steadily from the lie,ffimnng. Besides serving in the instruction of liun- 

 dreds of students, it has supplied the means for conducting- a numl)er of 

 important researches, the results of which have been duly pul)lished and 

 important problems are noAv in process of solution under the patronage 

 of the Carnegie Institution. This, Avhile in terms too brief to be entirely 

 complete, gives a fair picture of the present status of locomotive testing- 

 from a laboratory point of view. 



Just at this time, all who are interested in locomotive design or per- 

 formance have their faces turned to the Louisiana Purchase Exposition. 

 Engineers have always looked upon ji great exposition as serving in many 

 ways to advance the practice of their profession. It has often happened 

 that in addition to the far-reaching influence of their general exhibit, sucji 

 expositions have given occasion for a considerable amount of highly 

 scientific work. At tlie ("entennial Exposition at Philadelphia, in 1S7G, 

 a system of steani-l)oil(>r testing was developed. The Columbian Exposi- 

 tion at Chicago in ISO."', had its engineering congress, and it is of interest 

 to know that the Louisiana I'urcliase p]x])osition at Pt. Louis is to be em- 

 phasized by the working out of extensive iilans foi- locumotive testing. 



It has been announced that the Pennsylvania Railroad Company is 1(v 

 make a locomotive testing iilant the central features of its exliibit at 

 St. Louis, and is to conduct tests uimn loconintives tlirnugliout tlic periol 

 of the Exposition. To this end. it is now installing in the Transportation 

 Building at the Exposition, an elnboi-ale and most l>eautiftilly designed 

 testing plant. The undertaking is being directed by ^Nlr. V. D. Casanave, 

 acting as special agent in charge of the company's exhibit, witli whom the 

 various technical departments of the railroad are co-operating. That the 

 work of testing locomotives may be free from all taint of seltishness, and 

 that it may serve as large a purpose as possible, the company has in- 

 vited the American Society of Mechanical Engineers and the Aiuerican 

 Railway Master Mechanics' Association to have a part in giving direction 

 to its work. Each of these organizations, in accepting the invitation has 

 appointed a committee of three to represent it, which committees, acting 

 together, constitute what is now known as the Advisory Committee of 

 the Pennsylvania Company for Locomotive Testing. The writer's connec- 

 tion with the work is that of a member of the Advisory Committee. 



It has lieen planned to test twelve locomotives, a number of which 

 will be of foreign manufacture. One is to be a de Glehn balanced emu- 

 pound, which has lieen ordered by the Pennsylvania Company and will
