You see. Crhe motor, on the ground be-

Yes 1t is a matter for practical trials"
When shall you begin them?'

The piano wires by which the two keels

Yes. They must be of exactly their cal
culated length. His failure to attend to
TINS detail personally cost De Bradsky his
life, you will remember. There was more
strain on some wires than on others and
so they broke. one after the other the
strain changing continually as they broke,
one by one l cut the wires myself, and 1
see every one put in place. Tomorrow I
shall take the airship out and balance IT.
Then the speed trials
What speed do you think you are sure
to haVe?'
What is Necessary.
Il ought to have fifty kilometers thirty
one miles, per hour Otherwise / shall be
disappointed. l have got to have forty
kilometers per hour
"Why?'
I'm order to be sure to make the thirty
kilometers per hour required by the ST.
Louis competition rules. You know, the
prescribed course, is around three captive
balloons, each side of the triangle being a
httie over hve klometers; that is to say,
sixteen kilometers in all. The winner OF
the prize must do 1T in half an hour
Even If he be the only competitor?'
Worse than that" said Santos. He
must do 1t three separate times. 1t will
not be sufficient to succeed once
How does that minimum speed compare
with that of the Deutsch prize competition
which you won in Paris when you rounded
the Eiffel tower?''
The st. Louis competition demands As
per cent more speed. 1t is very stiff
How about the dangers-housetops etc3'

glad to say that the course is all over

How about the wind? Have you looked
into st. Louis summer weather."

The Matter of Wind.
Suppose there are prevailing breezes?"
THE day | won the Deutsch prize in

meters per second at the altitude of the
Eifel tower at the moment | started. And
my present racing airship is very much
faster than my No. g. with which 1 won
the Deutsch prize"
IAN ordinary wind will hardly exist for
it?' L said.
IF l develop a speed of fifty kilometers
per hour with it, / can fulfill the St Louis
conditions in the teeth of a wind blowing
eighteen miles per hour. There you are. 1t
is a question of plus and minus"
Around a triangular course?" ! asked
Il was speaking roughly, to illustrate
the airship's wind condition, which Is ex-
actly like that of a steamboat going up
against the current of a river" replied the
young BriZilian. doubtless the triangle
will complicate the problem; but, remem-
Der, that the wind no matter in what d.
rectton 1t may be blowing any given after
noon, will be very likely indeed to help me
around such a triangle, just much as IL

1 was little far away for hearing his
reply. i cannot be sure about 1t. But l
