Marian Lawrence Peabody "War Work" June 11, 1917 to Dec 7, 2017 quoting excerpts from her diary

Someone excerpting Marian Lawrence Peabody diary about "War Work" June 11, 1917 to Dec 7, 2017 quoting excerpts from her diary P. 10 Mentions "the awful disaster in Halifax. A munition ship collided with a Belgian relief ship and exploded, destroying half the city." Someone is quoting Peabody's diary, I presume after World War II since she puts in parentheses that Halifax explosion was the largest human caused explosion before Hiroshima.
