There's a new storage battery been
invented by a New Jersey man, which does as well as the third
rail or the overhead wire. It was after reading about his battery
that I thought of a plan for mine. It isn't anything like his;
perhaps not as good in some ways, but, for what I want, it is
better in some respects, I think. For one thing it can be
recharged very quickly."
"Now Tom, look here," said Mr. Swift earnestly, laying aside
his papers, and coming over to where his son sat. "You know I
never interfere with your inventions. In fact, the more you think
of the better I like it. The airship you helped build certainly
did all that could be desired, and--"
"That reminds me. Mr. Sharp and Mr. Damon are out in it now,"
interrupted Tom. "They ought to be back soon. Yes, Dad, the
airship Red Cloud certainly scooted along."
"And the submarine, too," continued the aged inventor. "Your
ideas regarding that were of service to me, and helped in our
task of recovering the treasure, but I'm afraid you're going to
be disappointed in the storage battery. You may get it to work,
but I don't believe you can make it powerful enough to attain any
great speed.
