On the first of January, 1902, ten years after the NorthernRailway locomotives Nos. 2121 and 2122 were put into service,the number of compound locomotives in actual service on theseven principal railroads of France were 1,128 and of the fol-lowing types: — Two locomotives, having two main driving axles not cou-.

It is not, however, to be inferred that thecompound locomotive has made its entire evolution in Franceand has gone through all the stages of its development many another inventor, or initiator, Mr. Mallet was nota propnet in his native land. His example was first followedin foreign countries, especially in Russia, by Messrs. tSorodineand Urquhart, then in England by Messrs. Webb and Wors-dell. But it was in Germany, thanks to the
