Subparagraph A. Reference to your telegram 253, recommend filling approximately 10 per cent all shells with gases as given below, but that filling plants and gas factories be made capable of filling a total of 25 per cent. Unless ordinary name is given, gases are designated by numbers in chemical code War Gas investigations. Of 75 millimeter shells fill 1 per cent Vincennite, 4 per cent phosgene or trichloromethyl chloroformate, 2 per cent chloropicrin, 2½ per cent mustard gas, ½ per cent with bromoacetone and ½ per cent with smoke material. According to French 75 millimeter steel shells should not be filled with Vincennite more than three months before being used. No trouble with other gases or other sized shells except that bromoacetone must be in glass lined shells. Of 4.7 inch shells fill 5 per cent with phosgene or trichloromethyl chloroformate, 2 per cent with chloropicrin, 2½ per cent with mustard gas, ½ per cent with bromoacetone and ½ per cent with smoke material. Provide same percentage for all other shells up to and including 8 inch caliber as for 4.7 inch shells. 4 inch Stokes’ mortar will use same gases and smoke shells and in addition thermit. 8 inch projector bombs will use the same as the Stokes’ mortar and also oil to break into flame on _bursting_. Cloud gas cylinders will be filled with 50 or 60 per cent phosgene, mixed with 40 to 50 per cent chlorine, or phosgene and some other gas. Renew recommendation that filling plants be established in France to provide sudden shifts in gas warfare of all kinds, as well as for filling all 4 inch Stokes’ mortar bombs, 8 inch projector bombs and cloud gas cylinders. It is strongly recommended that efforts be made to produce white phosphorus on large scale for its usefulness both as smoke screens and to produce casualties. Subparagraph B. For the Adjutant General of the Army. With reference to paragraph 2, my cablegram 181, desire information as to whether recommendation is approved that an engineer officer assisted by Professor Hulett be assigned to Gas Service in Washington to handle all orders and correspondence concerning gas. Subparagraph C. For Surgeon General. With reference to paragraph 2 your cablegram 205, and paragraph 2, my cablegram 181, what is status of chemical laboratory for France? Also have the 12 selected Reserve Officers for training in gas defense sailed for France?
