pastlng slips OF paper along their edges anu
those of THE flat bottom. He cut from the
anne pastebOhrd a series of four braces
like those represented IN A, b, e, ID, on
the left OF fig. l which he placed across
the bottom al the places indicated in fig
I /, between the strips OF pasteboard that
formed the sides OF the boat. The result
was very fair looking hull for flat
bottomedboat, a good model, and one whose
SIDES exactly reOrresponded This, had
he tarred or painted 1t, would have been In
a measure watrr tight, and would on the
whole, have made a pretty good boat, but
Tom did not stop here. This was but the
mold on which the boat was to be built
USING THE CLAY.
This mold he flied with clay and sand
mixed tp!aster. of paris would have been
better, but he had none,, and left it in the
sun to bake andSfsasden. After t.:s, when
the clay inside was firm and dry, he care
fully removed the odrsfde pasteboard, leav-
ing the braces imbedded in the mold. The
process did not separate the clay into sec
tions, so that-aon taxing the remaining
pasteboarG away the clay fell apart, DO
cause the clay inside the boat rested upon
and was a part of the large lump OF clay
forming sort or support OF pc lestal upon
which the eiay-filled hull rested, the paste
board sides and bottom removed. Tom set
in the clay astrip of sheet lead he procured
from the village store. 1t was part of the
lining of a tea box, and doubled IT was just
about the thickness for the boats keel, for
which he designed it. 1t may properly to
remarked here that the keel formed as
shown in figs. . and 3 is of use in making
or the pasteboard mold itself a boat. which
can easily be done by giving 1T two coats
OF white lead to make ii waterproof. and
setting the lead in between the double sides
of the keel.
To proceed, however with the paste
boat. Tom first applied stiff cCst OF
common flour paste all over the clay
model, winch he then covered with mus
lin, LAYING 1t -anaover the leadcn keel and
all carefully and smoothly. This, when
DIS. was thoroughly brushed over with
shellac varDish, which, in turn, was al
lowed to dry and then painted with white
lead oil color such as house painters u.s.,
any sort OF oil paint would do. sup
pose. While the paint was still sticky
Tom laid over all thickness OF common
wrapping paper. This, in turn, was
treated with varDish and paint and an
other layer of wrapping paper added.
The sides and bottom were now stiff ard
strong enough. All that remained to re
done was to dig and wash away the dry
clay and sand inside. This done, it iE
really surprising how firm and strong
the materials of which the little boat
was constructed proved to be. The
braces had insured the symmetry and
similarity of the two sides, and the
thinness of the sides and bottom after
they had been well sandpapered seemed
little less than that of an egg shell

There was only one trouble. 1t was flat
boLtomed. Afterward, however. by sim
ply pasting strips of pastetoard together
OH three sides and forcing between them
braces OF the required shapes at proper dis
tances apart, a S shown in Zig. /, we OBJ
tanned better models. Sometimes we had
to dampeD the pasteboard and pack clay
around outside as well az inside 1T to make
the stiff pa steboard take the curves of the
braces, but. generally speaking, this was
unnecessary.
The advantages OF pa ste boats are their
lightness, for their sides can Re made as
thin as egg shells, their toughness, the
case with which any child of ordinary
constructive ability can make them, and
the iDexpeDslveness of the materials and
tools required In their manufacture. 1t Is
