Vallel to tlicm at E. The calos being thus fixed, clothe them 

 with leaders, fo that they, with the illuminations and ftw at 

 lop, may all take fire together. 



Illuminated Tew-tree.~Y'\rVi have a tree made of wood, 

 fuch as is fhewn hy fg. 14. The middle piece, or ftem, on 

 which the branches are fixed, muft be eight feet fix inches 

 high : at the bottom of this piece draw a line, at right 

 angles, two feet fix inches long at each fide ; then from L, 

 which is one foot fix inches from the bottom, draw a hne 

 on each fide to C and D ; thefe lines will give the length of 

 the two firft branches. Then put on the two top branches 

 parallel to them at bottom : let the length of each of 

 thefe branches be one foot from the Item : from the ends of 

 thefe two branches draw a line to C and D ; then fix on five 

 more branches at an equal diftance from each other, and 

 their length will be determined by the lines A C and E D. 

 When the branches are fixed, place illuminating port-fires 

 on the top of each, as many as you clioofe : liehind the top 

 of the ftem faften a gerbe, or white fountain, which mull 

 be fired at the beginning of the illuminations on the tree. 



Maon and Seven Stars. — Let^-f . 1 5. be a fmooth circular 

 board, fix feet diameter ; out of the middle of it cut a cir- 

 cular piece twelve or fourteen inches diameter, and over the 

 vacancy put white Perfian filk, on which paint a moon's 

 face ; then let I, I, I, &c. be liars each four or five inches in 

 diameter, cut out with five points, and covered with oiled 

 filk : on the front of the large circular board draw a feven • 

 pointed liar, as large as the circle will allow ; then on the 

 lines which form this ftar bore holes, wherein fix pointed 

 ftars. When this piece is to be fired, it mull be fixed upon 

 the front of a port, on a fpindle, with a wheel of brilliant 

 fire behind the face of the moon ; fo that while the wheel 

 burns, the moon and ftars will appear tranfparent, and when 

 the wheel has burnt out, they will difappear, and the large 

 ftar in front, which is formed of ftars, will begin, being 

 lighted by a pipe of communication from the laft cafe of 

 the vertical wheel, behind the moon : this pipe muft be 

 managed in the fame manner as thofe in regulated pieces. 



Pin IVhcch Firft roll fome paper pipes, about fourteen 



inches long each ; thefe pipes muft not be made thick of 

 paper, two or three rounds of elephant paper being fuf- 

 ticient. When your pipes are thoroughly dried, you muft 

 have made a tin tube, twelve inches long, to fit eafy into 

 the pipes : at one end of this tube fix a fmall conical cup, 

 which do.ne is called a funnel ; then bend one end of one of 

 the pipes, and put the funnel in at the other, as far as it 

 will reach, and fill the cup with compofition ; then draw 

 out the funnel by a little at a time, (baking it up and down, 

 and it will fill the pipe as it comes out. Having filled fome 

 pipes, and made fome fmall blocks, about an inch in dia- 

 meter, and half an inch thick ; round one of thefe blocks 

 wind and pafte a pipe, and to the end of this pipe join an- 

 other ; which mnit be done by twifting the end of one pipe 

 to a point, and putting it into the end of the other, with a 

 little pafte ; in this manner join four or five pipes, winding 

 them one upon the other, fo as to form a fpiral line. Hav- 

 ing wound on your pipes, pafte two flips of paper acrofs 

 them, to hold them together : befides thefe flips of paper 

 the pipes muft be pafted together. 



There is another method of making thefe wheels, called 

 the French, which is, by winding on the pipe without 

 pafte, and fticking them together with fealing wax, at every 

 half-turn ; fo that, when they are fired, the end will fall 

 loofe every time the fire palles the wax ; by which means the 

 circle of fire will be confiderably increafed. The formers 

 for thefe pipes are made from one-half to four-fixteenths of 

 an inch diameter, and the compofition for them as follows ; 



7 



meal powder eight ounces, faltpetre two ounces, and ful- 

 phur one : among thefe ingredients may be mixed a little 

 lleel-filings, or the duft of caft-iron : this compofition fliould 

 be very dry, and not made too fine, or it will ftick in the 

 funnel. Thefe wheels may be fired on a large pin, and held 

 in the hand with fafety. 



Placing Fire-tuorhs to be exhibited, with the Order of 

 Firing. Nothing adds more to the appearance of fire-works, 

 than the placing them properly ; though the manner of 

 placing them chiefly depends on the judgment of the maker. 

 We fliall give fuch rules here, as have been generallyobferved ; 

 for example, whether your works are to be fired on a build- 

 ing, or on ftands. If they are a double fet, place one wheel 

 of a fort on each fide of the building ; and next to each of 

 them, towards the centre, place a fixed piece, then wheels, 

 and fo on, leaving a fufficient diftance between them, for 

 the fire to play from one without burning the other. Hav- 

 ing fixed fome of your works thus in front, place the reft 

 behind them, in the centre of their intervals : the largeft 

 piece, which is generally a regulated or tranfparant piece, 

 muft be placed in the centre of the building, and behind it 

 a fun, which muft always ftand above all the other works : 

 a little before the building, or ftands, place your large 

 gerbcs ; and at the back of the works, fix your maroon 

 batteries, pots des aigrettes, pots des brins, pots des fau- 

 cillons, air-balloons, and flights of rockets : the rocket- 

 ftands may be fixed behind, or any where elfe, fo as not to 

 be in the way of the works. 



Single colleftions are fired on ftands, which ftands are 

 made in the fame manner as theodolite ftands, only the top 

 part muft be long or fhort occafionally : thefe ftands may 

 be fixed up very foon without much trouble. Having given 

 fufficient inftruftions for placing of fire-works, we fttall pro- 

 ceed with the manner of firing them.
