be, glewing the Paste-board between each Rowling; then being about five
Inches thick, bind over it strong pitch'd Rope, though indifferent
small: Then choak the Breech of it, which must be beyond the length of
the Rowler, with a strong Cord; pitch or glue it over that the Powder
may not force its vent that way, and so when the Mortar is well dry'd,
draw out the Rowler, and make it as even as can be; bore a Touch-hole
two Inches from the Breech, that it may enter into the hollow of the
Mortar, and set it by for use.


_To make Balloons, the rarity of Fire-works._

Take strong Paper, or Paste-board, rowl it on a 12 Inch Rowler, near as
thick as 'tis long, then with a strong small Cord choke it at one end
only, leaving a Port-fire, which is a place to put in a Quill of
Wild-fire, that will last till being shot out of the Mortar it comes to
its height; then next to that put on an Ounce and a half of loose
Powder, and place in it as many small Rockets and Stars as it will hold;
so choak up the other end quite. You may also put into it little quills
of Wild-fire, then being closed up, only a Port-fire remaining, which
made of a Quill of Wild-fire, as is said, or Stopple, to make which in
the close of this Head I shall Instruct you, Charge the Mortar, being
set Sloaping upwards with half a Pound of corn Powder, and it will by
giving fire at the priming holes, send the Balloon up into the Air a
prodigeous height, and when it comes to the dry Powder, that will break
the Balloon; and then the Stars and Rockets in it taking fire, will
scatter abroad in various curious Figures delightful to the Spectators;
and as they are Cunningly placed, they will represent Crowns, Cyphers,
Characters, Dates of the Year, _&c._
