city with sixty-two fellowships, covering a wide variety of 
different problems. These fellowships employ one hundred 
and ten research chemists and engineers. The continued 
financial support of the Messrs. Mellon has made it possible 
to develop the system to its present strong position. 
By the application of the Industrial fellowship system, 
the Institute has been successful in demonstrating to Ameri- 
can manufacturers, irrespective of size, that industrial re- 
search, properly carried out, is profitable to them. Most of 
the problems accepted for study, 1911-1928, have been 
A Corner in the Machine Shop of Mellon Institute 
solved satisfactorily, and many chemists and chemical engi- 
neers have been trained in research methods and then placed 
in useful industrial positions. The Institute has also been 
active in stimulating research in other laboratories and in 
cooperating with other research establishments, both in the 
United States and abroad. It is however best known by the 
successful commercial processes which it has developed and 
by its contributions to the literature of chemistry and allied 
sciences. The total contributions to literature for the fifteen 
years ended January 1, 1927, were as follows: 12 books, 
56 bulletins, 411 research reports, 636 other articles, and 322 
United States patents.
