It will be observed by reference to the above summary that in January and
December the figures for deposit and sulphur dioxide are considerably higher than
for the summer months. This is general experience. Since industrial and non-domestic
pollution does not vary a great deal according to the season of the year the increase
in winter pollution must be ascribed very largely, if not entirely, to the increase of
domestic pollution due to open fires. The increase in deposit and sulphur-dioxide
in the winter is, therefore, a measure of the increased pollution caused by the
inefficient combustion of raw coal in the ordinary domestic grate.
The Council approved the attendance of one of its senior Inspectors to a three
day course on modern domestic fuel appliances arranged by the Coal Utilisation
