the manufacture of explosives. As the greater number of these 

 plants are now working on con- 'Her time than lias 



the case before in years, and as new plants have rt 

 Keen established, it would be safe to add about I ent. t" 



the number oi workmei in this sort of manufacture. 



■ i it wi mid hardly be an 

 tion to say that 10.000 men arc now engaged in making explo- 

 sives ui the American powdei I tories "> private ownership. 

 'I., this number should lie added I.(KK) m 1.J00 nun engaged in 

 the government [dams, making not far from 12,000 workmen em- 

 ed in American powder mills i i oni sort or another. \"ol 

 all these men are compelled to protect themselves in a r 



iment, but all who arc employed in the initial 

 converting cotton into an explosive substance where nun. 

 is used — arc compelled to wear gloves and aprons and 

 made of rubber. 



And this does not take into account at all the large number 

 of workmen engaged in the factories that produce nitrii 

 sulphuric acid. I"he necessity they are under of wearing com- 

 plete rubber pr< tection is even greater. But the ordinary r I 

 boots, gloves and aprons meant for general service are not 

 immune to the action of strong acids, so that it is necessary to 

 make the rubber equipment worn by workers in acid and po' 

 mills of a special compound with particular reference to the 

 trying conditions under which it is to be used
