instead of 11. If we did that I am afraid we should
have a big outcry against poor output.

It is in the nature of things very difficult to
get experimental experience of what we look upon as the
one extreme conditions namely, Town running with frequent
starts and stops and standing with lights on, such as
might occur during the next three months, not so much in
your own case, because you do a good deal of other running,
but in some of the cases which no doubt exist.

Would you like us to provide you with a dynamo
in which we have put the control brush back so that the
peak output when fully warmed up is the 8 amperes you
suggest, looking upon this from our point of view as an
exaggerated case arranged for experiment ? We have
such a machine which is already slotted out for control
brush movement and which we could send to you for the
purpose, you at the same time to return to us your present
machine which you say has an abnormally large output, so as to
