The arte of gunnerie. Wherein is set foorth a number of seruiceable secrets, and practical conclusions, belonging to the art of gunnerie, by arithmeticke skill to be accomplished: both pretie, pleasant, and profitable for all such as are professors of the same facultie. / Compiled by Thomas Smith of Barwicke vpon Tweed souldier.

Example.

Suppose a Cannō or Culuering at point blanke shoot 240 paces, and being mounted at one degree outshoote the same 30 paces, what will the sayd peece do being mounted 20 degrees?

By proportion I find, that if at the mount of one de∣gree, any bullet range 30 paces beyond the leuell range, that at 20 degrees if shall outflie the same 600 paces: al∣beit the sayd bullet range not in euery degree a iust like number of paces, yet the proportion will be very neare thereto. And because the peece at the foote of the hill is sayd to be 40 paces further from the Castell, then the like peece planted on the height of the hill, I abate 40 out of 600, rests 560 paces: so farre would the peece in the valley out shoote the other like peece on the hill; so that it must needs follow, her bullet shall pierce so∣rest, for that it hath most strength to flie furthest.
