430 THE CENTURY, 



30. 



A way in one nights time to raife 

 a Bulwork twenty or thirty foot 

 high, Cannon-proof, and Cannon 

 mounted upon it, with men to over 

 look, command and batter a Towne ; 

 for though it contain but four Pieces, 

 they fhall be able to difcharge two 

 hundred Bullets each hour. 



[A Rising Bulwork.~\ Grose, in his &quot; Military Anti 

 quities,&quot; Vol. I. page 385, notices a moveable tower, 

 the use of which was revived by the Eoyalists in their 

 attack on Gloucester, during the Civil War. 



In 1644, Edmond Felton, gentleman, published a 

 pamphlet entitled, &quot; Engins invented to save blood and 

 moneys ;&quot; the nature of which he &quot; discovered unto 

 the Committee for the fortifications of the City of 

 London.&quot; The Honourable Major General Skippon 

 attested in respect of it, that the engine &quot; was of three 

 tiers often muskets in a tier, to shoot arrows withal.&quot; 

 The inventor satisfied the Committee, &quot; how an engine 

 will secure the foot from the horse, and the soldiers 

 from musket shot, which engine in fair ways two men 

 may manage at pleasure.&quot; 



He complains of a piracy of his invention, observing, 

 &quot; There was about twenty of the said engines made at 

 Oxford, and from thence carried to Gloucester, to go 

 up to the walls. And had not his Excellency the Earl 

 of Essex so happily arrived to raise the siege as he did, 

 it was reported by some of the army, the city was in 

 great fear to be taken thereby ; most of which said 

 engines the besiegers burnt, because they should not be 

 taken.&quot;
