is contained in a building consisting of a circular wall covered with a
wrought iron roof. The holder itself is telescopic, and is capable of
holding 3½ million cubic feet of gas. The accompanying illustrations (Figs.
1 and 3) are a sectional elevation of the holder and its house and a
sectional plan of the roof and holder crown. Having a capacity of close
upon 3,200,000 Austrian cubic feet, this gasholder is the largest of its
kind on the Continent, and is surpassed in size by only a few in England
and America. By way of comparison, Hamburg possesses a holder of 50,000
cubic meters (1,765,000 cubic feet) capacity; and there is one in Berlin
which is expected to hold 75,000 cubic meters (2,647,500 cubic feet) of
gas.
