Been out all day. Left by car at 9.00 a.m., and returned 5.00 p.m. Attended a gas demonstration, about 25 miles off. Rather interesting. Lecture in morning, and show in afternoon. It appears that we have inflicted a good deal more loss on the Bosche by gas than is generally known. Still it’s a dirty game. Please send 500 more socks at once. Goodwin, who commands 12th [Royal Irish Rifles], came with us today; cheery nice fellow. Snow all day.
