Franh Chem Bugs Motor Boat for
the MarbIehead Race.

The manufacturers who are exhibiting at the
National Motor Boat and Engine Show at thc
Grand Central Palace are more than satisfied with
the amount of business done. considering the time
year and the stringency in the money market.
Many orders have been booked and 1t IS piaiil
that hundreds of persons are taking time by the
forelock and making plans for their next sunIner
vacation. Interest in the show does not lag Inc
crowd yesterday afternoon was bigger IMAM usual
and III the evening the aiSles were uncontortaDIy
crowded. much so, in fact. that many persons
left after a cursory view, with the fixed determ-
nation to go back this afternoon tomorrow to
study some of the exhibits more closely.
The sale which attracted most interest yesterday
was made by H. S. Hart, of the Stamford Motor
Company. He contracted to build 4o-tout cruz

the engine has slowed down almost 10 the stopping

starting the engine in the opposite direction. The
spark is then brought to the proper running posi-
tion. With a single cylinder engine this method
of reversing is not absolutely reliable although IN

With q multiple cylinder motor there is less
chance or failure. and with practice the reverse
can be worked almost to a dead certainty.
One of the busiest parts OF the show Is that part
known as the back of the hall" for want of
better name. Here there is a pleasing variety OF
all those things which to make motor boat

one supplying heat for cooking purposes and the
other furnishing for incandescent mantle
