Which ia the Strontrer in Hroportlon to Weight- A Simple nil IntercstiiiK Experiment. The relatlve weights of wood and steol In proportion to their strength is :i matter whi'li probably nol tme oui of one hundred reailcrs cvi't had oeeasfon t" lnveiaat. If the conundrum were propoutided : "Wbich ia il"1 utroagfT - Wood nr Steel?" mnety-nine out oi a hundred woiud be likeJy to answer thal steel possessea greater strength in proportion to weight thari does wochI.

We are indebtod to UeaBIS. Anltman, Miller t Co., of Akron, Ohio, for the accompanying illustration. It was the picasure of a representativo of t Iris paper, while in I Akron a few days sincc, to witness this experiment. A piece of ash, sucli as is used . En the Buckeye machine, was placed in a clamii aloiií? with a piere of steel of ciim1 length, the saino as is iihI in all steel Hin1 ders. The steel weighed jnsi twice as matk tus tint vrood; :unl vet the steel invariahly viel. led and bent as the pri'ssure waa hrnuglit down.
