This is the construction of a new 2nd Battalion aid station in the T-Bone Hill sector of the front line. In the background is the old aid station not nearly as well constructed as this one. The wood walls showing were about like railroad ties and were to be covered with sand bags like the roof. This was on the same hill as battalion headquarters which was located a few hundred yards beyond this view. The battalion surgeon spent a lot of time working on his new surroundings.
