Dear Betty:- I am waiting.to be relieved at a post about a quarter of a mile from the lines. It has been quite lively here for the past four days. In the daytime, shrapnel shells come over and at night, the Austrian machines and gun bullets go whizzing by sometimes. The country is so flat that one can't tell at all how close the lines are. I thought until I was told differently yesterday, that they were about a mile distant. I was up in the first lines yesterday, but will write a letter about that. All 0.K.
