SUppose a Generall having approached to a certain Hornwork which is here decyfered by the Letter H. and hath come with his line or fapp near unto the moat of this Horne∣work, and there desires to cast up a royall battery in the place noted A. for to flanck upon E. D. and D. C. in such sort, that the force of the Canon may beat aswell upon the Face as upon the I lanck, to wit, Proportio Equalis, by an equall proportion. Together that the two wings C. D. and G. I. and the distance G. D. which are all alike to each other, may be flancked with the lines and blowes, yet so, as the distance of the battery A. to the point C. be no more then sixty Rodd or six hundred foot, and the breadth of the Hom-work to be as M. N. or O. P. and being measured, is found to be 34. Rodd, 7. foot, and 4. Inches. The question is how this must be wrought.
Moreover of the same Hom-work the face is as much as the two greatest valuation of 1. a. there a. 1. aaaaaaaa. 875. aaaaa. 3470. aaaa. 20640. aa. 104040. a. are alike to 5. aa aaaaa. 1147. aaaaaa. 28182. aaa. 118800. and the distance A. C. no surther then 900. foot. O. A. and the rest of the conditions as abovesaid. The question is to find out the breadth of the Horne-work, and also the other parts as is abovesaid.
