bricks, in place of hand-labour. A serious obstacle to the development
of this industry is the short period (from three to four months in
summer) during which the manufacture is pursued. To obviate this, special,
well constructed drying kilns have been introduced in one or two places
to render it possible for the unbaked bricks to be dried quickly and
thoroughly before their insertion in the baking-kiln.

In the carboniferous formation of Skåne, alternate strata of coal
and fireproof clay occur in many places. By reason of this convenient
supply of fuel, a very extensive earthenware industry has arisen in
that province; about 40 % of the coal raised is used in the manufacture
of fireproof products out of the accompanying clay, such as fire-bricks,
possessing the power of resisting fire to a greater or less degree (elasticity
of compression 100—200 kilograms per square centimeter), clinker-baked
hard bricks (elasticity of compression 300—500 kilograms per square
centimeter) for canal structures, facades, etc., and salt-glazed
drainpipes and earthenware of various kinds.
Of the factories making these goods, Höganäs deserves special
notice. It was founded in 1798 but did not begin to make fire-bricks
until 1827. The salt-glazed earthenware bottles, etc., from Höganäs have
long been highly prized, and in recent years the company have extended
the range of their manufacture to include ornamental articles, decorated
in majolica colours, and also discharge-pipes, etc., which, when made of
