Last month the fact that the Brooks Locomotive Works hadreceived the order for four locomotives for the Seoul-ChemulpoRailway in Korea was noted, these locomotives have been com-pleted and one of them is illustrated by the accompanyingcut. Last year an American firm secured from the Royal Gov-ernment of Korea a concession to build a railroad, the firstand only one in that country, and notwithstanding constantpolitical disturbances its construction and equipment havegone steadily forward. This railroad is of the American stand-ard gauge (4 feet S/z inches) and is known as the Seoul-Che-mulpo Railway extending from Seoul, the capital of Korea, onthe north to Chemulpo, the chief seaport on the south, a dis-tance of about 25 Books Locomotives for Korea. conditions as regards forging stresses are stated in the paperas follows: In our judgment, the real reason for the prejudice againststeel, and for the alleged mysterious fractures occasionallynoted, is due to the unequal strains set up in the materialcaused by unequal heating and working. In the process offorging we are putting work upon the piece, and, if this is so,no two blows are given under the same conditions. The metalis cooling slightly between each blow, so that it can be safelysaid no two parts have been worked alike, and the material inthis form has forging strains in it. In other words, there is adifferent condition for every inch of length of the forging, con-sequently we maintain that there is just as much a necessityfor relieving these forging strains as there is for relieving thestrains in a complicatedly flanged throat sheet of a boiler byannealing. That is to say, the throat sheet, after flanging
