Pyrotechnics [EPUB ebook] 

Excerpt: "Pyrotechny is possibly the only art which can compete with nature; anyone who has seen a first-class firework display will admit that for impressive grandeur, colour effects, and contrasts of light and shade, pyrotechny is unapproached. That fireworks are popular there is no doubt; no form of amusement is capable of giving enjoyment to so many people at one time; there is no entertainment which so appeals to youth and age of all classes and tastes. And yet it is doubtful if there is an industry concerning which the public at large is so profoundly ignorant."
