so that we would know what it is like. This without helmets. Then with three officers, one before, one in the middle, and one behind our string of six nurses, and a medical officer standing outside, we were taken into a closed, tunnel-like affair into which chlorine gas was being poured in clouds from special pipes. We of course had our masks on and were all carefully inspected before we went in. This gas would not hurt us, they say, but we get the smell and get used to wearing the masks and are ready afterwards to get our certificate. August 20, 1917. The last letter I wrote was August 8th and here it is the 20th. The time goes so very rapidly I forget when I last wrote and am surprised to find that it is over a week. We have not been so very busy these past two weeks, I mean not as we were before then. It has not been raining as much these past few days, to our great relief, and we are beginning to get dried out a bit. When mattresses begin to get moldy inside of huts, it has been pretty damp. The spirits of my people are improving under the let-up of strain, but they are showing a few physical signs of the over-fatigue. We have been having a number of infected fingers and other little things and have really broken our good health record. I have one nurse, Miss S., away at E. for a ten days’ change at a lovely Convalescent Home for Sisters, and another is to go soon,--Miss M. who had a bad attack of bronchitis. Miss S. had a lot of little infections which showed she was below par. Then yesterday we had our most serious trouble, for we had to send Miss S. to the Hospital for Sick Sisters here in Rouen to have an operation due to an old injury. The British officials could not have been more courteous to us. They made it possible for our men to perform the operation and let one of my nurses go and stay with Miss S. The operation was a very long, serious one. Major M. and Major C. operated and Miss S. assisted while I held the arm. The operation was performed in the Operating Room of No. 8 General Hospital, which is five minutes’ ride from the “Sick Sisters” where there is no Operating Room. She was taken back in an ambulance before she was out of ether. The “Sick Sisters” is a lovely place on the other side of Rouen, about 8 miles from here. We go and come in a little Ford Ambulance. Major M. and I have been over to-day, and everything is getting along beautifully. We took our second patient over with us to-day,--Miss P., with a bad infected thumb. We are not supposed to keep a sick sister in Quarters more than 24 hours. We have been very lucky up to now in not having to send any one away. But this hospital is ideal. It is taken care of by British doctors and Sisters and is in a lovely location, higher than the spire of Rouen Cathedral. It is worrying to have my children sick, but it is good to know what excellent care they will get when they are sick enough to be sent away from us.
