The aeroplanes were readjusted
and then for an hour the craft sped on untouched. At eight o'clock
Ned said:
"We haven't traveled over eighteen miles in an hour and we've been
afloat four hours. If we are still over the Chusco and Elmer and
Buck are at the appointed place we may be within ten or twelve miles
of them."
"They are going to burn three small camp fires set in a triangle,
you remember," remarked Bob.
"Therefore," suggested. Ned, "all keep a sharp lookout."
At half past eight Ned showed some concern. No lights had been
sighted and the reckoning showed that they must be within two or
three miles of the probable location of the camp. Another fifteen
minutes went by, and yet no signal fires were seen. They had now
passed over the junction of the two rivers, if their calculations
were right, and Ned and Alan were in a quandary.
"It's no use to go on," commented Ned; "so we'll just make a wide
circle and see what we can find."
It was also useless to look below. In the darkness there was no
sight of either river or desert.
"It we don't pick them up in that way," continued Ned, "we'll
descend and tie up for the night.
