Note 1 — Value of Corcuera’s Seizures in Jolo

Camaras were tubes or cylinders which received the charge and were introduced into the breech of the cannon, sometimes fitted by pressure, at other times by screwing (see Diego Ufano’s Treatise on military; Brussels, 1617). Some of the ancient pieces of ordnance had these spare chambers, so that, after a charge had been fired, the chamber could be changed and operations carried on more rapidly. Thus they served as do the cartridges of modern breech-loading guns. Some camaras were used independently of the cannon, for firing salutes. See Stanley’s Vasco da Gama (Hakluyt Society publications, London, 1869) pp. 226, 227, note.
