“La Salute e’ in voi!” read the cover, or “Health is in you!” Evidently a toast to the brotherhood for which it was prepared. It was a pamphlet of some sixty pages, measuring about four by eight inches, and cleanly printed in Italian. It was nothing less than a text-book on how to go about making bombs--a sort of guide to anarchist etiquette. It would be unwise to reproduce its instructions here in detail, as they were too accurate for the general peace, but the index which follows will give a conception of the thoroughness with which the anonymous writers in far-off Italy covered their subject. “Index-- First principles 1 Instruments 7 Manipulation 8 Explosive material 11 Powder 14 Nitroglycerine 14 Dynamite 20 Fulminate of mercury 23 Gun cotton 27 Preparation of fuses 31 Capsule and petard 34 Application of explosive materials 35 Bombs 39 Incendiary materials 44” Yes, it was accurate--and very practical. To quote from its advice to struggling anarchists: “We recommend most earnestly that if you wish to engage in this line of work, you procure, before all else, a sufficient amount of money, otherwise you risk being put out in the middle of the street, only to find your long work and trouble all in vain. We recommend at the same time that you do not omit any precaution necessary to avoid attracting the attention of the police, and avoid mixing with the public, nor be seen with known companions. And do not work at it in the house except when necessary.... “The work should be done in a well ventilated room provided with a good chimney place and furnished in such a way that you can hide things if anyone enters, and this room ought to be on the top floor of the house on account of the odors that are always being produced.... “Above all we recommend that you never make explosives for the mere pleasure of making them. All you do beyond enough is useless and stupid--especially so when you have neither the practice nor the proper means for making them. As to the place to keep the dynamite, why make it until it is needed? Take heed that among the various kinds of explosives, bombs, etc., always choose the one that will be most easily used and most practical, remembering always that it is better to do a little thing well than to leave a big thing half done....”
