An amusing incident occurred recently in a factory where a large lifting

magnet is used in connection with a crane to carry pig iron through the

shop. Just as the operator was bringing it across the shop unloaded, he

saw two laborers ahead of him in altercation. One held a short pinch bar

and the other a heavy shovel. As he approached, they both raised their

tools like weapons. In a flash the operator switched on the current and

the two men stood as if transfixed, hanging desperately to their weapons

that were held aloft as by some giant’s hand. The laughter of everyone

who saw the tableau ended the quarrel.

Why is the Thistle the Emblem of Scotland?

According to tradition, the Danes were attempting to surprise an

encampment of the Scotch one night, and had come very near to it without

being observed, when a Dane stepped on a thistle and its sharp points

made him cry out with pain. The Scotch were then awakened and succeeded

in defeating their assailants. Ever since that time the thistle has been

made the insignia of Scotland.

How are Animals Identified on Cattle Ranges?

The question of how to mark animals started with the first stock

raisers. In those days the main object was to provide some way animals

could be identified as to ownerships, and many crude and more or less

cruel methods were used, such as notching or lopping off part of the ear

or branding with a hot iron, burning a letter or figure often ten or

twelve inches high on the side of an animal. Branding in this way was

used mostly by cattle raisers when large herds were grazed on the

western plains. The large brand made it possible for cowboys on

horseback to separate the cattle of different owners, as the brand could

be seen at some distance.
