side himself with despair; and
determined on doing something, he seized the two Eds, and extracting
from their pockets every torpedo he could find, flung the latter, in the
heat of his passion, out of the window, which naturally resulted in a
report much louder than the first one, and thus materially quickened the
pace of the poor, bewildered animals.

And now a new danger arose. What if they should catch up to the car
ahead?

But, luckily for all concerned, the stables of the company were not far
off, and when the horses reached the car-house they slowed up, and the
Roverings were rescued.

"But why didn't you put on the brake?" asked the superintendent.

Sure enough, why hadn't they?

HOW TO BUILD A STEAM-YACHT.

Most of you boys know enough about boats to have built your sloop and
schooner yacht, and perhaps a canoe; now why not go a little farther,
and build a steam-yacht? Don't worry about your engine, boiler, and
propeller; these can be bought complete at a low figure--an engine that
will reverse, stop, and send your boat ahead at the rate of two miles an
hour.

After taking a good look at the plates, and having made up your mind
that you are equal to the task, go and see your friend the carpenter,
and tell him you want a piece of white pine, free of knots, grain
running lengthwise, well seasoned, thirty inches long, seven wide, and
six deep. I speak of white pine, for the reason that it is easy to get,
inexpensive, and cuts easily. Plane the four sides smooth; mark a centre
line, AB, on both top and bottom.

[Illustration: PLATE I.]

[Illustration: PLATE II.]

The centre of your block must now be marked at right angles to the line
AB on top and bottom; carry this line down the sides as well. This is
the line marked X in Plates I. and II. Now for the first cutting of the
block--the sheer line SH on Plate I. The dotted lines marked from 1 to
10 must be drawn, beginning at 1, just one inch from the left-hand end
of block, No. 2 three inches from this, and so on, 3, 4, 5, 6, 7, 8, 9,
10; the last number will be just two inches from the right-hand end.
These are to be marked on top and on both sides. These lines are very
important, as the shape of your boat depends upon them. With a pair of
compasses take distances from the line AB, Plate I., at numbers 1 to 10
respectively, to the line marked SH, and join the points with a
straight-edge. This is your sheer. Work from the bow to about the centre
