Formulas and test data relating to wooden and iron pit props, considering advantages and disadvantages of each type; results of tests on two new iron props by Stephan, Frohlich and Klupfel; iron prop is claimed to be cheaper than timber props, and is capable of carrying heavier load, with less risk of buckling; concludes that advantages of iron props exceed disadvantages.
