When a pupil is instructed in "standing on sills" he does exactly as the term implies, but on the inside of the building is his mate, who holds him in place by means of this belt-hook. In such position he raises the ladder to the window above, as when he was astride the sill.
Another lesson, which Seth often took, is that of coming down a rope alone, or bearing a burden. It was not difficult, and, with this particular "probationer," decidedly exhilarating.
A rope is made fast to the roof or window, of a building and two turns of it taken round the hook on the fireman's belt, thus forming a "brake" to prevent too rapid descent. By a pressure of the hand just below the hook it is possible for the operator to control his speed. In case of bringing down a burden, twice the number of turns are taken.
As a matter of course, Seth was taught to leap from the building into a net, and later to aid in holding it, in which last exercise he learned that 'Lish Davis had not spoken falsely when he declared it was exceedingly hard work.
It might not be entertaining to repeat all the lessons which Ninety-four's kid took part in; but suffice it to say that by the 1st of May Mr. Fernald announced that he was as nearly perfect in the drill as he could be until after having gained greater strength.
"You will participate in the exhibition, my boy, and I am expecting a good showing from you."
"Will Ninety-four's men be there?" Seth asked eagerly, trying hard not to show how delighted he was by this praise.
"Surely; they are to take part in the parade, and you can see 'Lish Davis display his skill at driving. There are no lack of spectators at such exhibitions, and you will show, not only to a vast throng of citizens, but the mayor and heads of the Department, whether you are worthy of receiving an appointment."
"Will that settle matters for me?" Seth asked in surprise.
"I don't say you will not be able to get the appointment without it; but it is an opportunity of making a leap directly into the Department, and of finding yourself suddenly on equal footing with Davis, Walters, or Black, for they are intending to make a strong effort to have you assigned to their company."
