more numerous.

In what Bounties is double dipping practised?

I would require notice of that question.

Has the right hon. Gentleman considered whether the imposition of a penalty upon those whose sheep become affected would not be effective?

I should like notice of that question also.
