CHAPTER VIII

OPPORTUNITY KNOCKS

As the young people rose to depart, Professor Gray beckoned Bill and Gus
to remain. He turned to a large table desk, took from it a roll of
papers, untied and laid before the boys a number of neatly executed
plans and sections--all drawn to scale. In an upper corner was
pen-printed the words:

Water Power Electric Plant to be erected for and on the estate of Mr.
James Hooper, Fairview. Engineer and Contractor, J. R. Gray.

"Boys, you see here," began the Professor, "the layout of a job to be
done on the Hooper property. You know I do this sort of thing in a small
way between school terms and I am told to go ahead with this at once.
The amount I am to receive, on my own estimate, is ample, but naturally
not very great; it covers all material, labor and a fair profit.

"But now," he went on, "comes the hitch. I am compelled, by another
matter which is far more important,--having been appointed one of the
consulting engineers on the Great Laurel Valley Power Plant,--to desert

engineer, or a construction firm, it will cost me more than I get out of

Bill looked at Gus and Gus looked at Bill; there was a world of meaning,
of hope and hesitation, in both glances. The Professor saw this, and he
spoke again:

"Out with it, boys! I asked you to stay, in order to hear what you might
say about it. There seems to be only one logical solution. I cannot
afford to spend a lot of my own money and yet I will gladly give all of
my own profits, for I must complete Mr. Hooper's job and look after my
bigger task at once."

"I don't suppose," said Gus, with the natural diffidence he often
experienced in expressing his mind, "that we could help you."

"Why, of course we can, and we will, too," said Bill, th
