WATER ROCKETS. 



convoy it to (he other end ; and this end being then kindled, the 

 rocket will move backwards, and return to the place from which 

 it Ml out. 



Two rockets of equal size, bound together by means of a piece 

 of strong pack-thread, and disposed in such a manner that the head 

 of the one shall be opposite to the neck of the other, that when the 

 fire has consumed the composition in the one, it may be communi. 

 cated to that in the other, and oblige both of them to move iu a re. 

 trograde direction, may also be adjusted to the rope by means of a 

 piece of hollow reed. But to prevent the fire of the former from 

 being communicated to the second too soou, they ought to be co- 

 vered with oil-cloth, or to be wrapped up in paper, 



REMARK. 



Rockets of this kind are generally employed for setting fire to 

 various other pieces when large fireworks are exhibited j and to 

 render them more agreeable, they are made in the form of different 

 animals, such as serpents, dragons, &c. ; on which account they 

 are cattcdjlying dragons. These dragons are very amu>ing, espe. 

 cially when filled with various compositions, such as golden rain, 

 long hair, &c. They might be made to discharge serpents from 

 their moutlis, which would produce a very pleasing effect, and give 

 them a greater resemblance to a dragon. 



SECTION II. 



Rockets zshtch Jly along a Rope, and turn round at the same 



time. 



NOTHING is easier than to give to a rocket of this kind a rotary 

 motion around the rope along which it advances; it will be- sufii. 

 cient for this purpose, to tie it to another rocket, placed in a trans* 

 versal direction. But the aperture of the latter, instead of being 

 at the bottom, ought to be in the side, near one of the ends. If 

 both rockets be fired at the same time, the latter will make the 

 other revolve* around the rope, while it advances along it. 



SECTION III. 



Of Rockets zohich burn in the Water. 



THOUGH fire and water are two things of a very opposite nature, 

 tne rockets above described, when set on fire, will burn and pro.
