Thomas Baines, Shifts and Expedients of Camp Life…
“ Almost any old gun or musket, provided that it will go off when the trigger is pulled, and will not burst from the effects of a good heavy charge, will answer the purpose. The most convenient form of gun trap we have ever used is formed by lashing a piece of horn, bone, or polished wood, to the back of the trigger guard with waxed thread, as shown in the annexed illustration. The trigger string is then brought back, passed through behind it, and led forward through the ramrod hoops. The gun, when heavily loaded, is lashed fast to some tree or post at a convenient height from the ground. ”
