The wheel made bythis company is in no sense an experi-ment, being the logical development ofthe steel tired wheel into one pieceinstead of being in several parts. Thewheel rolling mill used is more powerfulthan any tire mill now in use, and willbe able to roll the hard steel requiredat a uniformly low cherry heat. A peculiar process of heat treatmentfor the forged blank before rolling, A French philosopher, writing aboutthe steam engine, says: Is not inven-tion the poetry of science? All gr
