Moreover, according to Professor Riedler, the consumption of steam by
the new Schneider engines will be only 5.3 kilos. per horse power and
per hour as compared with some of the large engines requiring 9
kilos., and the Cockerill engines--using 8 kilos. per hour, not to
speak of the older motors that are very extravagant in the use of
steam. The St. Fargeau station is worked under a further disadvantage.
The constantly increasing demand from subscribers taxes the resources
of the station to their fullest extent, so that practically there is
no reserve power.
In the new installation the work will be equally constant, but care
will be taken always to have a sufficient reserve. Electric lighting
will form a considerable part of the duty to be done from this
station, and in all cases it is intended to work with accumulators, so
that the resistance to be overcome by the engines, so far as this part
of the duty is concerned, will be well known and uniform. The
engineers of the Compressed Air Co., of Paris, have during the last
five years acquired an experience which could only be attained at a
high price and at the expense of a certain amount of failure; this
period, it is claimed, is now passed, and in the new installation it
is possible to put into practice all the valuable lessons learned at
St. Fargeau, to say nothing of the more favorable natural conditions
under which the extension is being started and the improvements in the
compression of the air made by Mr.
