Today the Colt Company manufacture revolvers in which the simultaneous ejection of the cartridge-cases and recharging of the chambers is combined with a strong, jointless frame; automatic magazine pistols in which the pressure of the powder gases, as above said, is utilized after giving the proper velocity to the projectile, it requiring only a slight continued pressure on the trigger for each shot; automatic machine guns firing at will single shots or volleys while requiring only a slight pull upon the trigger; and the improved manually-operated Gatling gun firing the improved modern ammunition. The cartridges are carried on a tape which feeds them with the necessary rapidity into the barrel. What would be the history of the European War without the machine gun is not easy to state, but as a highly efficient weapon of war its quality has been abundantly proved. * * * * * How does the Poisonous Tarantula Live? When the National Guardsmen from all over the Union were concentrated along the Mexican border, many reports were sent home of thrilling experiences with tarantulas, to whose bite the natives of Mexico, Italy and many other warmer countries have ascribed a disease called “tarantism.” The Italian peasants believe that this disease can only be cured by a certain kind of music. The tarantula, like many other members of the spider family, is an expert in the making of burrows. Its burrows are artfully planned. At first there is a sheer descent four or five inches in depth, but at that distance below the surface the tunnel turns aside before dipping straight down again to its termination. It is at the angle or elbow of the tunnel that the tarantula watches for the approach of enemies or prey, like a vigilant sentinel, never for a moment off its guard, lying hidden during the day, if nothing disturbs it, and coming out at nightfall to seek its prey. Unlike most other spiders, it hunts its game without the aid of webs or snares. It does, however, possess the ability to spin the silk which we have all seen other spiders make, for, in digging its hole, it makes neat little packages of the dirt it has scraped up, bound together with silk and slime from its mouth, and flips them to one side out of the way. When it comes to hunting, it makes sure that it can pounce on its prey, by building the entrance of its hole about two inches in diameter and up from the surface an inch or so, so that it can spread its legs for the leap.
