And we ſhall find, that if they are well rubb'd
<
lb

and poliſhed, they will defy the Fury of the
<
lb

Weather. </
s

<
s
>The ſame is true of Stones that are
<
lb
/>
poliſhed, which thereby eſcape being eaten
<
lb
/>
with Ruſt. </
s
>
<
s
>And it is thought that Bricks
<
lb
/>
ſhould be rubbed and ground either immedi
<
lb
/>
ately upon their being taken out of the Kiln,
<
lb
/>
before they are wetted; or when they have
<
lb
/>
been wetted, before they are dry again; be
<
lb
/>
cauſe when once they have been wetted and
<
lb
/>
afterwards dryed, they grow ſo hard that they
<
lb
/>
will turn and break the Edge of the Tool;
<
lb

but they are eaſier to grind when they are new,
<
lb
/>
and hardly cold. </

<
s
>There were three Sorts of

lb

Bricks among the Ancients; the Firſt was a

Foot and an Half Long, and a Foot Bread, the

Second fifteen Inches every Way, the Third a

Foot. </

<
s

<

the Ancients did not uſe the ſame Sort of Brick
<

in their publick as in their private Edifices. </

<
s

have obſerved in ſeveral of their Structures, and

particularly in the

Way, ſeveral dif
<
lb

ferent Sorts of Bricks, ſome bigger, ſome ſmall

er; ſo that I ſuppoſe they uſed them indiffe
<
lb

rently, and put in Practice not only what was
<
lb
/>
abſolutely neceſſary for Uſe, but any Thing
<
lb
/>
that came into their Fancy, or which they
<
lb
/>
thought would conduce to the Beauty of the
<
lb

Work. </
s

<
s
>But, not to mention others, I have
<
lb
/>
ſeen ſome not longer than ſix Inches, and not
<
lb
/>
thicker than one, nor broader than three; but
<
lb
/>
theſe they chiefly uſed in their Pavements,
<
lb

<

n

<
lb

where they were laid edgeways. </
s
>
<
s
>I am beſt
<
lb
/>
pleaſed with their triangular ones, which they
<
lb
/>
made in this Manner; they made one large
<
lb
/>
Brick, a Foot Square, and an Inch and an
<
lb
/>
Half Thick; and while it was freſh they cut
<
lb
/>
it in two Lines croſſways from one Angle to
<
lb
/>
the other, which divided it into four equal
<
lb
/>
Triangles. </
s
>
<
s
>Theſe Bricks had the follow
<
lb
/>
ing Advantages, they took up leſs Clay, they
<
lb
/>
were eaſier to diſpoſe in the Kiln and to take
<
lb
/>
out again, they were more convenient for
<
lb
/>
working, becauſe the Bricklayer could hold
<
lb
/>
four of them in one Hand, and with a ſmail
<
lb
/>
Stroke divide the one ſrom the other; when
<
lb
/>
placed in the Wall, with their Fronts ſoremoſt
<
lb
/>
and their Angles inward, they appeared like
<
lb
/>
compleat Bricks of a Foot Long: This made
<
lb
/>
the Expence leſs, the Work more graceful, and
<
lb
/>
the Wall ſtronger; for as there ſeemed to be
<
lb
/>
none but entire Bricks in the Wall, the Angles
<
lb
/>
being ſet like Teeth in the Rubbiſh that was
<
lb
/>
laid in the Middle, made it extremely ſtrong
<
lb
/>
and durable. </
s
>
<
s
>After the Bricks are moulded,
<
lb
/>
they direct that they ſhould not be put into the
<
lb
/>
Kiln till they are perfectly dry, and they ſay
<
lb
/>
they never are ſo under two Years; and they
<
lb
/>
are reckoned to dry better in the Shade than in
<
lb
/>
the Sun: But of theſe too enough, unleſs we
<
lb

will add that in all this Sort of Works, which
<
lb

are called Plaſtick, they reckon excellent,

among others, the Earth that is called
