Tank Carts Road making our Tramways. The whole of the position was organized with sanitary area plans prept & Latrines properly built & roofed with pits Trench privvies etc designed & written instructions issued - all this in conjunction with unanimous approbation of the A.O.M.S. & S.O. & Div Eng - the first were not inclined to agree with me but quite came over to my way of thinking afterwards & have heartily co-operated. 2. Prepared plans for

  a. proper bomb proof & weather proof shelters for Officers & men in Fire trenches,
