Of the unfinished rail before It passes through the fin-ishing roll, the product is brought up to the standardof hardness which the railroads are now the new process, as conducted at the Edgar Thom-son mills, the rails are allowed to cool from thirty toforty seconds before being passed through the thirdor finishing set of rolls. This is accomplished bymeans of a cooling table which Is so arranged that itdoes not interfere with operations, the roughing of therails proceeding while the cooling is going on. Underthe new arrangement the unfinished rails are shovedout under the rolls onto the cooling table, with thehead of the hot rail placed next to that of the onewhich preceded it. Being thus placed, the flange,which is thinner, cools at about the same temperature as the head, the heat be-ing equalized so that theflange Is not In a differentcondition from the thickhead In the final rolling. It is generally concededthat this Invention is oneof the most Important dis-coveries
