By the annexed diagram it will be seen, that if a marble fall from the
hand at A, when it reaches B it has only the quantity of velocity or
force expressed in the angle 1; but when it passes to C, it has the
quantity expressed in the three angles 3; when it passes to D, it has
the quantity expressed in the angle 5; when it passes to E, it has the
quantity expressed by the seven angles marked 7. Thus we may understand
why a tall boy has a better chance at Bonce-Eye than a short one.

It is found by experiment, that a body falling from a height moves at
the rate of 16-1/12 feet in the first second; and acquires a velocity of
twice that, or 32-1/6 feet, in a second. At the end of the next second,
it will have fallen 64-1/3 feet; the space being as the square of the
time. The square of 2 is 4; and 4 times 16-1/12 is 64-1/3; by the same
rule, it will be found, that in the third second it will fall 144-3/4
feet; in the fourth second, 257-1/3; and so on. This is to be
understood, however, as referring to bodies falling where there is no
air. The air has a considerable effect in diminishing their velocity of
descent.

SUN AND THE PLANET TAW.

[Illustration]

This is an entirely new game, and consists of the Sun in the centre,
which may be represented by a bullet, because the sun is the most
ponderous body of the system, and will in this game be required to move
slowly. The planets moving round him, with their satellites, I represent
by marbles. Now, each boy must take the place of a planet; and having
taken it, he is required to put down as many marbles as there are
satellites belonging to it. The boy who plays Mercury, puts down only
one for his planet; the boy who plays Venus does the same; he who plays
the Earth, has to put down one for the Earth, and one for the Moon, its
satellite; the boy who plays Mars puts down Mars and the four satellites
that lie between the orbits of Mars and Jupiter; the boy who plays
Saturn puts down one for the planet, and draws a ring round it, outside
of which he puts the seven satellites in any position he chooses; the
boy who plays the planet Herschel, puts down one for the planet, and six
for the satellites. Each boy, having taken his place in this manner,
lays down his taw on any part of the orbit of his planet he pleases,
being the point from which he must make his first shot.

The rules of the game are
