ps I have seen are made in the same way
as the sailing vessels."

"That is exactly what I inferred in my answer to your first question.
The truth is, that in experiments which have been made, it is shown that
to have the widest part of a steamer near the stern, gives lines to a
hull which has less resistance than if made in the conventional way."

"I thought probably the reason for making them so was just the same as
in the case of an arrow, where the heaviest part is at the forward end."

"In that case an entirely different principle is involved. A body falls,
or is projected through the air, with its heaviest end foremost, because
of the greater momentum in that portion."

"It is the force of a body in motion. When a body is projected through
the air it meets with the resistance of the atmosphere, and this also
serves to turn the heavy side around to the forward end, because the
force of momentum in the heavy end is much less affected by the
resistance of the air than the lighter end." (See Fig. 5.)

Red Angel had now been with them more than six months, and he was
probably a year old. When first captured he was a scrawny infant, dull
and stupid, like all of his class. He had wonderful powers in the way of
imitating habits and customs. The boys were very good vocalists, and
while at work Harry would sing, but George whistled. It was an amusing
sight to watch Red Angel when the boys engaged in the frequent concerts
at night.

But of all the screamingly funny exhibitions, the attempt of Angel to
imitate whistling was the most ludicrous. The orang's lips project too
much to a point, and the jaws are so narrowed that the lips will not
pucker. Whenever the boys commenced their concert Angel would be on
hand, and enjoyed every moment of the time, and the boys had many a
concert purely for his benefit.

At the end of each concert the whistling would begin. This invariably
brought Angel to the front, and his exhibitions would be given with the
utmost gravity and earnestness. The invariable result would be such
uproarious fits of laughter on the part of all that he would take part
in the jollification, little suspecting that the laughter was at his
expense.

The only sound which he could emit during these performances sounded
like a high-pitched stick rattling along a pale fence; but he was
inordinately proud of it. It had always been on one key, here
