Old Ensor suddenly appeared yesterday. I am very glad. Such a hot day. Simply roasting and airless in the trenches. We had a disturbed night, as we had a secret test of our communications with the Artillery at 2.00 a.m.—rockets, telephone, signalling and by runner. It worked out all right. The morning was very foggy so neither rockets or signalling were visible. After that was over I visited the marsh Posts with the Padre, and returned to bed at about 5.30. Slept till 7.30 a.m. Tin hats very hot. A fairly peaceful day; they burst some shrapnel over the village in the p.m., and M.G.s are active as usual tonight. Probable that we shall not go back for a rest for a bit yet.
