unfinished pitching of the slopes and top of the work and

also at the open and unprotected end. This is however

unavoidable under the circumstances, and would be more

for

than compensatedj

ed by the economy and convenience resulting

from the adoption of a form of structure largely inde

pendent of skilled labour, and for which but comparatively

little special plant and appliances will be required.
