in fret-work, nothing looks worse to the 
trained eye than the points of angles nip- 
ped off, or left ragged and slovenly done. 
Eepeat this operation at least a dozen 
times, or until you can saw one that has 
all the angles and corners clear and bold. 
When this is accomplished, then attempt 
the cutting of Fig. 14, which is a little

more difficult. To cut this, start the saw 
at A, then run up to the point and a little 
further, then turn the piece around so 
that the saw will take at the point without 
spoiling the sharpness of the angle. The 
other points will require the same treat- 
ment, until B is reached. 
Fig. 15 will perhaps be found more dif- 
ficult at first to cut, than the two previous 
examples; for it is a curious fact, that 
straight lines are more difficult to follow

by the beginner than curved ones; the 
learner, however, should make it a point 
not to lay this example aside, until he can 
follow the lines exactly and leave all the 
angles sharp and clear. 
Fig. 16 shows a series of curves, which 
may be next undertaken. This example

presents no particular difficulty; the 
junction of the curves will require a lit- 
tle care in getting them clear, sharp, and 
uniform. 
Lessons in Magic— IX. 
Fi^esh Laid Egg^. 
THE conjurer orders his assistant to 
bring a plate, which being done, 
he bids him hold it, and then approach- 
ing, taps him gently on the head ; imme- 
diately he opens his mouth and there ap- 
pears an egg. 
The performer takes this out of his 
mouth, puts it on the plate, and then 
passing behind him, goes to his other side, 
taps him again on the head, and another 
egg appears. So he continues until he has 
six or more eggs, which he then prepares 
to hatch. 
Before proceeding further, however, I 
will explain how the eggs are |)roduced. 
When the assistant goes for the plate, 
he puts an egg in his mouth and keeps it 
concealed there; the performer holds 
another egg palmed in his left hand. 
With his right hand he taps his assistant 
on the crown, who then allows the egg to 
appear at his mouth, and when the per- 
former puts his left hand up to take it, it 
is drawn into the mouth again, whilst the 
one in the performer's hand is shown to 
the audience, who suppose it has just been 
taken from the mouth. This egg is laid 
on the plate, which the assistant holds, 
and as the performer passes behind him 
to cross to his other side, he takes a second 
egg from under his waistcoat and con- 
! ceals it in his palm, as he did the first. 
In this way he can take out as many as 
he wants. The last one, however, the 
assistant lets drop from his mouth on to 
the plate, and by this movement sets at 
rest any suspicion that the audience might 
have that the eggs did not come from his 
mouth. 
The Patent Incahator. 
" Now that I have these eggs, ladies and 
gentlemen," the conjurer says, "I will 
show you another very wonderful trick, 
which is no less than my patented method 
of hatching chickens. I will need, how- 
ever, to borrow four or five finger-rings 
from the ladies, which my assistant will 
try to collect." 
The assistant goes amongst the audience 
and requests those ladies who will favor 
him with their rings, to place them on a
