and fire them; when if they leave a black and sooty mark behind them,
with a noisom smell, and sindg the Paper, then is that Powder gross and
earthy, and will fail your Expectation, if you use it in your

fastened to the _Dragons_ Tail; so that as you turn that Wheel, they
will run furiously at each other, and as you please you may make them
retreat and meet again, Soaping the Line to make them slip the easier;
