The only type of shell filled was the 75 mm. variety, because either the shell of the other sizes or the accompanying boosters (bursting charges) were not available. The work done by the filling plant is shown by the following figures, representing the number of shell, grenades, etc. _75 mm.

The number of casualties should change the mind of anyone who feels that men chose this work as being “safe” instead of going to France. During the six months from June to December there were 925 casualties, of which three were fatal, two being due to phosgene and one to mustard gas. These were divided among the different gases as follows: Mustard gas 674 Stannic chloride 50 Phosgene 50 Chloropicrin 44 Chlorine 62 Other material 45
