THE OPENING FOR RUBBER EXPERTS. 



M OT a few letters reach us from time to time inquiring 

 about the outlook in the India-rubber industry for 

 a young man of technical training. Such a letter is now 

 before us, the writer of which, having become much inter- 

 ested in rubber in the course of his studies in a scientific 

 school, is moved to ask " if there is any field for rubber 

 experts ? " We assume that his inquiry relates to the rub- 

 ber factory, and shall venture to answer accordingly, 

 though scientific work is beginning to be called for in the 

 production of rubber no less than in the manufacture of 

 rubber goods. 



The opportunities in rubber factories for technically 

 trained men are doubtless increasing, owing to the fact 

 that rubber manufacturers, in common with all others, are 

 coming to realize more fully the advantages of modern 

 scientific methods of systematic study of the conditions and 

 problems connected with their industry. The single fact 

 that the leading railway companies now demand that their 

 more important supplies of rubber goods shall conform to 

 definitely specified requirements in construction and qual- 

 ity, has a far reaching significance and influence with the 1 

 manufacturers. They are awaking in general to the value 

 of the scientific method, and are gradually dropping anti- 

 quated machinery and processes and even relaxing the 

 traditional secrecy that has so long hampered progress in 

 the rubber industry. 



The man with a technical education has ample oppor- 

 tunities in many industries, and generally in proportion to 

 the magnitude of the industry. The financial success of 

 the Standard Oil Co., for example, has been due to noth- 

 ing else so much as to the expert scientific work which the 

 directors of that great corporation have been wise enough 

 to employ, in utilizing to the utmost every constituent of 

 their raw material, and at a minimum cost, so as to place 

 the products within the reach of the greatest possible 

 number of buyers. And the great prominence of the steel 

 industry is a direct result of chemical science. The rub- 

 ber industry is especially inviting to the chemist or chemi- 

 cal engineer, and while the total volume of the industry 

 must ever remain small in comparison with some others, 

 and the possible financial reward of the scientific worker 

 may not be so great, there must always be desirable posi- 

 tions open for expert work of the right kind. Successful 

 competition in the rubber industry, as in every other, de- 

 mands a scientific knowledge of the possibilities of the 

 materials employed and thorough study of the economics 

 of manufacture. This means the devotion of somebody to 

 the mastery of these details and, in the end, advantage to 

 the company employing him. The crowded scientific 

 schools of the United States — not to mention those else- 

 where — and the wide extending clientele of the corre- 

 spondence schools, attest the extensive development of an 

 influence which is to react on the industries of the nation 

 and, through the work of trained men, modernize and ad- 

 vance the methods of manufacture in every line. 



The literature of India-rubber, of comparatively recent 

 origin, is rapidly growing in volume and becoming more
