Eye Witness was a series of short monthly newsreels produced by the NFB during the post-war period. Each installment included several short reports on issues of interest to Canadians. Episode No. 58 includes Canadian Works with U.N.’s Problem Refugees, in which Dr. Robert Westwater, an Ottawa educator, helps UNESCO deal with problems precipitated by the dislocation of Arab populations following the 1948 war in Palestine, and Tractor Train Pushes through Northern Wilderness, which shows how supplies needed to build the Ungava railway and hydro project are transported by tractor trains through snow-bound roads and rough country.
