maintenance are also the same. There
have been added under the column with
Electric Plant two Items one OF which
is $4,000, constituting interest az four per
cent on $4,000 (the estimated value OF
the old Pump-House property: the Sc
cond item Of $3.50. Is the yearly loss In
transmission from the old Pump House 90
the New Pump-Housc fn the operation
OF electric pumps at the latter point This
loss amounts 20 twenty per cent OF the
40 HORSEPOWER noted under the caption
Power for Pumping" on page . OF SIr
Iranord s report. Twenty Per cent ~ 400
horsepower. az the cost OF eiEht cents
per kilowatt hour amounts % the value
indicated above. This constitutes q direct
charge against the operation Of the cleo
trio : liant which has heretofore not been

Two hundred and fifty dollars has been
introduced Cor line maintenance Of the
