incidence of Malaria were stationed in
districts when Anopheles maculipennis was
present. The infected soldiers then infected
the mosquitoes who returned the compliment to
other soldiers and so on. However these
outbreaks were limited in size and were not
sustained.
It is always possible, especially with
increased travel overseas that infected people
will return or arrive in Britain with Malaria.
The mosquito is innocently waiting in its
breeding grounds to assist in transmission.

THE HISTORY OF A GROUP OF FIELDS
My story starts about 15 years ago when I
noticed a rise in the soil about 20 yards wide
and no more than two feet high across a field
and also across the next -field. Presumably
the -feature was older than the -fields. Only
very recently did I read that it was a baulk or
access road to the strips in an open -field.
The strips were presumably at right angles to
the baulk on both sides. I assume the baulk
was -formed by using the plough to move the soil
-from the strips to make the ridge. Conse-
quently the land both sides was made lower and
the depth of topsoil less which is very clear
on one side especially, even today.
