Letter from Helena Gleichen, Hotel de France & d'Angleterre, Pauillac, to James Mackenzie Davidson Notes that, depending on how the money turns out, she may ask Mackenzie Davidson to send one of his tables and one of his screen localisers. Suggests that it may only be necessary for them to have the screen localiser, using it against their upright machine and creating a slide to hold it, and asks Mackenzie Davidson for his advice. Describes to Mackenzie Davidson an episode recently where they walked to a gorge in the forest and against the 'ampitheatre of rocks' were able to hear the guns at the frontline. Notes that the nearest front is over 100 kilometers away, but wonders if the gorge made a sounding board of sorts. 5 July 1915
