SPRINGHILL, N.S.--A year later, Oct. 13, 1959, Joe McDonald looks down the sealed off slope of the No. 2 colliery at Springhill, N.S., where he was trapped for six days last October when an undergroung earth tremor wrecked the mine. McDonald has survived two disasters. He was trapped for three days following an esplosion in No.4 colliery in 1956. In last year's tragedy, which took 75 lives, he suffered a badly fractured leg.
