{IE previous issues of this series of booklets, telling the 
Story of Pittsburgh, as it is related in the great busi- 
ness which this city is doing, have dealt with the 
chief industries of the community, which are most widely 
known. The object of the First National Bank at Pitts- 
burgh, however, has not been merely to speak of the basic 
industrial enterprises, but also to inform the world of many 
ather lines in wich Pittsburgh is prominent. 
Naturally enough, in an industrial metropolis known all 
over the world as “the Iron City,” the metallurgical indus- 
tries are by far the most important. Without them other 
industries could not exist, and therefore previous issues of 
these booklets have handled Iron and Steel in a thorough 
manner, and in a way which has been a great satisfaction to 
Pittsburghers at home and Pittsburghers abroad, and to the 
:ustomers of Pittsburghers in all parts of the world. 
Then there was a time when Pittsburgh was known as 
“the Natural Gas City.” At that period natural gas was 
produced in vast quantities close to the city limits, and 
scarcely any other fuel was used in the community, whether 
for homes or for great manufacturing plants. The tremen- 
dous quantities of gas consumed cut deeply into the supply, 
and it became necessary to go further and further away, 
drilling wells and bringing the gas from many miles distant. 
Pittsburgh is still the greatest user of natural gas of all the 
cities of the world, especially in the winter, when dwellings 
are heated, as well as many factories deriving fuel for manu- 
facturing purposes. These factories can get much more gas 
in the summer. time, when residences are using but little, 
and the additions then to their fuel supply, from the natural 
gas fields, maintain the steady use of Nature’s fuel.
