ICE CREAM.
Ten samples were taken during the year. Eight were placed
in Grade I, one in Grade II, and one in Grade III.
PIGGERIES.
There are eleven piggeries in the district. This indicates a
decrease on the year, and is part of a trend against pig keeping on
a small scale, noticeable since shortly after the war. Approximately
1,553 pigs are kept, one large piggery accounting for 1,000 animals.
34 visits were paid to these piggeries.
